Scribner spokesman Brian Belfiglio (bel-FIG'-lee-oh) says the 78-year-old writer is being treated for melanoma, the deadliest form of skin cancer.
McCourt's brother Malachy (mal-uh-KEYE') says reports that his brother is gravely ill are "exaggerated" and the cancer is in remission. He says his brother is "a hearty fellow and he's survived worse than this."
McCourt's agent, Molly Friedrich, says the New York-born author was in the hospital about a month ago but is back home. She says he is "doing pretty well" and undergoing chemotherapy.
McCourt's other books include "'Tis" and "Teacher Man."
