Country music singer and songwriter Rosanne Cash has announced she is to undergo brain surgery for a "rare but benign condition".
Cash had been promoting her album Black Cadillac
The 52-year-old Grammy-winning musician, the eldest of Johnny Cash's five children, said she expects to recover fully from the operation.
The star, who has not revealed exactly what she is suffering from, plans to resume her tour next spring.
The condition forced her to cancel four November concert dates.
She had been promoting her album, Black Cadillac, a collection inspired in part by her father's death four years ago.
Cash, who will be treated at the New York Presbyterian Hospital, topped the country singles charts 11 times, and won a Grammy in 1985.
