Colorectal Cancer

What is Colorectal Cancer?

Colorectal cancer develops in the colon or the rectum .The colon and rectum are parts of the digestive system, also called the gastrointestinal, or GI, system. The digestive system processes food for energy and rids the body of solid waste (fecal matter or stool).
Colorectal cancer is the third most commonly diagnosed cancer and the third leading cause of cancer death in both men and women. About 72% of cases arise in the colon and about 28% in the rectum.
