Fenbendazole and Ivermectin for Cancer: A Case Series of Over 700 Patients (2026)

By Editorial Team June 07, 2026

Medically Reviewed by: OneDayMD Editorial Team | Last Updated: May 2026

Anecdotal reports and preliminary studies suggest that ivermectin and fenbendazole, both antiparasitic drugs, may have potential anticancer effects when used alongside other treatments.

Many people immediately dismiss the potential of ivermectin and fenbendazole when they learn it is “horse or dog medicine”. That initial reaction is overcome when genuine human success stories are told including the lack of serious side effects.

The testimonials you are about to read are from individuals who have bravely shared their experiences in the hope of inspiring and uplifting others. These are raw human accounts, unfiltered by gatekeepers—not peer-reviewed studies—but they offer insights that may be valuable to those searching for options.

However, we acknowledge that robust clinical trials are needed to provide more conclusive scientific evidence.

Conclusion

Editor's Preface

We began this article with just a handful of cases, but it has since expanded to include over 500 case reports from diverse sources.

“The cure for cancer? It all started with a single case study.”

Let’s start with the mainstream perspective—the one you’ve likely heard from conventional cancer specialists or major media outlets:

We need larger, high-quality studies before making formal recommendations.
There is no evidence that fenbendazole works, or its effectiveness is unproven.
There are no randomized controlled trials on fenbendazole.
This is ‘false hope.’ If something sounds too good to be true, it probably is.

You may have discovered this article through a social media link rather than mainstream news or major search engines. Why is that?

Unlike traditional platforms, social media allows the rapid sharing of niche or underrepresented stories—giving content like this a chance to reach those who might otherwise miss it.

When diagnosed with cancer, most people rely on discussions with family members and doctors. However, they often encounter conflicting recommendations—some professionals support exploring fenbendazole, while others strongly oppose it.

So, what’s fact and what’s fiction? The answer depends on science and research. However, science can be biased, manipulated, or selectively presented to fit a particular narrative. That’s why it’s crucial to do your own research in consultation with a trusted doctor. Many media references rely on outdated studies or cherry-picked data that align with a specific viewpoint.

The Case for a Precautionary Approach

According to The Cochrane Review’s editor-in-chief, Karla Soares-Weiser (source):

“Lack of evidence of effectiveness is not evidence that the interventions are ineffective… Waiting for strong evidence is a recipe for paralysis. Public health officials must take measured gambles, based on circumstantial evidence from the reviewed studies and other sources. When protecting the public from harm, they must act even when evidence is uncertain (or not of the highest quality), particularly when the harms and costs of such action are likely limited.”

Even if the chance of fenbendazole helping is small, individuals have the right to explore it as an option.

Dr. John Campbell, a health educator with over 3 million YouTube followers, shared (video) a compelling perspective in his video on fenbendazole and ivermectin for cancer:

“People have the right to try. They could try these drugs... and we could track them over time. We could build national cohorts of tens of thousands of patients in no time… then hand it over to statisticians to analyze the data and uncover the mathematical truth. This could be done, and in my view, it should be done.”

Real Stories, Real Hope

The testimonials you are about to read are from individuals who have bravely shared their experiences in the hope of inspiring and uplifting others. These are raw, unfiltered accounts—not peer-reviewed studies—but they offer insights that may be valuable to those searching for options.

It’s important to acknowledge that the Fenbendazole protocol is not a universal cancer cure.

We are not here to advocate for or against any treatment—whether conventional (surgery, chemotherapy, radiation, immunotherapy) or alternative approaches. Our focus is on effective and safe strategies that may offer hope and improved outcomes.

This article is not meant to be your final guide, but rather a step in your journey toward better health. We encourage you to seek out additional resources, ask questions, and explore all available options.

A Final Word of Encouragement

If you have stage 4 cancer, don’t lose hope. Your story could be the next inspiring success.

“N=1 is the future.” – Michael Snyder, Stanford Medicine (source)

Instead of relying solely on large-scale studies, case reports focus on individuals—allowing people to directly assess how specific interventions affect their unique health profiles. As Snyder told The Epoch Times,

“We are all different, and now we can collect a lot of data on a single person or a few individuals to make very specific recommendations.”

In the end, science evolves. Until then, the right to try belongs to you.

Introduction

Fenbendazole, often referred to as FenBen, is an anthelminthic medication initially developed to eliminate roundworms and pinworms in animals and humans.

Fenbendazole is a broad spectrum anthelmintic used against gastrointestinal parasites including: giardia, roundworms, hookworms, whipworms, the tapeworm genus Taenia (but not effective against Dipylidium caninum, a common dog tapeworm), pinworms, aelurostrongylus, paragonimiasis, strongyles, and strongyloides that can be administered to sheep, cattle, horses, fish, dogs, cats, rabbits, most reptiles, freshwater shrimp tanks as planaria and hydra treatments, as well as seals.

Common brand names include Pancur, Panacur C and Safe-Guard.

Note: In everyday conversations within the fenbendazole communities, you might encounter Fenbendazole referred to as Phenbendazole, Panacur or SafeGuard. This interchangeability is representative of the common use of the trademarked name; it signifies a consensus within these circles that these terms denote the same medication. Fenbendazole is the active ingredient in all these products. Molecular formula for fenbendazole is C15H13N3O2S.

However, it is also being used by humans in a cancer treatment method known as the Joe Tippens Fenbendazole Protocol.

Although first introduced in 1961, it wasn't until 2009 that FenBen's potential as a cancer treatment was discovered during a glioblastoma (GBM) study at Johns Hopkins University. Since then, numerous case reports have demonstrated FenBen's effectiveness in treating various cancers, including lung, kidney, liver, breast, prostate, melanoma, bone, ovary, colon, and brain tumors.

Case 4: 75 year old FLORIDA man with 14 cm Intrahepatic Cholangiocarcinoma

Dr. William Makis posted on X.com in January 2026:

IVERMECTIN and MEBENDAZOLE Testimonial - 75 year old FLORIDA man with Intrahepatic Cholangiocarcinoma reports after 3 months: 14cm tumor necrotic inside!

A positive "Florida man" story for a change! 75 year old Florida man with Cholangiocarcinoma On August 13, 2025 he started: Ivermectin 105mg/day Mebendazole 1000mg/day From the patient: "Dr.Makis, my Oncologist is very pleased with my response to chemo and immunotherapy treatments....she is amazed at how well I am tolerating the treatments and is not aware I am using your protocol of Ivermectin, Mebendazole, etc..." "I'm glad you got to help us here in Florida with your recent visit" PET Nov.24, 2025: "large infiltrative mass involving majority of the right hepatic lobe...on today's exam this does demonstrate central regions of photopenia compatible with necrotic change." Key POINTS: 1. Ivermectin and Mebendazole significantly reduce chemo side effects!! 2. TUMOR NECROSIS - I have seen this happen several times, so I am raising it as an important thing to keep an eye on. Large tumors, especially Cholangiocarcinomas, will first die in the center when responding to Ivermectin and Mebendazole (and usually chemo). During this time, the tumor size itself may not change, but inside the tumor, usually in the center, the tumor liquifies as it is dying. This is described as “necrosis”, or hypodense on CT, or “photopenia” on PET/CT (as there is no cancer metabolism going on in dead tumor tissue so it doesn’t light up on PET scan) The tumor size eventually starts to decrease but it takes several months for the body to remove a significant amount of dead cells from inside the tumor to make that obvious on CT.

Case 3: 85 year old Toronto, Ontario man with Cholangiocarcinoma (Klatskin Tumor)

Dr. William Makis shared on X.com in December 2025:

IVERMECTIN, FENBENDAZOLE, CBD Oil Testimonial - 85 year old Toronto, Ontario man with Cholangiocarcinoma (Klatskin Tumor) reports after 4 months - goes from progressing to Complete Remission!

Trigger Warning! This post may cause seizures in some because there is no chemo and no mainstream Oncology Treatment. You have been WARNED!!

STORY: 85 year old Toronto, Ontario man with Early Stage Cholangiocarcinoma, 2.8cm tumor involving common hepatic and common bile ducts. From June 21, 2025 to Oct.15, 2025 (4 months) he took:

Ivermectin 64mg/day, then 48mg/day
Fenbendazole 500mg/day
CBD Oil 100mg/day

Results after 4 months: Complete Remission!! KEY POINTS: No chemo, no radiation, no immunotherapy. Yes, he had radiation 5 months before starting the Ivermectin Protocol (in Jan.2025) but May 2025 CT showed his tumor was still growing after the radiation therapy!! The bile duct tumor grew to 2.8cm from 2.3cm after radiation therapy. An 85 year old man can take Ivermectin and Fenbendazole safely with no side effects. This really puts into perspective when I hear from 40 year olds who are afraid to take either, because their Oncologist told them it could be “dangerous”. These were mild doses of Ivermectin and Fenbendazole. Some tumors respond incredibly well to Ivermectin, Fenbendazole, Mebendazole, even at mild doses. Cholangiocarcinomas are in this category. This was truly the simplest possible solution and the patient is now in remission. I often present Stage 4 cases but remember, this is an early stage case, and shows you what is possible if you start Ivermectin and Fenbendazole at a much earlier stage.

Case 2: 48 year old TEXAS woman with Stage 4 Cholangiocarcinoma

Dr. William Makis shared on X.com in December 2025:

IVERMECTIN and FENBENDAZOLE Testimonial - 48 year old TEXAS woman with Stage 4 Cholangiocarcinoma. "She lasted in Palliative Care Unit twice as long as anyone expected"

Sometimes you get a beautiful story from Hospice... You will have to read the whole story but here is a highlight: "I did want you to know though...it was the only thing she took (secretly) while in the hospital for her last month." "She was in multi organ failure... but her kidney doctor kept saying, "I've never seen this before, but your kidneys seem to be improving in function. I have no idea why." But we knew why. (I have another cousin with stage 4 breast cancer who is also using IVM & FBZ and her kidneys were weeks away from dialysis and now are normal function. All she takes is IVM & FBZ). "Anyway... XXXXX lasted in the Palliative Care Unit at XXXX twice as long as anyone expected. She took IVM & FBZ consistently her last three weeks in hospital and that gave her a little more time with family and friends." "THANK YOU. Your research and constant perseverance makes a BIG difference... People are researching and pursuing alternative protocols for their health because of you. And they have HOPE!"

Case 1: 53 year old Stage 4 Cholangiocarcinoma Cancer patient with 15 cm tumor

Dr William Makis shared on X/Twitter (December 2024 update):

IVERMECTIN and FENBENDAZOLE Testimonial - 53 year old Stage 4 Cholangiocarcinoma Cancer patient with 15cm tumor declared "Cancer Free" after reaching out to me 14 months ago!! This is a very special story. 53 year old Canadian Cancer patient diagnosed with Stage 4 Cholangiocarcinoma, metastatic to liver in March 2023. Multiple lesions, largest 15cm. Patient had chemo and reached out to me in October 2023. "I was taken off the bag of immunotherapy because the tumour didn't shrink" "Second oncologist...was worse than the oncologist I have now...told me my supposed mortality chart and to watch for "the end" because I'd be lucky to make it to summer (2024)"

"I'm terrified...I'm losing hope" I replied on Nov.3, 2023: "Don't lose hope..

Ivermectin is 1mg/kg/ or 2mg/kg daily
Fenbendazole is typically 444mg daily
Melatonin is 100mg-300mg daily" (see note below)

Life went on...then I get an email in July 2024: "I'm still here thanks to you :)"

We went to work. Oncologists were pressuring to give her more and more chemo. In November 2023, she had started Fenbendazole 444mg (Panacur) and Melatonin 100mg

In August 2024 we added 150mg of Ivermectin or 2.5m/kg/day, and CBD-THC Oil. You heard that right. Ivermectin 2.5mg/kg/day. And then... December 12, 2024: "Cancer Free".

Note: "Melatonin induces apoptosis in cholangiocarcinoma cell lines by activating the reactive oxygen species-mediated mitochondrial pathway" (source)

Case 1: Stage 4 HCC (HepatoCellular Carcinoma) liver cancer (September, 2021)

I was given less than two years to live in 2020 when I was diagnosed with stage 4 (metastatic) HCC (HepatoCellular Carcinoma) liver cancer. I received radiation directly onto the tumors and went for immunotherapy which did not bring any improvement to my state I was in. My wife and family did research and came across the fenbendazole protocol. I had nothing left to lose, so I decided to give it a try.

I used 2000mg of fenbendazole every day of the week. I was supposed to get my last course of chemotherapy on 5 tumors in mid 2021 and the doctor has found only one tumor showing up.

About a month after I had to go in for a MRI scan to see what was going on and the doctor again confirmed NED, no active trace of cancer in my liver was found, only scar tissue and a bit of inflammation present.

This was an emotional experience for me and I truly believe that fenbendazole saved my life!

Case 1: January, 2022*

*Update January 2025:

Published as a January 2022 case testimonial on Heal Navigator:

"I was diagnosed with borderline active Multiple Myeloma about 5 years ago. As the symptoms got more they wanted to put me on chemotherapy but refused. I eventually got diagnosed with several other diseases like Lyme disease, Morgellons disease, RA, chronic skin conditions, Fibromyalgia, etc. I was in such pain. This is when I decided I had enough and got word of the fenbendazole protocol and decided to give it a go.

As time went by being on this course, I saw improvement with every trip to the doctor. I eventually became more functional and could start returning to my life after being under for a few years.

I then had to relocate due to work and it took me almost a year to find another oncologist to check my results. He was completely amazed after hearing my story and confirmed to me that I fully recovered from Multiple Myeloma. This is a miracle. I told the doctor that I have been using fenbendazole and even the doctor was astonished by my past results, stating that I am in a better condition than ever before!

The doctor still monitors me today on my fenbendazole usage which I take every day to ensure that my M-count does not spike. I am grateful and thankful to be pain free today. This is all thanks to fenbendazole."

18. Myelodysplastic Syndrome

Dr William Makis shared on X/Twitter (January 2025):

IVERMECTIN and FENBENDAZOLE Testimonial - 74 year old former Olympic athlete with Myelodysplastic Syndrome (MDS) post Moderna COVID-19 mRNA Vaccines - first improvement in blood counts in 2 years! Another short but inspiring story! 74 year old former Olympian had two Moderna COVID-19 mRNA Vaccines and recently developed MDS (Myelodysplastic Syndrome). From his wife: "I'm grateful I found you...he is on the Ivermectin and Fenbendazole regime I found on your site" After 1 month: "My husband had his blood tests last week and met with Oncologist today. For the first time in 2 years his blood counts are up and I can only attribute that to your Protocol of Ivermectin and Fenbendazole which he has been following for just a month" And now my favorite part "You are a miracle worker and I think after the Rogan/Gibson podcast you will be very famous in the USA" Ok that was too sweet of her! The doses used for 1 month:

24mg Ivermectin (daily)
222mg Fenbendazole

These are relatively small doses but still effective! I've had many requests to help patients with Myelodysplastic Syndrome (MDS) and the research is very limited but guess what... several MDS patients and I are now working on it! Many blood disorders respond to Ivermectin and Fenbendazole and this is a hot area of research for those of us staying one step ahead of mainstream oncologists and hematologists!

19. Oral Cancer

Refer to Head and Neck Cancer (chapter 10).

20. Ovarian Cancer: Fenbendazole, Mebendazole and Ivermectin

Case 3: 63 year old woman with Stage 4 Ovarian Cancer metastatic to peritoneum (April 2025)

Dr William Makis shared on X/Twitter:

IVERMECTIN and MEBENDAZOLE Testimonial - 63 year old woman with Stage 4 Ovarian Cancer metastatic to peritoneum sees CA125 drop from 2138 to 357, most cancer gone on PET! Beware of inexperienced Integrative MDs who want to play with Ivermectin and Fenbendazole!

This is a success story that almost wasn't.

63 year old woman with Stage 4 Ovarian Cancer metastatic to peritoneum. In early October 2024, she saw an integrative MD who put her on low dose Ivermectin (24mg) and Fenbendazole 300-600mg, eventually increasing to 1000mg a day. Her CA125 increased from 1097 to 1668 (+ Fenben/IVM) to 2628.5 by mid Nov.2024!

Her CA125 rose from 1668 to 2628 after being on Fenbendazole and low dose Ivermectin for over a month! Then she came to me.

I switched her from 1000mg Fenbendazole to 1000mg Mebendazole and increased the Ivermectin from 24mg to 72mg. Her CA125 from that point onwards: 2628.5 to 853 to 619 to 357 (!!) PET/CT Scan done March 11, 2025 showed:

“extensive peritoneal carcinomatosis seen previously is essentially resolved” “retroperitoneal adenopathy seen previously has returned to normal”
“left axillary adenopathy seen previously has resolved on both CT and PET images” “most of the pelvic adenopathy seen previously has returned to normal on CT and PET”
“suspected capsular implant seen previously at the posterior aspect of the spleen is no longer visible on CT or PET”

Lesson:

Most Integrative MDs don’t know what they’re doing when it comes to Ivermectin and Benzimidazoles. They get the dosing and combinations wrong. This patient wasn’t responding to low doses of Ivermectin or Fenbendazole and the Integrative MD increased the Fenbendazole dose to 1000mg, but the CA125 rose regardless, from 1097 to 2628!

Ovarian Cancer is known to respond to Mebendazole and Ivermectin but South Korean researchers discovered it doesn’t respond well to Fenbendazole. Some health professionals are attracted to the promise of repurposed drugs but wouldn’t know what to do at the sign of first trouble with their Protocol. Imagine coming to a health professional who has no idea what to do when their Ivermectin Protocol fails. You wouldn't go to an inexperienced hairdresser, barber, or car mechanic, for an important job. And what's more important than Stage 4 Cancer?

Case 2: 40s-year-old Stage 4 Ovarian Cancer (Dec 2024)

According to Dr William Makis (X/Twitter):

IVERMECTIN & FENBEDAZOLE Testimonial - 40s year old Stage 4 Ovarian Cancer patient declared "CANCER FREE" after 2 months 40s year old Stage 4 Ovarian Cancer patient followed at a large US Cancer Centre (Mayo Clinic), reached out to me in July 2024 Patient was diagnosed in Feb.2024 with Stage 4 Ovarian Cancer (High Grade Serous Carcinoma) She had 4 cycles of neoadjuvant chemo, then cytoreduction (surgery) June 24, then plan was for 2 additional cycles of chemo. Post Surgery Cancer Clinic Visit in July 2024: plan was for 2 more chemo cycles - patient then reached out to me after her visit. CA125 on July 15, 2024 peaked at 86.7 (pre-surgery it was 41.7) Even though much of the tumor was removed, the CA125 had jumped from 41.7 to 86.7, indicating rapid cancer growth and spread IVERMECTIN: We started a medium dose Protocol:

Ivermectin 1mg/kg/day
Fenbendazole 444mg/day
Melatonin 100+mg/day

6th cycle of chemo

Two months later she was CANCER FREE.

Do you think the Chemo did it? The same chemo that after 4 cycles resulted in a CA125 of 41.7? And then rapid progression right after surgery? I don’t think so. It was the combination of chemo + IVERMECTIN Protocol. Now, as of Dec.21, with a CA125 of 16 (in the normal range), she’s been CANCER FREE since end of September.

Case 1: Advanced Ovarian Cancer (October 2024)

According to Dr William Makis (X/Twitter):

IVERMECTIN and MEBENDAZOLE Testimonial in a patient with Advanced Ovarian Cancer.

3 weeks of high dose regimen results in CA125 cancer marker drop of 30%!

Ovarian cancer is very responsive to Ivermectin but people forget about Mebendazole (FDA approved version of Fenbendazole). (Hint: combine them)

We hit this cancer hard and have it on the run 3 weeks in!

Note: Although technically mebendazole is not the same as fenbendazole, both mebendazole and fenbendazole are part of a larger group of drugs known as benzimidazole*, which are anthelmintic drugs (i.e., drugs that kill parasitic worms).

*The class of drugs known as benzimidazoles includes fenbendazole, mebendazole, albendazole and flubendazole.

Fenbendazole and mebendazole are similar in that they both eliminate parasitic worms, but there is a difference. Mebendazole is approved for human consumption by the FDA, while fenbendazole is only approved for veterinary use and has not been approved for human use.

Mebendazole is the form that is approved for human use while fenbendazole is approved for veterinary use. The main difference is the cost. Mebendazole is expensive ~$450 per pill (two pills of mebendazole cost just $4 in the UK.), while fenbendazole is inexpensive ~48 cents per 222 mg free powder dose (Williams, 2019). Albendazole is the form used to treat intestinal parasites in India and these cost 2 cents per pill.

While most of the pre-clinical research uses mebendazole, probably because it is the FDA-approved-for-humans form of fenbendazole, virtually most of the self-treating clinical reports involve the use of fenbendazole.

Case 2: IVERMECTIN & FENBENDAZOLE for Stage 4 Spindle Cell Sarcoma

Dr William Makis shared on X/Twitter (November 2024):

IVERMECTIN & FENBENDAZOLE Testimonial - 70 year old woman with Stage 4 Spindle Cell Sarcoma gets 60% tumor shrinkage & multiple metastases disappear with low dose protocol 70 year old woman with Stage 4 Spindle Cell Sarcoma originally in the right leg, with lung metastases.
She took the following:

Palliative chemo (was not expected to help and it's all the doctors had left to offer)

222mg Fenbendazole 3 days on / 4 days off (Joe Tippens Protocol)

12mg Ivermectin 3 days on / 4 days off

Unexpected Results: tumor shrinkage by 60% & disappearance of multiple lesions (!!)

My Take… Spindle Cell Sarcoma is a cancer that’s notoriously difficult to treat. The response rate of chemo is on the order of 20% (which means 80% of patients don’t see ANY improvement). The ones who respond see minimal results. To get tumor shrinkage by 60% and disappearance of multiple lesions is stunning. The chemo was palliative and was not expected to help in this case.

So yes, it wasn't the chemo. Sorry. And these were VERY LOW doses of Ivermectin & Fenbendazole !! I tend to suggest higher doses as cancer killing with Ivermectin & Fenbendazole is dose dependent.

Case 1: September, 2023

Condition: Alveolar Rhabdomyosarcoma (Bone and Muscle cancer)

When my 13 year old son was diagnosed, I basically became a cancer researcher!
I discovered a few new very promising treatments that are close to being ready for pediatric use, and I also came across Joe Tippen’s story. I joined a couple of large, international Facebook groups related to the Protocol, which are by far the most positive of all of the cancer-related groups I’m in, and have the most success stories. I connected with a mom in the group whose 2 year old has the same type of cancer as my son, which had spread to his lymph nodes during frontline chemotherapy treatment. She started him on Fenben and his next 2 scans so far have been clear!
I would do anything to help my son beat the odds, and I came to the conclusion that it would be far more dangerous NOT to give him repurposed meds than to give them.
My husband supported my decision, but wanted some medical oversight, which we have received from Heal Navigator.
We noticed an improvement in our son’s energy level and general health after just 2 days of giving him the Fenben! He had zero side effects, besides feeling a lot better.
I hope and pray that is a sign that it’s doing what we need it to! If you’re hesitating about getting started, I would encourage you to go for it!

, this highlights an Australian man with Stage 4 malignant melanoma with metastases to multiple sites. He reportedly achieved a "cancer-free" status after 12 months using ivermectin and fenbendazole.

Case 8: Stage 4 Melanoma with mets to lymph nodes

Shared by DavidCarl (X/Twitter):

"As I’ve told you, my wife had stage 4 melanoma with mets to lymph nodes. She started taking ivermectin before you released your protocols, 1mg/kg. Weeks later you published your protocols and I bumped her to 2mg/kg. I added 444 mg of fenbendazole. Her last pet scan was approximately 6 months where she was cancer free. Her oncologist was all smiles, but I never told him I was giving her the protocol. She continues to take .5mg/kg of ivermectin 6x week and 3x week of 444 mg fenbendazole. She was taking immunotherapy for about a year before I read about ivermectin. Her lesions were having moderate response to the immunotherapy per pet scans. After putting her on ivermectin, 45 days later with a pet scan she presented cancer free. We were blown away. I almost cried. Doctor this is the hope you’ve given us. Your stories continue to give my wife confidence. It is like a big dark cloud we lived with was lifted."

Case 7: Stage 3B Melanoma with liver failure

Shared by Dr William Makis (X/Twitter) - February 2025:

IVERMECTIN, FENBENDAZOLE and MEBENDAZOLE Testimonial:

FROM THE BRINK OF DEATH - Stage 4 Melanoma patient with extensive liver metastases given 2-3 days to live! Survives and most metastases are gone!

If you only read 1 of my testimonials EVER, make it this one. Canadian patient had Stage 3B Melanoma 5 years prior. In Dec.2024, he presented to emergency in liver failure.

"He was told (by an Oncologist) Dec.2nd that he had 2-3 days to live and was in liver failure as his entire liver was consumed with tumors".

(Diagnosis: Stage 4 Melanoma recurrence with extensive liver metastases & liver failure) “The only thing he (Oncologist) could suggest to try was Bractovi and Mektovi but has never given it to anyone with their liver in such bad shape – we are told that it is completely taken over with both cystic and solid lesions. Against our belief we were faced with a ‘try or die….” "He was given 1-2% chance with Braftovi/Mektovi so started that Dec.3rd" "I reached out to you shortly thereafter and started your protocol. The CT results from Jan.30th (2025) that I am sending you show significant regression or complete resolution!!!"

Braftovi/Mektovi - 59 days

Ivermectin - 43 days

Mebendazole - 38 days

Fenben - 28 days MAKIS IVERMECTIN CLINIC PROTOCOL Implemented:

Ivermectin 1mg/kg/day (43 days)

Mebendazole 400mg/day (38 days)

Fenbendazole 444mg/day (28 days)

Yes, you read that correctly. This is what's called "weighing the risks and benefits".

CT RESULTS: "All previously detected hepatic lesions have markedly regressed or resolved." "Excellent response to the interval instituted treatment regime, where there has been marked regression of the metastatic liver disease with associated significant reduction in the associated hepatomegaly. "There has been significant regression of the metastatic lymphadenopathy of the root of the small bowel mesentery" "there has been complete resolution of the underlying anasarca and ascites" "There are presently no signs of acute intra-abdominal/pelvic process observed" ----- My Take… Do you know what is probably the single most frustrating question I get every day? “Is Fenbendazole safe? My doctor told me it will damage my liver!” "My doctor told me Fenbendazole will destroy my liver" Let me summarize: Stage 4 Melanoma patient with extensive liver metastases told he had 2-3 days left to live... in LIVER FAILURE...

Implemented a Protocol with Ivermectin, Fenbendazole and Mebendazole!

And is alive 2 months later with all metastases either shrunk or gone! FROM THE BRINK OF DEATH… If anyone ever tells you that Fenbendazole or Mebendazole will damage your liver, know that they are lying to you, and if you want to, show them this story!

Case 6: Basal Cell Carcinoma (BCC)

In this December 2024 case report published by Canadian Oncologist Dr. William Makis, we note the pictorial resolution of basal cell cancer [BCC] to the point that the patient may have to cancel his appointment for a planned surgical removal. One cannot surgically remove a basal cell cancer [BCC] that no longer exists.

This gentleman reports he is a long-time reader of Dr. Makis and was particularly interested in his reports of Fenbendazole and Ivermectin. He contracted basal cell cancer on his face in February or March of 2024, and did what most of us would do - he booked an appointment with his GP in June 2024, apparently the first available.

The soonest he could get scheduled for the Dermatology referral was sometime in November. Having nothing to lose, he decided to apply Fenbendazole paste per the articles he had previously read, and to his pleasant surprise the persistent non-healing skin cancer of seven months began to shrink in size.

FenBen Treatment from September 25 through October 28, 2024

By the time of his November Dermatology appointment, there was very little to biopsy, yet it was done. He reports the Dermatologist was not the least bit interested in his tumor shrinkage with the Fenbendazole paste. Instead, the Dermatologist booked him for a tumor removal appointment three months later in February 2025.

The patient continued to apply the paste for the next month following the November biopsy, and here is what the BCC looked like as of December 6, 2024.

Result of FenBen Topical Treatment from September 25 through December 6, 2024

He writes,

“I’m still treating it once a day with Safeguard 10% Fenbendazole and it seems to still be improving. So I’m undecided about whether I need to have anything removed. I guess I’ll see how it goes over the next while. Maybe it’s deep into the tissue despite having improved the surface cells. No idea.”

Dr. Makis writes in response that patients who take matters into their own hands seem to do better.

Case 4: Melanoma (Skin Cancer)

Shared by Dr William Makis (X/Twitter) - Last Edited: October 2024:

FENBENDAZOLE Testimonial in Stage 4 Melanoma Cancer patient - didn't listen to Oncologist's advice to stop Fenben, and is now cancer free.

There is a key lesson here. The Oncologist gave the opposite advice of what was good for the patient. That's because the Oncologist was following Cancer Guidelines set by Big Pharma (like Pfizer). If this patient had followed his Oncologist’s advice and stopped the Fenbendazole, he would still have active Stage 4 melanoma metastases with a much worse prognosis. Maybe he'd already be dead. How do you know if you have a good Oncologist? Ask them how many COVID-19 Vaccines they took! The only correct answer is "0".

Case 3: May, 2022 - Squamous Cell Carcinoma

In September 2021, I went to the cancer clinic to get my second PET scan done after receiving the news in March 2021 that I have been diagnosed with cancer, and learnt that day that my tumor has shrunk to half the size it first was. There were still signs of lymph nodes increasing or being classified as unknown results. I continued the use of the fenben protocol along with a whole bunch of other supplements to take on a daily basis, as within 5 months results improved in comparison to a whole year of fighting off the protocol before with little to non improvement in results. I strongly believe in this protocol and in case you wondered – I am not on any chemotherapy/radiation/immunotherapy or any other western medicine use – this is a full on natural and holistic journey I went on, and I am happy to share my current protocol with all cancer patients out there:

Serrapeptase (at midnight)
Vit D & K2, Tudca 500mg, Graviola 1ml (on an empty stomach)
Varies supplementation with breakfast (like Vit C & B complex, probiotics, fish oil, curcumin, etc. along with fenben 888mg)
Multi-vitamin, turkey tail extract, fenben 888mg, and B17 apricot seed (with dinner)
Some more other supplements just before bed (like magnesium, Vit C, Graviola, high dose of melatonin, coffee enemas, etc)
Detox baths (1 x week)
Frequency music (before bed designed to kill cancer cells)
Mainly following a plant-based diet
Protein intake is limited to certain meats
Fresh whole foods/vegetables
Healthy fats only

I trust that this protocol I am following will guide a lot of people out of their state – just belief and trust the process along with the support from others who have been through this before. Good luck.

Case 2: October, 2022

In February and March of this year I was diagnosed with stage four melanoma. It had metastasized to my brain, lymph nodes, right lung, adrenal gland and right hip. My daughter pointed me to Joe’s story and this site. I started taking the fenbendazole protocol even before my oncologist gave me her treatment plan using Immuno therapy. The oncologist said that it had about a 30% success rate but not to expect any great results on the first scan after 4 treatments.

I had a PET scan last week and the results were almost too good to be true. Cancer basically gone. The tumor in my right lung had shrunk to less than half the size it was on the first PET scan. The uptake on that tumor decreased from 19.9 to 2.6. I was told by her that an uptake of less than 4.0 is no longer considered as cancerous.

I have been on the fenbendazole protocol for 166 days now. I received 4 immunotherapy injections using 2 different drugs. I can’t say for sure what definitively gave me these great results. Draw your own conclusions but I think the fenbendazole was largely responsible for the great results.

Case 1: January, 2022

At first me and my partner were unsure about trying alternative treatments in addition to the radiation my partner receives. With the help from a holistic healer and referrals from a couple of people in our community, we found out about the fenbendazole protocol and started to add the protocol along with a few other supplements to my partner’s daily intake/routine to aid in fighting the skin cancer on his neck.

25. Thymus cancer

October, 2022

Condition: Thymus cancer

Was diagnosed with Thymic Carcinoma 06/2022. Just finished week 8 of 12 week chemotherapy. I have been taking fenbendazole, curcumin, vit D & K, and CBD oil. We will do another PET scan in October and I fully expect the tumors to be completely gone or greatly reduced. Will update with the results asap. Blessings to all.

26. Turbo Cancer (Aggressive Cancer)

Experts are seeing a puzzling rise in cancer in people under 50 that appears biologically different from late-onset cancers. While some claim cancer rates have been rising for decades and attribute the increase to sugary drinks, lifestyle, and sleep disruptions, others say mRNA COVID-19 vaccines have caused an emergence of “turbo cancers”—and U.S. regulatory agencies have not addressed the ever-growing problem.

27. Uterine cancer

Case 1: 81-yr-old female with Stage 4 Endometrial Uterine Cancer (May, 2023)

My 81 yo mother, Virginia, found out she had recurrent Endometrial Uterine Cancer back in Sept 2022. Stage 4 and Mets to abdominal area, lymph nodes, chest cavity and lungs. Radiation was not an option and she opted out of chemo, which would have only bought her a few extra months but would have made her very sick and weak. The doctor put her on a Hormone Blocker to keep it from growing any more. (But if in the lymph nodes, does it really stop it??) The Dr. sent her home to be under Hospice care for the remainder of her short time left on this earth.

I was not ready to accept this!! (Plus, my father has dementia and desperately needs her!) I prayed to God to give us wisdom and guidance. Within 24 hrs., three people approached me about the Joe Tippen Protocol, which I had never heard of at that time. I figured I might ought to listen so I googled and got sucked in! I started learning everything I could learn about it. Then I presented it to mom. She said, “Well, what do we have to lose!?!?”

So, in Oct, through prayer and God’s guidance, I got her up and running on “things” (FenBen, Tudca, Serrapetase, Tumeric, High-Dose Melatonin, Turkey Tail, Apricot Seeds, drinking Baking Soda water, and rubbing on Frankincense). She has been very weak this whole time so we weren’t sure if it was working or not. We planned her funeral, etc….

Then, 5 mo later, her Dr insisted she have another scan. She was very apprehensive but agreed. We (including the dr) were blown away by the results!!! The tumors are either gone or have shrunk considerably!!!! (All but ONE, which basically has stayed the same). All of the ascites (malignant fluid all in her Ab area) was GONE!! The Doctor patted himself on the back but WE PRAISE GOD AND FENBEN!!!

We take one day at a time and hope and pray for the best for years to come but, for today, things are going well!!! (Other than her weakness)

*UPDATE: I added her protocol as a picture so take notice for those interested.

Case 2: Stage 4 Endometrial Cancer (January, 2023)

Condition: Endometrial carcinoma

In May 2021 I was diagnosed with stage IV endometrial carcinoma. I went through 6 months of hard chemo and 12 months of Maintenance chemo. March 2022 I started fenbendazole working up to 2000 mg a day, along with other supplements. I had a consult this month with Zahara, and she recommended tweaking a few things and adding a few more supplements. I worked hard on my mindset and made sure I surrounded myself with positivity. I received the best news today I could hope for. No evidence of active disease. Never give up!

Cancer treatment should be part of a multi-modal approach in order to provide the best possible outcome. Diet and lifestyle changes are meant to run alongside conventional treatment. They are complementary, not alternative.
Cancer care is a team effort with the patient at the centre. Care should be supervised and coordinated by a primary healthcare provider. Patients with cancer should consult with their regular oncologist as well as an integrative provider/oncologist, in addition to their primary care provider and the supporting nurses, dieticians and other allied healthcare professionals.
While the term 'alternative' might imply opposition to conventional oncology, we prefer 'complementary,' 'integrated,' or 'holistic.' These terms better reflect the role of these strategies as part of a personalized value-added menu of strategies, ensuring the most effective and safe solutions for patients.

New & Improved Joe Tippens Protocol

In 2016, Joe Tippens was diagnosed with non-small-cell lung cancer with extensive metastatic disease. At the advice of a veterinarian friend, he took Fenbendazole together with nanocurcumin, and three months after starting these drugs his PET scan was completely clear.

Below is a modified version of the Joe Tippens protocol, a synergistic combination of fenbendazole, ivermectin and nutraceuticals, updated based on the ivermectin and mebendazole based protocol published in the Journal of Orthomolecular Medicine (2024):

Ivermectin (24 mg, 7 days a week) or in the case of severe aggresive cancers up to 1mg/kg/day.
Mebendazole (Dose of 200 - 400 mg/day) or Fenbendazole, commonly taken at 300 mg for six days a week, with doses increasing to up to 1 gram in cases of aggressive cancers.
Vitamin D (62.5 mcg [2500 IU] seven days a week).
Bio-Available Curcumin (600 mg per day, 7 days a week).
Enhanced absorption Berberine (500 mg per day) to starve your cancer of sugar.
Diet and Lifestyle: Eliminate sugar (BMJ 2023), adopt a whole-food diet, avoid ultra-processed foods (BMJ 2024), quality sleep, and proper stress management.

*Notes:

Please note that this protocol now includes the vital Vitamin D addition, with the one day off for the fenbendazole administration. This protocol represents the most comprehensive and cutting edge repurposed drug and vitamin treatment approach to date.
If you are taking ivermectin and mebendazole, you might not need fenbendazole. Consult your doctor.
Vitamin E: Removed from the protocol (Joe Tippens, July 22, 2020) due to interactions (e.g., with blood thinners).
