What Is Colorectal Cancer?

Colorectal cancer starts in the colon or rectum. The risk of colorectal cancer goes up as you get older, and if you eat a meat-heavy diet, smoke, or have a family history of the cancer. Colorectal cancer symptoms include pain, blood in the stool, and a change in bowel habits. Routine screening for colorectal cancer is recommended starting at age 50—or even sooner for those with risk factors.
