What’s a Poop Transplant and Can it Help Prostate Cancer?
A poop transplant also known as a Fecal Microbiota Transplantation (FMT) is when doctors take healthy bacteria from a donor's poop and transfer it into a patient's gut.
Think of it like planting a "good bacteria garden" in your intestines. These bacteria help your body fight cancer in two main ways:
- Trains your immune system: The good bacteria teach your immune cells to recognize and attack prostate cancer cells, like showing them a "Most Wanted" poster.
- Makes cancer treatments work better: These bacteria can help drugs like immunotherapy (medicines that boost your immune system) work more effectively, especially if they weren't working before.
Does it work?
- Studies show poop transplants helped some men with advanced prostate cancer live longer when combined with immunotherapy.
- It might also slow down cancer growth by changing the chemicals in your gut that feed cancer cells.
Can probiotic supplements help instead?
Probiotics (store-bought "good bacteria" pills) can help, but they're not as powerful as a full poop transplant. Here's why:
What probiotics can do:
- Slow PSA rise: A 2025 study found probiotics (like Lactobacillus) mixed with plant extracts (broccoli, turmeric) slowed PSA doubling time from 19 months to 62 months.
- Reduce side effects: Probiotics like Lactobacillus can ease diarrhea caused by prostate cancer treatments.
- Boost immunity: Some probiotics increase "fighter" immune cells in the prostate.
The catch:
- Limited variety: Probiotic pills contain 1-10 types of bacteria. Your gut has 30,000+ types. Poop transplants bring hundreds of strains at once.
- Not all probiotics are good: Some bacteria (like certain E. coli) might increase cancer risk. You may wish to ask your doctor which probiotics are safe.
- Depends on your diet: Probiotics work best with fiber-rich foods (vegetables, oats) that feed good bacteria.
Tips for Prostate Cancer Patients
- Best probiotics to try (ask your doctor first):
- Lactobacillus casei (reduces PSA)
- Bifidobacterium longum (lowers inflammation)
- Look for labels with "10+ billion CFUs" and "vitamin D." - Foods to eat:
- Yogurt, kefir, sauerkraut (natural probiotics)
- Broccoli, turmeric, pomegranate (boost probiotics' effects) - Avoid:
- Probiotics with *folate* (some bacteria make this, which might feed cancer).
Bottom Line
- Poop transplants are like a "supercharged reset" for your gut and immune system but are still experimental for prostate cancer.
- Probiotics are a safer, easier starting point and can help slow cancer growth when paired with healthy foods.
- Always talk to your cancer doctor before trying probiotics—some types could interfere with treatments.

When diagnosed, his mission is to help men avoid unnecessary prostate surgeries that can lead to devastating complications such as incontinence, bleeding, permanent impotence, and a loss of length.
Scott Oliver is not a doctor and does not offer medical advice; however, he is healthier and fitter than he has been in decades. Through his articles and videos, he shares hard-to-find, uncensored information on proven alternative therapies, effective fitness methods, and repurposed drugs, content that most doctors won’t mention and search engines suppress.
He is an accredited member of the National Writers Union (NWU) and the International Federation of Journalists (IFJ), the world’s largest organization of professional journalists. Scott is also the author of What If Cancer’s Best Defense Is Free? Sleep as a Defense Against Cancer: A Former Royal Marines Commando’s 4,000-Hour Research Roadmap, where he reveals how sleep repairs DNA, restores immunity, and strengthens the body’s natural defenses against cancer.
