Patients United Now, a project of the Americans for Prosperity Foundation, released a new national TV ad today airing on Fox News Channel, CNN and Headline News today through Thursday.

“Early detection saved my life,” Walsh says in the ad, warning that government panel guidelines about delaying mammograms until age 50 could be dangerous. “If I had followed the new government guidelines on mammograms, my cancer would have spread undetected, and my chances of survival would have been reduced.”
