I am 19 and have blood in my stool, it

Patient: I am 19 and have blood in my stool, it is a reasonable amount and has become a regular occurrence, although it doesn’t hurt occasionally it does feel like a little tear in the anus. I know what it could be but i wanted to know what it is likely to be, there is a history of colon cancer in my family but from over 40 year olds.

Symptoms: Blood in stool
