Think that having insurance translates into less racial disparities in the health care system? Maybe not, says a new study from Georgia. The study found that black women who were diagnosed with breast cancer were less likely than white women to receive treatment even if they have health insurance.

Researchers from HealthCore, a health care research and support company, analyzed 3000 women patients provided by Blue Cross/Blue Shield of Georgia, who were diagnosed with breast cancer. The study revealed that the increased risks in breast cancer found in black women result from hypertension, lower prevalence of hormone-positive breast cancer, lower rates of hormone therapy and later-stage diagnosis. They also concluded that black women delay medical treatment because of a lack of trust in the health care system.

According to the study, “culturally sensitive and targeted interventions must be developed to increase earlier detection of breast cancer in [blacks], increase the percentage of patients who receive hormonal therapy when it is indicated, and include management of co-morbid conditions.”
