Breast cancer more lethal in black women

According to a recent Reuters article, breast cancer appears to be more lethal in Black women according to the results of a new study. Researchers had thought that obesity differences between Black and White women might explain the breast cancer survival difference between the two groups five years after the initial diagnosis (78% Blacks to 90% Whites). While this was not proven, researchers believe that differences in tumor biology as well as health care access could be at play.
