Pope Leo XIV is recovering at Rome’s Gemelli hospital after surgery to remove the lower lobe of his right lung, following a diagnosis of lung adenocarcinoma, the Vatican said. The operation was successful, according to the Vatican. The diagnosis came during a preoperative examination after doctors found a small, localized nodule. The cancer’s stage has not been determined, and it is not yet known whether it has spread beyond the lung. Before the procedure, oncologists said the outlook could be “excellent” if the nodule proved cancerous because it had been detected at an early stage and would be removed. That assessment preceded the operation and is not a confirmed prognosis for the pope. Leo said Sunday that he would undergo surgery to remove the nodule. The Vatican canceled his public audiences through Oct. 20 as he recuperates. The pope, a Villanova University graduate, had been expected to present the university’s inaugural Pope Leo XIV Sustainability Medal at the Vatican before his surgery. The ceremony proceeded without him, and Cardinal Michael Czerny, a Czech-born Canadian Jesuit who leads the Vatican’s Dicastery for Promoting Integral Human Development, accepted the award.
