Breast Cancer Awareness Month is in full effect and former NFL running back DeAngelo Williams is still dedicated to fighting the disease.

Williams, who played for the Carolina Panthers and Pittsburgh Steelers, started covering the cost of mammogram screening for women in 2015 through his nonprofit organization, The DeAngelo Williams Foundation.

Since then, the foundation has covered the cost of over 500 mammograms at hospitals in Pittsburgh, Memphis, Jonesboro, Ark., and Charlotte, N.C.

Williams is a staunch supporter of breast cancer awareness. In 2014, his mother Sandra Hill died from breast cancer when she was just 53. Williams also lost his four aunts to the disease, all before the age of 50.

This is dedicated to my mom, my aunts & women everywhere affected by Breast Cancer. I love you. #WeAreInThisTogetherhttps://t.co/bAwaanlfzV

Williams began sponsoring the free mammogram screening in honor of his mother through the “53 Strong for Sandra” program.

At each event, the foundation sponsors mammograms for 53 women. The foundation eventually hopes to host a free mammogram screening event in every state.

“DeAngelo wants to ensure that no woman (or man) fights breast cancer alone,” Risalyn Williams, his wife and executive director of The DeAngelo Williams Foundation, told TODAY via email.

This is such a beautiful gesture and we’re sure Ms. Sandra would be proud of her son.

Don’t forget to get a mammogram to help prevent breast cancer — and take a friend.
