Colon Cancer Screening: Vital for Early Detection and Survival
Colon cancer, the third most common nonskin cancer, affects about 1 in 20 Americans in their lifetime. Early detection through screening is vital, as symptoms often don't appear until the cancer has advanced. The U.S. Preventive Services Task Force (USPSTF) advises most people aged 45 to 75 to get tested.
Screening methods include stool tests, sigmoidoscopy, virtual colonoscopy, and colonoscopy. Stool tests should be done every 1 to 3 years, while colonoscopy is recommended every 10 years. Colonoscopy is preferred for those with a strong family history due to its ability to directly visualize and remove precancerous lesions. Genetic testing can also help identify inherited mutations that increase risk, especially in high-risk groups. Timely screening can significantly improve survival rates by enabling early treatment.
Colon cancer screening is crucial for early detection and improved survival rates. The best testing method and frequency depend on individual factors and should be discussed with a healthcare provider. Regular screening, starting at age 45, is recommended for most people.
