The Senate voted to require health insurance companies to provide free mammograms and other preventive services to women. The 61-to-39 vote on health benefits for women would, in effect, override new recommendations from a federal advisory panel that said routine mammograms should begin at age 50, rather than 40, the New York Times reports. Senator Barbara A. Mikulski (D-MD) proposed the coverage requirement as an amendment to the health legislation, and said it could save millions of lives.
