About Colorectal Cancer
Colorectal cancer is the third most common cancer and the second-leading cause of cancer death in the United States. In the United States there were 146,970 estimated cases and 49,920 reported deaths for both colon and rectal cancer in 2009. Screening is an important means of detecting the disease early, when the chances of cure are highest. Screening also allows for the detection and removal of potentially precancerous growths, called polyps, preventing the cancer from developing.
