In 2013, the American Cancer Society estimates there will be 102,480 new cases of colon cancer and half will be in women. The number of cases of rectal cancer is expected to be 40,340. Over a lifetime, 1 in 19 men and 1 in 20 women will get colon cancer. The risk is higher if you have a positive family history of colon cancer or inflammatory bowel disease. It’s the second leading cause of death in both. But here is the good news – it’s preventable. That’s right. If you have a colonoscopy beginning at age 50 and regularly after that, the polyps that turn into cancer can be found and removed before colon cancer begins.

Like many cancers, the most common symptom is abnormal bleeding. Any bleeding from the rectum, especially after menopause, should cause you to call your doctor and find out why. You can also screen for colon and rectal cancer. Each year after 40 and definitely after age 50, have a rectal exam and have the stool tested for blood. This simple test is usually done in your doctor’s office and the results given to you during the exam. After age 50, it is also advisable to have a flexible sigmoidoscopy (view inside the rectum and lower colon) or colonoscopy on a regular basis to look for any cancer or precancerous growths. People with a high risk for colon cancer should be screened more frequently. If it is found before it has spread, 91% of those treated will survive five years or more.
What cancer-screening tests have you had done? What changes can you make in your diet and behavior to lower your cancer risk?
