The exact cause of
colorectal cancer is not known. Most cases begin as
small growths, or
polyps, inside the intestine.
colorectal cancer is not detected and removed, it invades and destroys nearby
tissues and may spread to other parts of the body. Even after treatment that seems successful, colorectal cancer may spread or come back.
Getting regular checkups and colon cancer screening is the best way to prevent colorectal cancer. Finding and removing colon polyps helps prevent colon cancer. In addition, colon cancer screening helps find cancer early, making a cure more likely.
