Preventing Colorectal Cancer

In some people it is clear why they developed colorectal cancer -- they inherited it; but, in most people, there is no identifiable cause. Without a known cause it makes preventing the disease tricky business. Research has suggested that aspirin may help prevent hereditary nonpolyposis colorectal cancer (HNPCC), or Lynch syndrome, an inherited form of colorectal cancer. . Other drugs such as cecloxib and sulindac, drugs used for arthritis, may help reduce the recurrence of pre-cancerous adenomatus polyps. It is also believed that eating a healthy diet with plenty of fiber, not smoking, and getting exercise may also help prevent colorectal cancer.

How Can I Prevent Colorectal Cancer?

Diet and Exercise: Experts recommend that as an initial step towards colorectal cancer prevention, people concerned about getting it should exercise and eat right. The National Cancer Institute recommends a low-fat, high-fiber diet that includes at least five servings of fruits and vegetables each day. To reduce fat in your diet, you can change your eating and cooking habits. Major sources of fat are meat, eggs, dairy products, and oils used in cooking and salad dressings. To increase the amount of fiber in your diet, eat more vegetables, fruits, and whole-grain breads and cereals.

Aspirin: It has been proposed that aspirin may stop cancer cells from multiplying. In addition, other non-steroidal anti-inflammatory drugs (NSAIDs, such as sulindac and cecloxib) may reduce the size of polyps in the colon and, therefore, the risk of colon cancer. But, this belief has not been well established and the proper dosage needed to create this potentially risk-reducing effect is not yet known. In addition, not everyone can tolerate aspirin or other non-steroidal anti-inlammatory drugs due to gastrointestinal problems, an increased risk of bleeding, medication interactions, or other medical problems. If you are concerned about your risk of developing colon cancer, you should not start taking aspirin until you discuss it with your doctor.

Screening: Most health problems respond best to treatment when they are diagnosed and treated as early as possible. To catch any abnormalities or problems early, you will need regular checkups from your doctor, including a rectal exam, fecal occult blood test, and possibly other screening tests such as a barrium enema, a flexible sigmoidoscopy, or a colonoscopy. Screening recommendations depend upon an individual's risk of colorectal cancer.
