In a recent study published in The Lancet Public Health , researchers assessed cancer incidence and mortality trends in the United States (US). Previously, the authors reported an increased incidence of eight cancers over time in successively younger birth cohorts in the US. Besides, people born between 1965 and 1980 might have increased incidence rates of all leading cancers combined and specific cancers, such as colorectal, kidney, thyroid, leukemia, and uterine corpus.

However, a comprehensive analysis of trends in cancer incidence and mortality by year of birth or birth cohort is lacking for contemporary generations.

They acquired incidence data from the North American Association of Central Cancer Registries for 34 cancers diagnosed at ages 25–84 between 2000 and 2019. Data on mortality were obtained from the National Center for Health Statistics; mortality analysis was restricted to 25 cancers. Population estimates were acquired from the US Census Bureau.

Cases were classified according to the International Classification of Disease Oncology and into molecular, histological, and anatomical subtypes. Birth cohort trends in cancer rates were evaluated using age-.
