Colon cancer forms in the tissues of the colon as the longest part of the large intestine. Most colon cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids).

Rectal cancer forms in the tissues of the rectum -the last several inches of the large intestine closest to the anus.

Cases of colon cancer in 2008 totalled 108,070 and colon –rectal combined was 40,740. Deaths from colon and rectal cancer in the U.S. numbered 49, 960. For more detailed information on Colon and Rectal Cancer please log on to http://www.cancer.gov/cancertopics/types/colon-and-rectal.
