Medically Reviewed by: OneDayMD Editorial Team | Evidence Synthesis & Safety Review | Last Updated: August 2026 Quick Answer Ivermectin, fenbendazole, and mebendazole are antiparasitic drugs with laboratory evidence of anticancer activity.  The pharmacological rationale is real and merits continued, properly controlled trial investment. Patients should discuss any interest in these agents openly with their oncology team rather than self-administering veterinary or compounded formulations.  This article separates the genuine research question from the unverified claims, and outlines what to discuss with an oncology team before considering any of these agents. Background: Ivermectin and the benzimidazole anthelmintics fenbendazole and mebendazole have attracted sustained public attention as repurposed anticancer agents, driven substantially by social media case testimonials and a small number of peer-reviewed mechanistic studies. Objective: To synthesize the precl...

The alarming rise of colorectal cancer in younger adults has transformed what was once considered a disease of older age into an urgent public health crisis. In 2026, an estimated 158,850 new cases of colorectal cancer will be diagnosed in the United States, and 55,230 people will die from the disease — including 200 diagnoses each day in people younger than 65. ( American Cancer Society ) The good news is that we have a growing body of evidence—both high-quality scientific studies and patients’ personal experiences—that shows that diet and lifestyle changes can effectively stop cancerous cells in their tracks.  One of the most promising of these studies was performed on mice by a team of ten researchers at the University of Michigan. The study , “Dysregulated Amino Acid Sensing Drives Colorectal Cancer Growth and Metabolic Reprogramming Leading to Chemoresistance,” was published in November in the journal Gastroenterology. For this study, sc...

What you eat may influence prostate-cancer risk—but the science is more complicated than a list of “good” and “bad” foods. There is a growing body of research connecting diet, metabolic health and prostate cancer. Coffee consumption has been associated with lower prostate-cancer risk. Plant-forward dietary patterns appear favorable. Some studies suggest that green tea catechins may have chemopreventive potential. Higher consumption of dairy and calcium has been associated with a modest increase in risk in several observational studies. But there is an important distinction between an association and a proven cause-and-effect relationship . No single food has been proven to prevent prostate cancer. And no food should be considered a substitute for PSA testing, diagnostic evaluation, active surveillance, surgery, radiation, androgen-deprivation therapy, chemotherapy, targeted therapy or other appropriate cancer treatment. The more useful question is therefore not: “Which food kills prost...
