Pope Leo XIV enters Gemelli hospital for surgery to remove lung nodule

Pope Leo XIV arrived at Rome's Agostino Gemelli hospital on Tuesday, 13 October 2026, for surgery later that afternoon to remove a nodule from his lung.

The 71-year-old American-born pontiff walked into the main entrance and waved to well-wishers gathered outside. The Vatican confirmed that the procedure would be performed by the hospital's thoracic surgery team under Dr. Stefano Margaritora.

Leo first disclosed the finding on Sunday during his Angelus address in St Peter's Square. He stated that doctors had discovered the nodule during recent medical checks, that it was detected at a very early stage, and that it was well localized. He said the doctors recommended intervention and that he had decided to proceed with removal.

The nodule is described as a small growth of tissue smaller than three centimeters. Removal under general anesthesia will allow pathologists to determine whether it is malignant. Oncologists note that early detection of such lesions typically carries a favorable prognosis even if cancer is present.

This is the first major publicly disclosed health issue of Leo's 17-month papacy. He was elected on 8 May 2025 following the death of Pope Francis. The Vatican has canceled all audiences through 20 October, matching the expected recovery period of about one week.

Cardinal Pietro Parolin, the secretary of state, told Italian media that Leo appeared calm about the procedure when they met on Monday. The pope is expected to remain in the hospital's dedicated papal suite during recovery.

Leo has a planned trip to Uruguay, Argentina, and Peru from 6 to 17 November. Vatican officials have not stated whether the surgery will alter that itinerary, though the short recovery window suggests it may proceed if no complications arise.

Gemelli has treated popes for decades. John Paul II and Francis both received care there, and the facility maintains a special apartment for pontiffs. The choice of this hospital continues that pattern.

Leo's public announcement of the nodule and the scheduled surgery reflects a higher degree of medical transparency than some of his predecessors showed. He provided specific details about the stage of detection and the localized nature of the lesion.

The procedure itself is standard for a circumscribed pulmonary nodule. Surgeons remove the growth and surrounding margin, then send the tissue for analysis. Results will determine any need for further treatment. The Vatican has not released additional imaging or laboratory details beyond the early-stage description.

Crowds outside the hospital included ordinary Romans and visitors who waited to see the pope enter. His decision to walk in and greet them continued the pattern of direct public engagement he has shown since his election.

Medical teams will monitor him overnight after the afternoon operation. Further updates from the Vatican are expected once the surgery concludes and initial recovery begins. The one-week hospitalization estimate assumes an uncomplicated course.
