Norman Mailer has been hospitalized after having surgery.

His daughter-in-law, Salina Mailer, said the 84-year-old author had undergone surgery at Mount Sinai Hospital in Manhattan to remove scar tissue from around his lung. She didn't recall the date of the operation, but said he is progressing.

"He's been getting better every time I see him," she said.

Mailer has been writing for decades, starting with "The Naked and the Dead" in 1948. His latest work, "The Castle in the Forest," was published earlier this year.
