Breast Cancer Awareness Month is a reminder of what progress looks like and what still falls through the cracks. With an estimated 43,700 breast cancer deaths expected in the United States in 2024 alongside a large screening gap where 27% of eligible women do not receive a mammogram, the contrast is hard to ignore. This post pulls together the latest statistics on diagnosis, risk, prevention, screening behavior, and outreach so the numbers make sense together, not in isolation.
Key Takeaways
- 22% of breast cancers are diagnosed at a regional stage
- 34% of women are screened for breast cancer with a mammogram within the recommended interval (US, 2020 survey-based measure)
- 21% of breast cancers are estimated to be associated with germline pathogenic variants (BRCA1/BRCA2 and other high/moderate risk genes combined; synthesis estimate)
- 20.9% of all new cancer cases in women are breast cancer (US, 2024 projection share)
- 281,550 new breast cancer cases are estimated in the United States in 2021
- 42% of US women agree that social media helps them learn about breast cancer (survey-based)
- 5.5 million people reached via Komen Race for the Cure campaign communications in 2023 (media reach estimate)
- 73% of marketers reported using cause marketing campaigns in 2024, enabling awareness efforts for health causes (survey-based industry statistic)
- $8.2 billion global market size for breast cancer therapeutics in 2023 (estimate)
- A 10% increase in mammography screening coverage is associated with a measurable reduction in breast cancer mortality (meta-analysis estimate)
- Medicare covers screening mammography annually or biennially for eligible beneficiaries under national coverage determination (coverage policy)
- USPSTF recommends screening mammography for women aged 40–74 every 2 years (Grade B for ages 50–74 and individualized for 40–49)
- 43,700 estimated breast cancer deaths in the United States in 2024.
- 76% of women aged 50–74 in the United States were up to date with recommended mammography screening in 2021.
- 69.2% of women aged 50–74 in the United States received a mammogram within the past 2 years (behavioral indicator from BRFSS, 2021).
With only about half of eligible women screened, better awareness and mammography could save lives.
