Colorectal Cancer

Colon cancer and rectal cancer are collectively known as colorectal cancer, the third most common cancer in both men and women. The colon and the rectum are parts of the large intestine, which makes up the lower part of the body’s digestive system. During digestion the colon absorbs water and nutrients from food and stores waste matter. Colorectal cancer often starts with a growth called a polyp, which forms on the inner wall, and can become cancerous over time.
