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

Pope Leo XIV's surgeon 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.

The American pontiff has offered a rare level of transparency about the first publicly disclosed major health problem of his 17-month papacy. He revealed the discovery of the small, localised nodule during his Sunday noon prayer and announced that he would have it removed.

The Vatican on Monday cancelled all Leo's audiences through Oct 20.

But the decision to have the operation clearly came as a surprise: While Gemelli has a specific papal apartment that past popes have used, complete with a private chapel on the 10th floor, Leo will actually be staying in a nearby room since the papal apartment is currently undergoing renovations, according to the Vatican press office.
