Mets general manager Sandy Alderson has been diagnosed with cancer, the team announced Friday.
The team's chief operating officer Jeff Wilpon said in a statement that Alderson learned of his diagnosis while undergoing a surgery three weeks ago at Memorial Sloan Kettering Cancer Center.
Wilpon said doctors are optimistic that the cancer is treatable and Alderson will make a full recovery. He's expected to undergo eight to 12 weeks of chemotherapy beginning this week. It's not clear what type of cancer he has.
Alderson is expected to continue his duties for the club through his treatments.
"We wish him and his family the very best and look forward to this getting behind him," Wilpon said.
The diagnosis comes just weeks after Alderson collapsed during a news conference announcing a contract extension for manager Terry Collins. Team officials said that Alderson felt lightheaded under media lights and had not eaten breakfast.
A former Marine who turned 68 on Nov. 22, Alderson became New York's general manager in October 2010. He was Oakland's general manager from 1983-97, Major League Baseball's executive vice president of baseball's operations from 1998-2005 and San Diego's chief executive officer from 2005-09.
