Israeli Prime Minister Benjamin Netanyahu says that he has undergone treatment for prostate cancer. It was his first public acknowledgment of the diagnosis. He said that roughly a year and a half ago he had prostate surgery. Then two and a half months ago, his doctors discovered and treated a small tumor at Jerusalem’s Hadassah Hospital with radiation therapy. That was not announced at the time. The 76-year-old Israeli leader said Friday that he requested a delay to the announcement “so that it would not be released at the height of the war” against Iran.
