    Study: Estrogen Treatment Risky

    ln this photo taken Wednesday Sept. 14, 2011, Dr. Karen Lindsfor, a professor of radiology and chief of breast imaging at the University of California, Davis Medical Center, examines the mammogram of a patient with heterogeneously dense breast tissue,  in Sacramento, Calif. Lindfors opposes a measure approved by the state Legislature earlier this month, that would require health facilities performing mammograms to notify patients with dense tissue that they may want to receive additional screenings.  Lindfors is among those doctors who say there was insufficient evidence to support the idea that additional screenings  would detect cancers earlier. (AP Photo/Rich Pedroncelli)

Doctors recommend taking the lowest possible hormone dosage for women treating menopause.
