Rectal Cancer Screening

Rectal cancer screening involves tests to detect cancer or precancerous changes in the rectum before symptoms appear. The most common screening methods include colonoscopy, where a doctor examines the rectum and colon with a flexible tube, and stool tests that check for hidden blood or abnormal DNA. Starting at age 45, regular screening is recommended, as early detection significantly improves treatment success. If abnormalities are found, further investigation may be needed. Discussing personal risk factors with a healthcare provider can help determine the best screening approach for you.
