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...

Folic acid has been one of the great public-health success stories of modern nutrition. It has dramatically reduced neural tube defects when consumed before and during early pregnancy. But another question deserves a more careful look: could high supplemental doses of synthetic folic acid behave differently from the folate naturally found in foods? The answer is more nuanced than either side of the debate suggests. There is evidence that folate biology can be complicated, particularly once precancerous lesions or established tumors are present. Some randomized trials have raised concerns about high-dose folic acid supplementation and certain cancer outcomes. Other large studies and public-health reviews have not confirmed that recommended folic-acid intake causes cancer. So this is not a story about a vitamin that is secretly "causing cancer." It is a story about dose, timing, chemical form, nutritional status and disease context . Bottom line: Folate is an essent...

Medically Reviewed by: Dr Frank Yap, MD | Written by: OneDayMD Editorial Team | Last Updated: August 15, 2026 Medical disclaimer: This article is for education, not personal medical advice. Cancer progression or a new symptom needs prompt review by the treating oncology team. Do not stop, start, combine, or repurpose any cancer treatment—including supplements or veterinary medicines—based on online information. The right approach depends on the cancer type, stage, pathology, prior treatment, molecular results, overall health and treatment goals. Key takeaway: “Resistance” does not mean that nothing can be done. It means a cancer is no longer adequately controlled by a particular treatment. A new biopsy, validated blood-based test, imaging review and multidisciplinary discussion can sometimes identify an actionable change, a local treatment option, a different treatment class or a suitable clinical trial. In this guide What treatment resistance means Nine major mechanisms Resista...
