Colorectal Cancer Screening
Colonoscopy
Doctors often screen people using Endoscopy , in which the entire large intestine is examined. During colonoscopy, growths that appear cancerous (malignant) are removed using instruments passed through the scope. Growths are sent to the laboratory to be tested for cancer. Some larger growths must be removed during regular surgery. Colonoscopy needs to be done every 10 years or more often in people at high risk of colorectal cancer.
