Black women appear to have a more difficult time than white women recovering from breast cancer. Doctors at the Harvard school of public health followed nearly 20,000 women with stage 1 to stage 3 breast cancer over nearly 7 years. Non-hispanic black women had a 48%t higher risk for breast cancer death in the first three years after diagnosis compared to white patients. The difference was most striking for those with estrogen receptor-positive tumors. Those cancers are often considered treatable. More studies are being conducted to determine exactly why.
