To help prevent colorectal cancer, eat plenty of fresh fruits and vegetables; cut back on red meat and other high-fat foods, such as eggs and many dairy products. You can get the protein you need from low-fat dairy products (also a good source of calcium), nuts, beans, lentils, and soybean products. Calcium supplements have also been shown in some trials to modestly reduce the risk of colon cancer. Avoid overcooking or barbecuing meats and fish.

Men over a certain age; to screen for prostate cancer, the digital rectal exam is recommended annually in all men beginning at age 50. Men at high risk (African-American men and men with one or more first-degree relatives -- a parent or sibling -- diagnosed at an early age) should begin testing at age 45. Men at even higher risk, due to multiple first-degree relatives affected at an early age, may begin testing at age 40.
Anyone with rectal bleeding, abdominal or pelvic pain, or a change in bowel habits
Annually, if over age of 50, to check for abnormalities of the rectum and/or blood in the stool
What Happens During a Digital Rectal Exam?
Before a digital rectal exam, you will be asked to undress below the waist and drape a paper or cloth covering over your waist. Men are often examined while standing, bending forward at the waist, or lying on their side with knees bent.
The health care provider will insert a lubricated, gloved finger into the rectum and feel for tenderness, or other abnormalities. Often pressure is applied to the abdomen with the other hand to improve the ability to detect any abnormalities. The test takes only a few minutes to complete.
Women are often examined during the pelvic exam with their feet raised and supported by stirrups. The health professional then inserts a gloved, lubricated finger into the rectum. Pressure may be applied with the other hand on the lower abdomen or pelvic area to feel for tenderness or abnormalities (such as enlargement, hardness, or growths) of the organs and related tissues.
You may experience slight, momentary discomfort during the test. The procedure does not cause significant pain or any damage to the prostate.
