Colon cancer is cancer of the large intestine (colon), the lower part of the digestive system. Rectal cancer is cancer of the last six inches of the colon. Together, they're often referred to as colorectal cancers. In the United States, it is the fourth most common cancer in men and women.
Symptoms can include blood in the stool, narrower stools, a change in bowel habits, and general stomach discomfort. However, colon cancer can strike without symptoms, so screening is important. Everyone who is 50 or older should be screened for colorectal cancer. This may include blood fecal tests, colonoscopy, and review of family history. While most colon polyps are benign, some do become cancerous.
Treatments include surgery, radiation, and/or chemotherapy.
