Speaking of Health: Keeping your colon healthy and cancer-free

Colorectal cancer — cancer of the large intestine and rectum — is the third most commonly diagnosed cancer in the United States. According to the American Cancer Society, there will be more than 140,000 cases of colorectal cancer this year. But there is reason for optimism as cancer screenings, lifestyle changes and added awareness can decrease your risk for colorectal cancer.

1. Screenings

Colorectal cancer often begins as small non-cancerous polyps that may become malignant over time. Colorectal cancer screenings can detect the polyps early and prevent the disease from developing.

Health care professionals recommend screenings for colorectal cancer beginning at age 50. If the disease runs in your family, a good rule of thumb is to start screenings ten years prior to your family memberís age of diagnosis. For example, if your aunt was diagnosed at 53 years old, begin your screenings at 43.

There are various screenings available, so please discuss the options with your health care provider.

2. Symptoms

The most common symptoms of colorectal cancer are:

  • Blood in the stool
  • A change in bowel habits, such as diarrhea or constipation
  • Persistent abdominal discomfort or pain
  • Unexplained weight loss

Although colorectal cancer may not produce symptoms, you should contact your health care provider if you have concerns or if you experience any of these symptoms.

3. Risks

The exact cause of colorectal cancer remains unknown, but there are proven risk factors for the disease. You can change your lifestyle to avoid certain risk factors, but there are some that you cannot prevent.

Unavoidable risk factors include:

  • Family history of colon polyps and cancer
  • Race (African-Americans are at greater risk)
  • Inflammatory intestinal disorders like ulcerative colitis or Crohnís disease

Avoidable risk factors include:

  • Obesity
  • Lack of exercise
  • Unhealthy diet
  • Smoking
  • Drinking alcohol in excess

4. Prevention

Colorectal cancer screenings are extremely important, but there are also simple lifestyle changes you can make to decrease your risk.
