Early Detection is Key: Screening for Colon Cancer

Dr. Tyler Buckley noted that colon cancer, also known as colorectal cancer, is the third most commonly diagnosed cancer and the second leading cause of cancer death in both men and women. Yet, with early detection through screening, it is one of the most preventable forms of cancer. This brings us to an essential question: when should one get screened for colon cancer?

The American Cancer Society (ACS) recommends that people at average risk of colon cancer start regular screening at age 45. This can be done through various methods such as colonoscopy, flexible sigmoidoscopy, or stool-based tests. Depending on the specific test and your individual results, the frequency of subsequent tests may vary.

However, it's essential to understand that these are recommendations for those at average risk. Individuals with a family history of colon cancer or other high-risk factors might need to start screening earlier. In particular, if you have a first-degree relative (parent, sibling, or child) who had colon cancer or certain types of polyps before the age of 60, or two first-degree relatives diagnosed at any age, it's recommended to start colon cancer screening at age 40, or ten years before the youngest case in your immediate family.

Moreover, individuals with inherited syndromes like familial adenomatous polyposis (FAP) or Lynch syndrome (hereditary non-polyposis colorectal cancer, or HNPCC) should undergo screening even earlier, sometimes even during their teenage years. Personal history of inflammatory bowel disease (IBD) such as Crohn's disease or ulcerative colitis also places individuals at higher risk, necessitating earlier and more frequent screening.

Choosing the right screening test depends on individual preferences, medical history, and accessibility. A colonoscopy is the most comprehensive test as it allows the doctor to inspect the entire colon and remove polyps during the same procedure. Stool-based tests, on the other hand, are non-invasive but need to be done more frequently.

Early detection is critical in managing and preventing colon cancer. Knowing when to get screened is the first step towards a healthier life. While general guidelines provide a roadmap, it's essential to discuss your specific circumstances and risks with a healthcare provider. Remember, proactive measures can save lives.
