BOSTON -

Former major league pitcher Curt Schilling said he's battling mouth cancer, and he blames his 30 years of chewing tobacco.

Schilling discussed details of his cancer on WEEI-FM in Boston on Wednesday. He announced he had cancer in February, but had not disclosed what kind.

He said it's due to chewing tobacco.

Schilling is being treated at Brigham and Women's Hospital and the Dana-Farber Cancer Institute. He received seven weeks of chemotherapy and radiation treatments and is in remission. He said he's lost 75 pounds.

Schilling is a three-time World Series champion with the Arizona Diamondbacks and Boston Red Sox. He also helped lead the Philadelphia Phillies to the World Series in 1993.
