Here is the data: From 2005-2009, the median age at diagnosis for cancer of the colon and rectum was 69 years of age3. Approximately 0.1% were diagnosed under age 20; 1.1% between 20 and 34; 4.0% between 35 and 44; 13.4% between 45 and 54; 20.4% between 55 and 64; 24.0% between 65 and 74; 25.0% between 75 and 84; and 12.0% 85+ years of age.
See your doctor cancer is not the only cause of rectal bleeding.

See a doc: Tyree - you have numerous questions regarding this, which is fine, but it does indicate that you are genuinely concerned about this.
Yes - a 22 year old can have colon cancer, but it is much less frequent. When somebody at age 22 has colon ca, they usually have a family history that would clue in to it.
Given your level of concern, visit a GI doc to discuss further in person.
