(Meredith) -- Former Pittsburgh Steelers running back DeAngelo Williams has covered the cost of 500 mammograms to honor his late mother who died from breast cancer.
Since then, Williams has covered the costs of 500 mammograms at hospitals in Pittsburgh, Memphis, Jonesboro and Charlotte.
Williams' mom died from breast cancer in 2014. She was 53. Williams said he has also lost four of his aunts to breast cancer -- all before age 50.
Williams is no stranger to supporting breast cancer awareness. According to Today, he was key to a push in 2009 to allow NFL players to wear pink cleats throughout October, which is Breast Cancer Awareness Month. In 2015, Williams also asked the NFL to allow him to wear pink on his uniform all year, but the league declined.
