evidence: This trend is largely affected by the aging and growth of the population and by a rise in diagnoses of 6 of the 10 most common cancers—breast, prostate, endometrial, pancreatic, kidney, and melanoma. (The other 4 top 10 cancers are lung, colon and rectum, bladder, and non-Hodgkin lymphoma.) [...] What might be most striking about the rising incidence is that it’s affecting increasingly younger people. [...] The proportion of people under age 50 (sometimes referred to as younger adults) diagnosed with cancer dropped from 15% to 12% because of their shrinking representation in the general population (from 74% to 64%). Interestingly, though, they were the only one of the three age groups with an increase in overall cancer incidence from 1995 to 2020.
