U.S. news anchor Amy Robach has discovered she is battling a double cancer issue while undergoing a bilateral mastectomy this week (end22Nov13).

The ABC News presenter went public with her health crisis earlier this month (Nov13) after revealing a mammogram she took as part of a Tv piece had detected breast cancer.

The former Today show host on Nbs has now revealed medics discovered another previously undetected malignancy during surgery.

In a post to ABC News on Friday (22Nov13), she wrote, "No Mri, no mammogram, no sonogram had found it... I will have more treatments ahead of me, but none that will take me out of work.

"My prognosis is good. As of right now, I plan to head back into the building Monday, Dec. 2, and I couldn't be more excited to get back to work."
