Early-onset cancer trends

Cancer incidence rates may be rising among younger adults.

In a study published in the Annals of Internal Medicine, investigators used data from the International Agency for Research on Cancer’s GLOBOCAN database to examine the trends in cancer incidence among adults aged 20 years and older across 42 countries between 2003 and 2017.

The investigators found that among the 13 cancer types included in the study, six of them demonstrated increases in the average annual percentage change in younger adults aged 20 to 49 years during the study period: thyroid cancer, renal cancer, endometrial cancer, colorectal cancer, breast cancer and leukemia. Although these cancer types also increased among older adults — with the exception of colorectal cancer — the average annual percentage changes were lower than those observed among younger adults.

The investigators hope their findings can inform public health guidelines to combat rising cancer rates among younger adults.
