At-home colon cancer screening tests have grown increasingly popular due to their convenience and non-invasiveness. However, colonoscopies remain the gold standard for colon cancer screening – which is why MedBen WellLiving programs typically recommend them every 10 years beginning at age 45.
While at-home tests can detect blood or genetic markers associated with cancer, they may not always be as accurate as a colonoscopy. At-home tests can produce false positives or negatives, leading to unnecessary anxiety or missed diagnoses. Conversely, colonoscopies are highly sensitive and provide a clearer, more definitive diagnosis.
Other key benefits of colonoscopies over at-home screenings include:
Comprehensive Detection. Colonoscopies allow direct visualization of the entire colon, detecting cancer, polyps, and other abnormalities that at-home tests might miss.
Ability to Remove Polyps. The physician can remove polyps during the procedure, preventing potential cancer development.
Immediate Results and Follow-Up. Results are immediate, and any necessary interventions, like biopsies or polyp removal, can be performed on the spot.
Comprehensive Risk Assessment. The physician provides a comprehensive assessment of colon health, identifying other gastrointestinal issues beyond cancer risks.
Better for People with Higher Risk. Colonoscopies are better suited for high-risk individuals, offering a more thorough evaluation compared to at-home tests.
In short, colonoscopies offer a more comprehensive, accurate, and preventative approach compared to at-home colon cancer tests. But if you’re unsure, talk to your family doctor about the right option for you.
