Colon Cancer overview

This is a good article for knowledge of what exactly colon cancer is.



Overview

Colorectal cancer, also called colon cancer or rectal cancer, is cancer of the large intestine or bowel. Most cases start from polyps on the lining of the intestine. Polyps are small, mushroom-shaped growths, which most of the time are harmless. However, certain kinds, called adenomatous polyps, have the potential to become cancerous.

Colon cancer is among the most common types of cancer, with more than 104,000 new diagnoses each year. An additional 40,000 people are diagnosed annually with cancer of the rectum. Genetics plays a role: Up to 1 in 4 people with colon cancer have family members who have had the disease. Lifestyle is also a factor: People who aren't physically active and who eat a high-fat or low-fiber diet are at increased risk.
