Pope Leo has lung cancer, lower lobe of right lung removed: Vatican

Pope Leo XIV's surgery confirmed that he has lung cancer, and he had the lower lobe of his right lung removed, the Vatican said Tuesday (October 13, 2026).

The tests confirmed a diagnosis of lung adenocarcinoma, the Vatican said in a medical bulletin after the surgery. It said the diagnosis had been suspected by preoperative tests and was confirmed during surgery.

The 71-year-old was in the operating room for about 3 hours, the statement said. The surgery itself lasted approximately 90 minutes. “The surgery was successful, and there were no complications,” the statement said.

Leo had walked into Rome's Gemelli Hospital through the main entrance earlier in the day and waved to dozens of well-wishers who had gathered to greet him. The Vatican said the surgery would be performed by a team led by Gemelli's chief thoracic surgeon, Dr. Stefano Margaritora.
