Across St. Louis, breast cancer is not striking everyone equally. Black women are being diagnosed later, starting treatment more slowly and, as a result, dying more often, especially at younger ages. Researchers say the pattern points to a stubborn reality: the region has machines and medical expertise, but too many people are blocked from using them.
As reported in a regional analysis that found Black women ages 35 to 44 are roughly four times more likely to die of breast cancer than white women in the same age group, Gateway to Hope worked with the City of St. Louis and St. Louis County health departments, the University of Illinois Chicago School of Public Health and the Missouri Foundation for Health to map the problem. The report is described as the first regional effort to connect screening utilization, late-stage diagnosis and mortality at the ZIP-code level.
Local capacity, uneven use
Gateway to Hope’s capacity survey shows that St. Louis City and County are not short on technology. The region has widespread access to modern imaging, including 67 digital breast tomosynthesis (3D) units, yet providers are using only a fraction of their available screening hours. According to Gateway to Hope, providers reported about 132,515 screenings in 2024, compared with roughly 322,562 women who were recommended for annual mammograms, and average utilization across reporting sites hovered near 49 percent.
Access barriers compound the problem
Investigators and community leaders point to practical obstacles, not missing machines. Lack of reliable transportation, childcare gaps, limited evening and weekend appointments and medical mistrust all keep people from getting screened. Women in parts of North County may face more than an hour of public-transit time just to reach a roughly 20-minute mammogram, and late-stage diagnoses and treatment delays are concentrated in largely Black, low-income ZIP codes.
Fixes that could move the needle
Gateway to Hope also found several safety-net clinics and other sites with some of the most unutilized capacity, suggesting that targeted outreach, extended hours and mobile or community-based screening could pull more people into care. Washington University is testing outreach and navigation strategies in a randomized study aimed at boosting mammography among Black women, according to its ClinicalTrials.gov listing, and national analyses from Susan G. Komen place St. Louis among metros with some of the worst Black-white mortality gaps and recommend patient navigation, financial supports and quality-improvement work to close them.
Public-health officials and advocates say the message is blunt: if underused machines and uneven schedules are a big part of the problem, then practical fixes such as ride programs, evening clinics, patient navigators and targeted outreach could turn capacity into care. The question for St. Louis now is whether hospitals, clinics and policymakers can move quickly enough to cut late-stage diagnoses and the deaths that follow.
