March is National Colorectal Cancer Awareness Month. Colorectal Cancer, or CRC, is highly treatable if found in the early stages. Despite this, CRC is the third deadliest cancer in the United States. People are encouraged to begin screening for CRC at the age of 45. Screenings can expose the warning signs of CRC and allow doctors to take action to prevent the disease from developing. CRC is a disease in which cells in the colon or rectum grow out of control. Sometimes, abnormal growths, called polyps, form in the colon or rectum. Over time, some polyps may develop into cancer.
