In the study, Dr. Lisa Newman suggests that biologic, genetic, cultural and societal factors may cause higher mortality rates in African American women with breast cancer.
To further elucidate one possible cause for the higher mortality rates, Bickell looked at the use of adjuvant breast cancer treatment—chemotherapy given after surgery to kill any remaining cancer cells—in minority women with early-stage breast cancer. Adjuvant chemotherapy greatly reduces the risk of cancer recurrence and is considered to be the standard of care for patients after breast cancer surgery. Comparing treatment in 677 women with breast cancer, Bickell found that 34 percent of blacks and 23 percent of Hispanics were not given chemotherapy after surgery as compared to only 16 percent of whites.
"Our finding highlights just how much progress could be made to eliminate cancer death and suffering by closing the gap on racial disparities in breast cancer treatment." said Bickell.
While her study was conducted in New York City, where there is an abundance of care centers, Bickel believes that part of the reason minority women receive less care is that they are less likely to have health insurance. Additionally, these women were also found to be less likely to speak with an oncologist concerning their care.
"Instituting a required oncology consultation may reduce racial disparities in care." said Bickel, who further explained that better communication between patient and doctor would also help improve care for minorities with breast cancer.
