SACRAMENTO, Calif. (AP) — Some California women will get more information following their routine breast examinations under a state law that is now in effect. As of Monday, women with dense breast tissue must be notified of that finding after a mammogram. Health professionals say as many as 40 percent of women over the age of 40 have dense tissue, which can make it more difficult to detect cancer. Patients with dense tissue also will be told that their doctor can recommend additional screening options. The new requirements came out of a bill from former state Sen. Joe Simitian. Gov. Jerry Brown vetoed an initial proposal in 2011, but signed Simitian's revised bill in September. Similar notification laws have been enacted in Connecticut, Texas, New York and Virginia.
