Colon and rectum : Cancer Screening
Colon cancer screening can detect polyps and early cancers in the large intestine. This type of screening can find problems that can be treated before cancer develops or spreads. Regular screenings may reduce the risk for death and complications caused by colorectal cancer.
Different modalities of screening are – FOBT (stool test ), sigmoidoscopy, colonoscopy. It is recommend that people at average risk of colorectal cancer get screened at regular intervals beginning at age 45 or 50.
People who are at increased risk of colorectal cancer because of a family history of colorectal cancer or documented advanced polyps or because they have inflammatory bowel disease or certain inherited conditions (such as Lynch syndrome and familial adenomatous polyposis) may be advised to start screening earlier and/or have more frequent screening.
