Insured black women and uninsured white women waited more than twice as long to be given a definitive breast cancer diagnosis than insured white women.
Lack of health insurance slowed the speed of diagnosis among white patients, but having insurance did not lead to quicker diagnosis among insured black women.
Overall, black patients waited twice as long as white patients to begin treatment after breast cancer diagnosis.
"We thought having health insurance would even the field and that insured black women would have had the same rate of evaluation as insured white women, but that was not the case in our study," Heather Hoffman, an assistant professor of epidemiology and biostatistics at the George Washington University School of Public Health and Health Services, said a news release from the school.
