JOPLIN, Mo. - Missouri Governor Jay Nixon signed a bill into law on Tuesday, which should improve breast cancer detection.
Senate Bill 639 requires mammography facilities to provide women with information about dense breast tissue. Dense breast tissue can hide abnormalities that would otherwise be identified in mammograms.
According to the National Institutes of Health, women who have a high percentage of dense breast tissue are a greater risk of developing breast cancer.
Nixon signed the bill at Freeman Hospital West in Joplin.
