says. "We can now tell these women that their risk for developing a
recurrence is lower than for women with ER-positive tumors."
American Cancer Society deputy chief medical officer Len Lichtenfeld, MD,
tells WebMD that the findings highlight the benefits of treating ER-negative
women with intensive chemotherapy.
"There has been some discussion about whether aggressive treatment makes

"The jury is still out on what we need to be offering women who have
