Occasional constipation, occasional mild abdominal discomfort, and ocassional anal bleeding (red not black) Through the span of the last 6 months there has been maybe 5-6 bleedings. I just discovered what could be a small external polyp after a bowel movement with bleeding. The bleeding is not in the stool, I believe it is coming directly from the anus. In the past 2 weeks I have had mild abdominal discomfort that has lasted a while and then went away without a bowel movement. I am afraid it could be cancer but I am only 18 years of age. Please help (I have a picture of the small could-be polyp
