Colorectal screening is a medical process used to detect early signs of colorectal cancer and other conditions affecting the colon and rectum. It typically involves tests such as colonoscopy, sigmoidoscopy, or stool tests. These screenings are recommended for individuals starting at age 45, or earlier for those with a family history of colorectal cancer. Early detection through colorectal screening can significantly improve treatment outcomes. If abnormalities are found, further tests or procedures may be necessary. Regular screenings can help prevent cancer by identifying and removing polyps before they develop into cancerous growths.
