NEW YORK -- Tom Brokaw is sharing the news about his battle with cancer.

The former NBC anchor has a memoir coming out May 12, Random House announced Monday. The book is called "A Lucky Life Interrupted," and will draw upon a journal that Brokaw began keeping in 2013 after learning he had multiple myeloma.

Brokaw, 75, said in a statement issued through Random House that he hoped his book would "help others dealing with this unwelcome condition."

Brokaw's previous books include the bestselling "The Greatest Generation" and "A Long Way From Home: Growing Up in the American Heartland in the Forties and Fifties."
