Stop Colon Cancer Before It Stops You!

Colon cancer, also known as colorectal cancer, is preventable, but it is the second leading cause of cancer deaths in the United States. Colon cancer affected over 145,000 people in 2006, and 56,000 of those will die from it. However, with early screening and treatment, the survival rate is 90%.

What is colon cancer?
Colon cancer often begins with a polyp - a small growth - on the lining of the colon, rectum or part of the digestive tract. Finding and removing polyps can prevent cancer from ever getting a chance to develop.

Whom does it affect?
Colon cancer primarily affects men and women over age 50. However, people with a family history of cancer need to be tested before age 50 and more often. Only 25% of colon cancer occurs in people with a family history; 75% of cases occur in people with no risk factors. Signs of colon cancer include: bleeding from rectum, crampy pain, change in shape of stool, blood in stool.
