Former prime minister Ehud Olmert will undergo prostate cancer surgery at a New York hospital next month.
Spokesman Amir Dan said Olmert would leave for New York on June 4. He would not name the hospital, to protect the former premier's privacy.
Last month Olmert's office said tests showed that his prostate tumor had grown and immediate treatment was required.
Dan said Israeli doctors recommended Olmert be treated by experts in the US.
Olmert,63, made his condition public in October 2007. A year later he announced his resignation over multiple corruption allegations.
