Uterus Cancer Statistics

See why uterine cancer risk can change dramatically across biology and behavior, from Black women facing 2.5 times the age adjusted incidence of White women in US SEER data (2015–2019) to obesity and diabetes raising endometrial cancer risk while combined oral contraceptives, physical activity, and even smoking are linked to lower risk. You will also find treatment trial outcomes that are reshaping care, since immunotherapy options for dMMR or MSI-H endometrial cancer have moved from promising signals to measurable improvements in progression free survival.
