From the official site:

"As we begin a new year, I find myself facing a new challenge [--] the biggest of my life so far," Murcer said. "Pathology reports have revealed that the brain tumor removed was malignant. I'm not having to battle this alone, but am fortified with the most loving family, an abundance of wonderful friends and fans and the very best class of physicians.

"I'm gaining confidence that with God and my faith leading the way, we will as a team put up an incredible fight. Please continue to send up prayers. That's all I can really ask of you at this time." ...

"Bobby Murcer represents the spirit of the Yankees, and above all, he's my dear friend," Steinbrenner said. "I know Bobby very well. He has true grit, is a fighter and our entire Yankee organization offers our prayers to him and his family for a big win in this battle."

Not the news we'd hoped for. We'll be keeping him in our thoughts.
