Good Morning America
anchor Robin Roberts announced Wednesday that she will begin undergoing chemotherapy Thursday to treat her breast cancer
, but plans to stay on air as much as possible.
"I'll work as much as I can," Roberts said on the morning show. "Part of the reason I am coming forward is in case you tune in and it looks like Kojak is sitting next to Diane [Sawyer], you'll understand why."
After a successful surgery on Aug. 3
, Roberts said her doctors determined that chemotherapy followed by radiation will be the most effective form of treatment.
"Tomorrow I will come in, and then head off for my chemotherapy," she said, expressing thanks for all the support she's received.
"Somebody said eat a lot of bacon before I have chemo," Robert added about tips from viewers on getting through her treatment. "I don't know about that one. That's a new one."
