Colorectal CancerColorectal cancer includes cancers of both the large intestine (colon), the lower part of your digestive system, and the rectum, the last 8 to 10 inches of the colon. 
Most colon and rectal cancers begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Over time some of these polyps become cancerous. Polyps may be small and produce few, if any, symptoms, so it's important to get regular screening tests to help prevent colorectal cancer. If signs and symptoms of cancer do appear, they may include a change in bowel habits, blood in your stool, persistent cramping, gas or abdominal pain. Colorectal cancer is the second-leading cause of cancer-related deaths in the United States. Only lung cancer claims more lives. Each year, more than 135,000 Americans are diagnosed with colorectal cancer and 56,000 die. Still, there's good news about colorectal cancer. Screening tests, along with a few simple changes in your diet and lifestyle, can dramatically reduce your overall risk of developing the disease. |
