Since end-July, I have been experiencing on and off rectum bleeding every few weeks. Bright red blood is visible when I wipe, but not in the stools. The amount of blood is usually around a 20c coin (or less) and does not seep through the toilet paper. The 1st occasion lasted a week, and was painful. I supposed it was anal fissure since it hurted badly.

However, the subsequent occurrences lasted only a day or two; sometimes it hurts and sometimes it doesn’t. More recently, I saw blood along with a burning sensation after bowel motion and attributed it to spicy meal. 3 days back I saw blood again despite having a normal, painless bowel motion.

I’m particularly worried about colon cancer. I’m turning 23 soon and had an aunt who died from colon cancer. May you advise?
