Colon cancer: Symptoms | Staging | Definition | Treatments

Definition - colon cancer - When polyps are discovered in a sigmoidoscopy (an inspection of the lower third of the large intestine), they are retrieved to be tested for cancer.

If a large amount of polyps are found, a more thorough examination of the entire length of the large intestine (a colonoscopy) may be recommended.

The colon and rectum are part of the large intestine (large bowel).

Colon and rectum cancers, which are sometimes referred to together as "colorectal cancer," arise from the lining of the large intestine.

When cancer arises from the lining of an organ like the large intestine, it is called a carcinoma.

Alternative Names: Colorectal cancer; Cancer - colon
