A member asked:

Bright red rectal bleeding stopped 2.5 years ago -- had sigmoidoscopy then and didn't see anything. does cancer usually continue to bleed?

3 doctors weighed in across 2 answers

Maybe not: Bright red blood like this usually comes from something actively bleeding way down low in your colon or rectum. This includes hemorrhoids or even diverticulosis. You seem pretty young for these things, and I am reassured you had a normal sigmoidoscopy. However, since the symptoms have returned, it's probably best to have the GI doctor see you again to be sure.

Hemorrhoids: Bright red blood may signify a hemorrhoid and that was self limiting. The sigmoidoscopy showed that no cancer was present in the sigmoid colon. Your doctor wanted to know your family history of cancer and cancer would continue to have episodes over 2+ years. Talk with your doctor to discuss your concerns. People need a screening colonoscopy at 50 or sooner with a risk factor.
