In brief: Blockage, Bleeding

The most common symptoms associated with colon cancer include (cramping) abdominal pain, a change in bowel habits ("pencil-thin stools"), bloody bowel movements, weakness/fatigue, and/or weight loss.
The goal, of course, is to diagnose colon cancers before symptoms develop; i advise colonoscopy at age 50, or earlier if there is a family history.

In brief: Blood in stool

Common symptoms of colorectal cancer include blood in the stool, narrowing of the calibre of stools (pencil-thin stools), abdominal cramping or bloating and weight loss.
Unfortunately, by the time colon cancer causes symptoms it is often advanced which is why it's so important to get screening colonoscopy starting at age 50' or younger for higher risk patients.

In brief: They vary widely

Probably the most common symptom is no symptom at all.
However, some people may present with anemia, bleeding in the stool, all the way to an obstructing colon mass. The symptoms vary widely, but the take-home message is to get the appropriate cancer screening. For most, this is a screening colonoscopy at age 50.
