Colon cancer facts
Colorectal cancer is a malignant tumor arising from the inner wall of the large intestine.

Most colorectal cancers develop from polyps. Removal of colon polyps can prevent colorectal cancer.
Colon polyps and early cancer may have no symptoms. Therefore regular screening is important.
Diagnosis of colorectal cancer can be made by barium enema or by colonoscopy with biopsy confirmation of cancer tissue.
Treatment of colorectal cancer depends on the location, size, and extent of cancer spread, as well as the health of the patient.
Surgery is the most common treatment for colorectal cancer.
Chemotherapy can extend life and improve quality of life for those who have had or are living with colorectal cance
Colon cancer
Colon cancer is cancer of the large intestine (colon), the lower part of your digestive system. Rectal cancer is cancer of the last several inches of the colon. Together, they're often referred to as colorectal cancers.
Most cases of colon cancer begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Over time some of these polyps become colon cancers.
Polyps may be small and produce few, if any, symptoms. For this reason, doctors recommend regular screening tests to help prevent colon cancer by identifying polyps before they become colon cancer.
