The proportion of people diagnosed with early-onset cancer increased by about 79% around the world between 1990 and 2019, according to an analysis of outcomes across 29 types of cancer. Deaths from cancer increased by about 28%—an absolute increase of about 230 000 deaths worldwide—among people younger than 50 years during that period.
Early-onset breast, tracheal, bronchus and lung, and stomach and colorectal cancers contributed to the greatest number of deaths and the most disability in 2019. Rates of early-onset nasopharyngeal and prostate cancer increased the fastest.
