The Importance of Colonoscopies

If you’re approaching 45, your doctor may advise you to schedule a colonoscopy. This simple outpatient procedure screens for abnormalities that may be indicative of colorectal cancer. Here’s why undergoing this procedure is important, even if you feel perfectly fine.

Colon cancer is highly treatable with early intervention. The disease usually only manifests symptoms in the later stages, so a preemptive screening is the only way to get a prompt diagnosis.

Undergoing periodic colonoscopies will allow your doctor to identify and remove any abnormal growths or polyps in a timely manner. While these growths may not be causing any noticeable problems, they may become cancerous if ignored.

The American Cancer Society advises healthy adults to start getting colonoscopies at around 45. This is because colorectal cancer is most common in older individuals. Almost 70% of all cases diagnosed are in those who are over 65, and 40% are in those over 75.

Healthy adults are advised to undergo a colonoscopy every 10 years between the ages of 45 and 85. Those over the age of 85 don't have to continue with screenings.

If you're considered at high risk of colorectal cancer, your doctor may advise you to start screenings before turning 45. You may also be instructed to get colonoscopies more frequently than once every 10 years.

People are considered at high risk if they have a family history of colon cancer, a personal history of certain types of polyps, a personal history of inflammatory bowel disease, or a hereditary colorectal cancer syndrome. Having received radiation to the abdomen or pelvic area to treat prior cancer also increases risk.
