Women Breast Cancer Statistics

With about 297,790 new invasive breast cancer cases expected for U.S. women in 2023 and lifetime risk reaching about 1 in 8, this page pairs the headline burden with the stark reality that incidence, outcomes, and screening performance vary widely by country and even by subgroup. You will also see how modern detection choices, from mammography to MRI, connect to survival rates like 99.3% for localized disease and why risk factors and prevention options can shift outcomes dramatically.

Breast cancer remains the most commonly diagnosed cancer among women, yet the pace of change varies sharply by country and age. In the United States, about 297,790 new cases of invasive breast cancer are expected in 2025, while U.S. incidence has stayed stable since 2012 at 128 new cases per 100,000 women each year. This mix of stability and acceleration is exactly why women’s breast cancer statistics matter, from lifetime risk and survival gaps to screening performance and prevention effects across populations.
