What to eat when you have prostate cancer

Radiation therapy

Radiation near the pelvis may irritate the bladder or bowel, causing diarrhea or constipation. These changes are usually temporary.

If you have diarrhea, your care team may suggest temporarily limiting high-fiber foods, including:

  • Whole-grain breads and cereals.
  • Beans and lentils.
  • Raw or dried fruits and vegetables, except bananas.

Always follow guidance from your healthcare team, as recommendations may vary.
