NEW YORK — Tom Brokaw says his cancer is in remission.

The veteran NBC newsman announced Sunday that, after months of chemotherapy, he soon will begin a drug maintenance program.

Sharing with colleagues what he called “very encouraging news,” Brokaw’s internal memo noted that a year ago his future was “more uncertain than I cared to acknowledge.”

Last February, he revealed that six months earlier he was diagnosed with multiple myeloma, a cancer affecting blood cells in thebone marrow, and was undergoing treatment.
