Colorectal cancer (CRC) starts in the colon or rectum and is the second leading cause of cancer-related deaths in the US. Most CRC begins as a growth, called a polyp, on the lining of the colon or rectum and over time, can develop into cancer.
Through the use of colonoscopy, CRC has become one of the most preventable cancers, giving patients the power to help protect themselves from this potentially deadly disease. During a colonoscopy, physicians use a thin, flexible tube with a camera, called a colonoscope, to examine the lining of the colon and rectum. Throughout the procedure, the physician can collect biopsies of abnormal tissue and remove colon polyps, resulting in the early detection and even prevention of CRC.
