Curt Schiling

BOSTON — Former major league pitcher Curt Schilling says he has been treated for mouth cancer and blames the disease on his use of chewing tobacco for about 30 years.

Schilling discussed details on WEEI-FM in Boston on Wednesday. The former Red Sox right-hander announced in February that he had cancer but hadn’t disclosed what kind. He has said he is in remission after seven weeks of radiation and chemotherapy and has lost 75 pounds.

“I’m not going to sit up here from the pedestal and preach about chewing,” he said. “It was an addictive habit. I can think about so many times in my life when it was so relaxing to just sit back and have a dip and do whatever.

“And I lost my sense of smell, my taste buds for the most part. I had gum issues, they bled, all this other stuff. None of it was enough to ever make me quit.”

Schilling revealed the type of cancer two months after Hall of Fame outfielder Tony Gwynn died at the age of 54 of oral cancer, a disease he attributed to years of chewing tobacco.

Use of chewing tobacco has been “a norm in the baseball culture,” Red Sox manager John Farrell said. “On the heels of the unfortunate passing of Tony Gwynn and now what Curt’s going through, you would think that this would be more of a current beacon for guys to take note and know that there’s a price to be paid if you’re one of the unfortunate ones that is stricken by cancer.”

Major League Baseball prohibits having smokeless tobacco in public view and imposes fines for violations. Minor leaguers cannot use it in games.

Former Red Sox left-hander Jon Lester was coming back from treatment for anaplastic large cell lymphoma in 2007, Farrell’s first year as Boston’s pitching coach. Lester, sent to Oakland at the trade deadline last month, was 4-0 that year and won the final game of Boston’s four-game sweep of the Colorado Rockies in the World Series.

“Any time a public figure who is, unfortunately, diagnosed with cancer, is able to come out and speak about it — I know how hard that can be — it brings awareness,” Lester said after Schilling’s disclosure, “and maybe sheds a little light or a little hope on somebody who’s struggling.”

Before his team faced the Red Sox on Wednesday night, Los Angeles Angels manager Mike Scioscia said the use of smokeless tobacco “is non-existent in the minor leagues during a game.”.
