The Importance of Routine Colonoscopy Screenings

By Christine Cameron, M.D., Primary Care, Buffalo Medical Group

March is Colon Cancer Awareness Month, a time dedicated to highlighting the importance of early detection and prevention of colorectal cancer. Colon cancer is the second leading cause of cancer-related deaths in the United States, but with routine screenings, it is highly preventable and treatable. One of the most effective tools for early detection is the colonoscopy.

Current Screening Guidelines

The U.S. Preventive Services Task Force (USPSTF) and the American Cancer Society (ACS) recommend that adults at average risk for colon cancer begin routine screenings at age 45. Individuals with a family history of colon cancer or other risk factors, such as inflammatory bowel disease, may need to start screenings earlier. Colonoscopy screenings should be performed every 10 years for those with normal findings, while individuals with polyps or other abnormalities may require more frequent monitoring.

Early Detection and Survival Rates

Early detection through routine colonoscopies significantly improves survival rates. When detected at an early stage, the five-year survival rate for localized colon cancer is approximately 91%. However, if the cancer has spread to distant organs, the survival rate drops to about 14%. This stark contrast underscores the importance of routine screenings, as colonoscopies can identify and remove precancerous polyps before they develop into cancer.

Colonoscopy Preparation and Procedure

A colonoscopy is a procedure in which a physician uses a thin, flexible tube equipped with a camera to examine the lining of the colon for abnormalities. Proper preparation is crucial to ensure a clear view of the colon. Preparation typically involves a clear liquid diet the day before the procedure and drinking a prescribed laxative solution to cleanse the colon. During the procedure, the patient is sedated for comfort. The physician carefully examines the colon and removes any polyps or suspicious growths for further testing. The procedure typically takes 30 to 60 minutes, and most patients can resume normal activities within a day.

Ask Your Primary Care Doctor

Routine colonoscopies are a vital tool in the fight against colon cancer. By following screening guidelines and prioritizing early detection, individuals can significantly reduce their risk of developing and dying from this disease. During Colon Cancer Awareness Month, ask your primary care provider for a referral and take the opportunity to schedule your screening or encourage a loved one to do the same—it could save a life.
