Cash's upcoming recording session has also been postponed while she has the operation
at New York Presbyterian Hospital to treat a rare, but benign condition.
The daughter of country music icon Johnny Cash is expected to make a full recovery and will return to the studio to complete the recording of her debut for Manhattan Records, the label said in a statement.
Cash also plans to resume her live performance schedule in the spring and complete a new book to be published by Viking in early 2009.
