So a colonoscopy is required in any one above the age of 50 in order to reduce the risk of colon cancer. Colon cancer screening is actually the only screening that prevents cancer. Other screenings catch cancer early, but we don't want to catch cancer. We actually want to prevent it altogether. So if you do your screening procedures at the right time, your risk of subsequently getting colon cancer go down to almost zero. Colonoscopies are a life-saving tool. They are the only screening tool that we can do to prevent cancer. We are able to remove polyps before they ever grow and become cancerous and caused major complications in patients. It is something that you should tell your parents to do if they're above the age of 50 or you should do yourself if you're above the age of 50. Speak to your physician, get a consultation with a gastroenterologist. It is an extremely safe procedure. It is a painless procedure and you won't regret it after you do it.
