Colon Cancer
An estimated 150,000 people were diagnosed with cancers of the colon or rectum in 2009, according to the American Cancer Society (ACS). Though the cancers will claim nearly 50,000 lives in the United States, more people are surviving their battles. Learn more about colorectal cancers with the Colon Cancer Web Guide.
What Is Colon Cancer?
The colon is part of our digestive system, and one of the last stops for food before it enters the rectum and leaves the body. Colon cancer occurs when cells, for reasons not entirely understood, grow abnormally in the colon to form masses and tumors that affect the body.
