'GMA' Anchor Robin Roberts Has Surgery for Breast Cancer

"Good Morning America" anchor Robin Roberts had "very successful" surgery for breast cancer Friday and has left the hospital for home, ABC said.

Roberts, 46, revealed her diagnosis to viewers Tuesday. She said doctors believed they had caught the cancer early.

"The tests following her surgery take some time to process, so when we have more information we will update you," said ABC News spokeswoman Bridgette Maney. "Thank you for your thoughts and prayers for Robin."

Roberts' mother and sisters traveled from the Mississippi Gulf Coast and New Orleans to be with her for the surgery. The former college basketball star and sportscaster grew up in Pass Christian, Miss.

Roberts has no family history of breast cancer.

She has been an anchor at "GMA" since 2005.
