NEW YORK – A month after undergoing a mammogram on "Good Morning America," 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 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. In her original story, she emerged from her mammogram telling Roberts and her "GMA" colleagues that it hurt much less than she thought.

A few weeks later, she returned for what she thought would be some follow-up images only to learn she had cancer. She said she will learn after Thursday's surgery what her treatment will entail going forward. "I can only hope my story will do the same and inspire every woman who hears it to get a mammogram, to take a self-exam."

Two from indi rock band shot and killed

A musician shot and killed two members of an Iranian indie rock band and a third musician early Monday, and wounded a fourth person at their Brooklyn apartment before killing himself on the roof, police and the group's manager said. Two of the dead were brothers and members of the group the Yellow Dogs, who came to the U.S. from Iran three years ago after appearing in a film about the underground music scene there, according to band manager Ali Salehezadeh. Another person killed was also a musician but wasn't in the band, and the wounded person was an artist. The shooter was a member of another band from Iran, the Free Keys. Detectives suspect there was a dispute over money

wrong name: Angela Lansbury says "it's a mistake" for NBC to call a new series "Murder, She Wrote." The network recently announced plans to reboot the show with Oscar-winner Octavia Spencer as its star. Lansbury, who starred as murder-solving mystery writer Jessica Fletcher for 12 seasons and four TV movies on CBS, says she's a fan of Spencer; she just wishes they wouldn't use the name.
