Publicist Nancy Seltzer said Monday that Domingo will undergo the surgery at a New York hospital. She would only describe the procedure as "medically recommended preventive surgery."
Seltzer says Domingo expects to resume his performance schedule after a recuperation period of about six weeks. He was on a world tour when he was stricken.
Domingo, 69, is general director of both the Los Angeles Opera and the Washington National Opera, as well as one of the world's greatest opera singers.
