Follow-Up Care for Colorectal Cancer. The primary goal of follow-up care for colorectal cancer is early detection of cancer that has returned after treatment. Follow-up care for colorectal cancer includes regular physical examinations, carcinoembryonic antigen (CEA) tests, computed tomography (CT) scans, and colonoscopy or rectosigmoidoscopy. Talk with your doctor about your risk of having the cancer come back and an appropriate follow-up care plan for you.
