The incidence of colorectal cancer is increasing among the young adult population while decreasing among adults in the screened population, according to new research data.
Aiming to assess CRC incidence in young adults aged 20 to 39 years and to identify subgroups with higher risk, researchers extracted data from the California Cancer Registry. They analyzed 231,544 incident CRC cases diagnosed from 1988-2009, of which 5,617 occurred in young adults. They stratified incidence rates by age, major race/ethnicity population (71% Caucasian, 7% African American, 12% Hispanic and 10% Asian/Pacific Islander), gender and tumor location, and calculated biannual percent change (BAPC) in CRC incidence throughout the study period.
