Introduction to colon cancer prevention

Comment on this

Cancer of the colon and the rectum (also known as colon cancer or colorectal cancer) is a malignant growth arising from the inner lining of the colon or rectum. Colorectal cancer is the third leading cause of cancer for both sexes in the United States. The American Cancer Society in their 2014 Cancer Facts and Figures report estimates that more than 135,000 cases will be diagnosed in 2014 and at least 50,000 deaths due to colorectal cancer will occur in 2014.

Colorectal cancer is a major cause of cancer-related deaths among men and women in the United States.

The good news is that colorectal can be both curable and preventable if it is detected early and completely removed before the cancerous cells metastasize (spread) to other parts of the body. Colorectal cancer can be prevented by removing colorectal polyps before they grow and change into cancers, or by using natural substances or man-made chemicals to prevent the colorectal polyps from changing into cancer. (Using natural substances or chemicals to prevent cancer is called chemoprevention).

Measures to prevent diseases usually fall into one of five categories of safety and effectiveness. These categories are:

  1. Measures that have scientifically-proven effectiveness and long-term safety
  2. Measures that probably are effective but may have long-term, adverse side effects
  3. Measures that probably are effective, and safe
  4. Measures that have been found to be ineffective or unsafe
  5. Measures that have no scientific basis and no studies to measure effectiveness and safety

On August 11, 2014, the FDA approved a new test for home use called Cologuard to screen for hemoglobin and abnormal (precancerous and cancerous) cells by detecting their abnormal DNA fragments. The test was proved safe and effective in a large clinical trial.

When should colon cancer screening begin?

Comment on this

Screening for colorectal cancer is one of the best ways to prevent the disease. Most screening has been done in the recent past by the invasive technique of colonoscopy. Colon cancer screening tests and procedures look for pre-cancerous or cancer cells in people who have no symptoms of disease.

Some screening procedures and tests may vary depending on a person's risk factor for colorectal cancer.

The new FDA-approved test is not invasive, less expensive and much easier to accomplish than colonoscopy but it is not a treatment procedure. However, colonoscopy can both screen for precancerous and cancerous conditions and treat many of those (by removing the suspected tissue) during a single invasive procedure.

Adults who have no risk factors for colon cancer should begin colon screening at the age of 50.
