About Colorectal Cancer
Colorectal cancer is a growth that begins in the colon or rectum. These areas are part of the large intestine. Doctors believe colorectal cancer usually develops from benign growths called adenomatous polyps. Polyps can become cancerous unless caught early by routine screening tests.
In the United States, colorectal cancer is the fourth most common cancer in both men and women. Survival rates for colorectal cancer range from 10% to over 90% when the cancer is found and treated early.
