In recent years, rates of colorectal cancer cases and deaths in the United States rose among young and middle-aged adults, an American Cancer Society study of colorectal cancer trends between 2000 and 2014 finds. That increase came even as rates of colon and rectal tumors and deaths dropped in people 50 and older, researchers report online March 1 in CA: A Cancer Journal for Clinicians.
Few people who are under 50 get colorectal cancer, but the incidence in this group has risen since 2000, from 5.9 new cases diagnosed in every 100,000 people to 7.2 per 100,000 in 2013. In contrast, the incidence rate for people age 50 and older was 119.3 per 100,000 in 2013. New cases are still most prevalent in people 65 and older: 58 percent of the estimated 135,430 new diagnoses projected for 2017 will occur in that age group.
