We used data from the US Cancer Statistics database to determine trends in cancer incidence, stratified by age, race, and ethnicity, among women aged 20 years or older during an 18-year study period (2001-2018). We limited analysis to cancers associated with 5 modifiable risk factors: tobacco use, excess body fat, alcohol consumption, insufficient physical activity, and human papillomavirus infection. The incidence of cancers associated with obesity have risen, particularly among women aged 20 to 49 years (vs ≥50 y) and among Hispanic women. Strategies that address obesity rates in these populations may help decrease cancer risk.
