Colon cancer is cancer that develops in the tissues of the large intestine, also called the large bowel or colon. According to the American Cancer Society, over 95,000 new cases of colon cancer are diagnosed in the United States each year. The exact cause of colon cancer is unknown, but most of these cancers begin as non-cancerous growths or polyps. Over time, polyps can become colon cancer. The most common type of colon cancer is adenocarcinoma.
Not everyone experiences colon cancer symptoms, so it is important that men and women over age 50 have screening tests such as a colonoscopy. Colon polyps can be identified and removed during colonoscopy (polypectomy), preventing polyps from becoming colon cancer. Surgery to remove cancerous tissue is the preferred treatment for all stages of colon cancer and can usually cure colon cancer when found early. Some patients increase their chances of being cured by receiving additional therapy, such as chemotherapy.
