"Jon Lester received great news," Boston manager Terry Francona said at baseball's winter meeting in Lake Buena Vista, Florida. "He is going to have one more treatment and then he's done.
"So from where I sit, the meetings are already a success."
Lester, 22, had undergone tests in late August to determine the cause of back pain after being placed on the disabled list.

The Red Sox said on September 1st that he had been diagnosed with a form of non-Hodgkin's lymphoma, a blood cancer.
Francona declined to comment on a Boston Globe report on Tuesday that said Lester's cancer was in remission. But he said Lester was "energetic and positive".
A native of Tacoma, Washington, Lester was the club's first pick in the 2002 draft and has been considered one of their top prospects for the past several years.
He started the 2006 season at Triple-A Pawtucket before being called up. He had a 7-2 record with a 4.76 earned run average since his Major League debut on June 10th.
