The Importance of Colonoscopies in Preventing Colorectal Cancer

Colorectal cancer is one of the most common types of cancer in the United States, affecting both men and women equally. According to the American Cancer Society, it is estimated that there will be over 150,000 new cases of colorectal cancer in 2021 alone. While the thought of cancer can be daunting, there is good news: colorectal cancer is largely preventable through early detection and treatment, and colonoscopies play a crucial role in this prevention.

A colonoscopy is a medical procedure that allows a doctor to examine the lining of the colon and rectum for abnormalities such as polyps, which are small growths that can develop into cancer over time. During a colonoscopy, a flexible tube with a camera on the end is inserted into the rectum and guided through the colon. The doctor is able to look for and remove any polyps that are found, reducing the risk of colorectal cancer developing.

The American Cancer Society recommends that adults over the age of 45 undergo regular colonoscopies as a screening tool for colorectal cancer. This age may vary depending on an individual’s risk factors, such as family history of colorectal cancer or personal medical history. Most people should have a colonoscopy every 10 years, though this frequency may be increased if polyps are found during a previous screening.

While the thought of a colonoscopy may be intimidating for some, the procedure is generally well-tolerated and can be lifesaving. Many patients are sedated during the procedure, making it painless and allowing them to relax. The entire procedure usually takes less than an hour, and patients are able to return to their normal activities shortly afterward.

The importance of colonoscopies in preventing colorectal cancer cannot be overstated. Colorectal cancer often develops slowly over many years, starting as small, noncancerous polyps that can be easily removed during a colonoscopy. By identifying and removing these polyps early, the risk of developing colorectal cancer is greatly reduced.

In addition to preventing cancer, colonoscopies can also detect colorectal cancer in its early stages when it is most treatable. When colorectal cancer is caught early, the five-year survival rate is over 90 percent. However, if the cancer has spread to other parts of the body by the time it is diagnosed, the five-year survival rate drops to just 14 percent. Regular colonoscopies can help catch cancer in its earliest stages, giving patients the best possible chance at a successful outcome.

Despite the clear benefits of colonoscopies, many people are hesitant to undergo the procedure due to fear or misconceptions. However, the risks of not having a colonoscopy far outweigh the risks of the procedure itself. Colorectal cancer is the third leading cause of cancer-related deaths in the United States, and early detection through colonoscopies can help prevent many of these deaths.

If you are due for a colonoscopy or have never had one, talk to your doctor about scheduling a screening. Remember, a colonoscopy could save your life. Don’t let fear or misinformation stand in the way of your health – take charge of your colorectal health today.
