By Meghan Keneally PUBLISHED: 11:42 EST, 4 December 2013 | UPDATED: 16:41 EST, 4 December 2013 Good Morning America correspondent Amy Robach's return to ABC has been pushed back from the previously announced date as the network was side-lined by the sudden announcement that their weather anchor would be leaving the show just days later. Robach has been off the air since discovering via a televised mammogram that she had breast cancer that spread to her lymph nodes. She had a double mastectomy and 13 lymph nodes removed, and sent a grateful email out to colleagues on November 22 announcing that she would be back on the small screen on December 2.
