Abstract Background Little is known regarding the association between insurance status and treatment delays in women with breast cancer and whether this association varies by neighborhood socioeconomic deprivation status. Methods In this cohort study, we used medical record data of women diagnosed with breast cancer between 2004 and 2022 at two Georgia‐based healthcare systems. Treatment delay was defined as >90 days to surgery or >120 days to systemic treatment. Insurance coverage was categorized as private, Medicaid, Medicare, other public, or uninsured. Area deprivation index (ADI) was used as a proxy for neighborhood‐level socioeconomic status. Associations between delayed treatment and insurance status were analyzed using logistic regression, with an interaction term assessing effect modification by ADI. Results Of the 14,195 women with breast cancer, 54% were non‐Hispanic Black and 52% were privately insured. Compared with privately insured patients, those who were uninsured, Medicaid enrollees, and Medicare enrollees had 79%, 75%, and 27% higher odds of delayed treatment, respectively (odds ratio [OR]: 1.79, 95% confidence interval [CI]: 1.32–2.43; OR: 1.75, 95% CI: 1.43–2.13; OR: 1.27, 95% CI: 1.06–1.51). Among patients living in low–deprivation areas, those who were uninsured, Medicaid enrollees, and Medicare enrollees had 100%, 84%, and 26% higher odds of delayed treatment than privately insured patients (OR: 2.00, 95% CI: 1.44–2.78; OR: 1.84, 95% CI: 1.48–2.30; OR: 1.26, 95% CI: 1.05–1.53). No differences in the odds of delayed treatment by insurance status were observed in patients living in high‐deprivation areas. Discussion/Conclusion Insurance status was associated with treatment delays for women living in low‐deprivation neighborhoods. However, for women living in neighborhoods with high deprivation, treatment delays were observed regardless of insurance status.
