Double amputee beats breast cancer diagnosis

Yvonne Llanes already knew her strength -- and her community.

Even before her stage two breast cancer diagnosis in 2020, Yvonne Llanes knew her strength -- and her community.

Llanes, who was first introduced to "World News Tonight" in 2017, had lost both of her legs nearly 16 years ago in a freak accident. For a decade, Llanes was confined to a wheelchair.

But, in 2017, she had made a promise to herself -- and her late father -- to walk again.

"I was just depressed. I was sad. I was mad at the world and I wanted my life back. I wanted my legs back," Llanes told "World News Tonight" in 2017.
