Pope Leo XIV, 71, was diagnosed with lung cancer after surgeons removed the lower lobe of his right lung, the Vatican said. Preoperative tests had raised suspicion, and tissue testing during surgery confirmed lung adenocarcinoma, according to the Vatican.

The Vatican said the surgery was successful and had no complications. It did not give details about treatment going forward, and said doctors were not currently discussing chemotherapy or other therapies. The Vatican canceled Leo’s audiences through Oct. 20. His planned trip to South America next month had not been confirmed, MedPage Today reported.
