Bowel leakage is not usually a sign of cancer. Most cases are linked to pelvic floor weakness, constipation, aging, or nerve problems. Rarely, leakage can happen when tumors in the rectum or anus affect the muscles and nerves that control bowel movements. Learn more about common causes and treatments for fecal incontinence.
When cancer is involved, leakage typically appears with other warning signs. These may include rectal bleeding, pain or pressure in the anal area, a lump near the anus, unexplained weight loss, or a noticeable change in stool shape or frequency.
Anyone with new or persistent bowel leakage, especially if it lasts more than a few weeks or comes with the symptoms above, should seek medical care. A gastroenterologist or a colorectal surgeon is the most appropriate specialist to evaluate and guide testing. Avoid self-medication for diarrhea or constipation without advice, and follow medical recommendations for screening and follow-up to keep bowel health on track.
