The San Francisco Chronicle (4/29, Colliver) reports that in a study “looking at the medical histories of more than 1,600 women diagnosed with breast cancer,” investigators found “that those who had breast-fed had a 30 percent lower risk of recurrence of the disease after effective treatment and tended to have less aggressive tumor types than those who had not breast-fed.” The investigators “saw improved breast-cancer outcomes among women who had breast-fed, but in addition found that those who breast-fed for six months or longer fared even better throughout the nine-year follow-up period.” The findings were published in the Journal of the National Cancer Institute.
