Pope Leo to undergo surgery after nodule discovered on his lung, he says

ROME and LONDON -- Pope Leo XIV is scheduled to undergo surgery in the "next few days" after doctors found a nodule on his lung, he said on Sunday.

"Recently during some check ups doctors found a circumscribed nodule in my lung," the pontiff, 71, said during an appearance at the window of the Vatican's Apostolic Palace, overlooking a sunny St. Peter’s Square. "It was found in a very initial phase and well localized. The doctors think it is opportune to intervene."

The Vatican press office said in a statement shortly afterward that the procedure was scheduled for "early" this week, adding that the "expected length of the postoperative hospital stay is about one week."

The pope is scheduled to be operated on in Rome's Gemelli Hospital, the primary medical facility commonly used by popes, including Leo's immediate predecessor, Pope Francis, who died in 2025 at the age of 88.

Leo, a Chicago native and the first American pope, who was previously Cardinal Robert Prevost, was elected the church's 267th pontiff in May 2025.

Before Leo announced on Sunday that he will be operated on, and while greeting the groups present in the square, he greeted a Peruvian Catholic group and said, "Thank you for your prayer for my apostolic visit that I will make to Peru."

Leo is officially scheduled to make a trip to Uruguay, Argentina and Peru between Nov. 6 and 17. His remark on Sunday appeared to indicate he still intended to travel to those countries.
