Colorectal Cancer Screening Directory
Colorectal cancer screenings are the most important factor in early detection. Most people should begin having a colonoscopy at age 50 at intervals of 10 years. In a colonoscopy, a tiny camera is used to examine the colon and rectum. If polyps are found, they can be removed during this procedure. A virtual colonoscopy uses a CT scan to create a 3D model of your colon and also reveals polyps or other problems. X-rays and blood tests may also be used to screen for colorectal cancer.
