In the latest check-up following the surgery, Netanyahu revealed in a statement on social media that doctors discovered a malignant tumor in his prostate of less than a centimeter.The Prime Minister’s Office also released two letters from his doctors to accompany the revelation on social media. “This is an early detection of very small lesions, with no metastases, as all other tests confirmed beyond any doubt,” one letter said.He does not reveal when the last check was, but an Israeli source familiar with the matter told CNN that the cancer was diagnosed several months ago. Netanyahu began undergoing radiation therapy about two and a half months ago, according to the source, and had recently completed the treatment.Netanyahu says he made the decision to undergo targeted radiation therapy and “the spot disappeared completely.”“Thank God, I am healthy,” Netanyahu said on social media. “I had a minor medical issue with my prostate that was completely treated.”
