Colon, Rectum and Anus Cancers

In 2024, it is estimated that 106,590 Americans will be diagnosed with colon cancer. Colorectal cancer is the third most commonly diagnosed cancer in men and women. 46,220 men and women will be diagnosed with rectal cancer. In addition, about 10,540 people will learn they have anal cancer. Patients with these types of cancers often benefit from radiation therapy as part of treatment. Some cancers involving the bowel run within families (hereditary colorectal cancers). It is important to discuss your diagnosis with family members so they can decide with their doctors whether they need to be screened for colorectal cancers. This is especially important if you were diagnosed with a colorectal cancer before age 50 or if there are several other types of cancers that run in your family.
