Longer chemo better for early-stage node-positive breast cancer

Women with early-stage breast cancer—estrogen-negative or positive—with lymph node involvement benefit more from a 24-week regimen of chemotherapy than from 12 weeks of treatment. Interestingly, women who went into “chemopause”—chemotherapy-induced menopause—during treatment did better than women who did not. Read Web MD’s story on the research here. The research was published in the June 3 2010 New England Journal of Medicine.
