LOS ANGELES, Aug. 16 (Xinhua) -- Cancers among younger Americans under 50 years of age are increasing at an alarming rate, with gastrointestinal cancers climbing at the fastest rates, according to a new study published on Wednesday.

       In this cohort study of 562,145 people with early-onset cancer in the United States from 2010 to 2019, the incidence rates of early-onset cancers increased substantially over this period.

       Although breast cancer had the highest number of incident cases, gastrointestinal cancers had the fastest-growing incidence rates among all early-onset cancers, according to the study published in JAMA Network Open.

       These data may be useful for the development of surveillance strategies and funding priorities, said the study.
