GMA saved the life of ABC News Correspondent Amy Roback by sending her on assignment to get her first mammogram at age 40. The life-saving idea was for a Going Pink Day in October. 

Good Morning America celebrated Friday morning with ABC News Amy Roback's new victory over breast cancer. 

Roback, now 41, got her first mammogram on live television for GMA's Goes Pink day in October. It all began when Roback's colleague ABC News' Robin Roberts, a breast cancer survivor, pushed the then 40-year-old to get her first mammogram.

Weeks later the mother of two girls and three step-sons got the terrible news.

" I would have considered it virtually impossible that I would have cancer," she said. "I work out, I eat right, I take care of myself and I have very little family history; in fact, all of my grandparents are still alive."

Roback could not be in more brave company. After a 2007 breast cancer diagnosis, Roberts underwent a mastectomy, surgery to remove her breast, chemotherapy and radiation. Five years later, she dealt with a disease of the bone marrow. And has a smile on her face for viewers every morning since she returned to work early last year.

Robach, who is married to actor Andrew Shue, went public with her diagnosis Nov. 11. She had a bilateral mastectomy followed by reconstructive surgery Nov. 14.

She changed her hair January. And on Thursday, she had her eighth and final round of chemotherapy.

 "This is a huge milestone for me and for anyone else who has battled cancer, and I join the ranks of 2.8 million U.S. women who are breast cancer survivors."
