INDIANAPOLIS, Ind. — The NFL and the Indianapolis Colts are raising awareness of breast cancer screenings during Crucial Catch Day.

Colts long snapper Matt Overton replaced CBS4’s Debby Knox on the anchor desk Tuesday as she shared her story about getting a mammogram recently, and what she learned about new technology being used.

First, Overton talked about his grandmother, who is a breast cancer survivor.

She was diagnosed about eight years ago. She went through chemotherapy and dealt with the complications that come from that.

"When you see a family member go through something difficult like that, the family bands together," he said. "She's the backbone of our family and she means a lot to me. To see her go through that and to see her attitude--it was nothing but positive. She really inspired me and our entire family."

Overton also shared a story that men should pay close attention to.

He met a man named John as the Colts were doing a visit at the IU Simon Center. John was going through chemotherapy after being diagnosed with breast cancer. They quickly became friends.

Last year, John passed away.

"(Breast cancer) doesn't discriminate against anybody," said Overton. "Nearly 2,600 men get diagnosed with it every year."

He said everyone who knew John knew he was a fighter.

"Cancer is cancer. It's something that John embraced head-on and he showed tremendous character and determination throughout the fight," he said.
