He says 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 says he's lost 75 pounds.

Schilling is a three-time World Series champion with the Arizona Diamondbacks and Boston Red Sox.

He's being sued by Rhode Island's economic development agency after his video game company received a $75 million state loan guarantee and then collapsed.
