NEW YORK — A month after undergoing a mammogram on “Good Morning America,” ABC’s Amy Robach said Monday she has breast cancer and will have a double mastectomy and reconstructive surgery this week.

The 40-year-old correspondent admitted she had been reluctant to have the public mammogram but went ahead after “GMA” anchor Robin Roberts told her that if the story saved one life, it would be worth it.

“It never occurred to me that life would be mine,” she said.

Robach joined ABC in 2012 from NBC, where she was a “Weekend Today” host. She logged considerable time with the cast of ABC’s top-rated morning show, filling in for Roberts, who has fought back from a serious blood and bone marrow disease.

Producers chose her for the mammogram story because, at 40, she’s at the age when it’s recommended that women regularly check for breast cancer. Married with two children and a full-time job, Robach said she had found plenty of reasons to put it off.
