Pope Leo XIV Enters Gemelli Hospital for Surgery to Remove Lung Nodule

Pope Leo XIV arrived at Rome’s Agostino Gemelli University Hospital on Tuesday morning for surgery to remove a small, localized nodule from one lung. The procedure marks the first hospitalisation of his 17-month pontificate.

The 71-year-old American-born pope announced the plan himself on Sunday during the Angelus in St Peter’s Square. He said doctors had found the nodule during recent medical examinations, that it had been detected at a very early stage, and that it was well localised. “The doctors believe it is best to take action, so, following their advice, I have decided to have surgery to remove it,” he told the crowd.

Vatican spokesman Matteo Bruni confirmed that Leo would be admitted late on Tuesday morning. The operation is scheduled for Tuesday afternoon and will be performed by the hospital’s thoracic surgery team under Professor Stefano Margaritora. The Holy See Press Office has estimated recovery at approximately one week. All papal audiences have been cancelled through 20 October.

Cardinal Pietro Parolin, the Vatican secretary of state, told reporters that Leo appeared “very calm” and “very relaxed” about the procedure when they met on Monday. Leo waved to well-wishers as he left the Vatican by car and again on arrival at the hospital before walking inside. Messages of support have arrived from bishops’ conferences and political leaders on several continents.

A lung nodule is a small growth of tissue, usually less than three centimetres in diameter. Most such nodules are benign and can result from prior infections, inflammation or scarring. A minority prove to be early-stage cancer. Because this nodule was found early and is circumscribed, specialists have noted that if malignancy is confirmed after removal, the prognosis is generally favourable and surgery alone may be sufficient treatment. The Vatican has not stated whether doctors suspect cancer.

Leo has no previously disclosed major health problems and maintains an active routine that includes tennis and swimming. He was elected in May 2025 after the death of Pope Francis and is the first pontiff born in the United States. His planned 11-day visit to Uruguay, Argentina and Peru from 6 to 17 November remains on the calendar; the Vatican has not indicated that the surgery will force cancellation, though the recovery window will require close monitoring.

Gemelli has long served as the principal hospital for popes. John Paul II spent a total of 153 days there across multiple admissions and once called it “Vatican Three.” Francis received treatment there as well. A dedicated papal suite occupies part of the tenth floor. Leo is expected to remain in that facility for the duration of his stay.

The decision to announce the finding and the surgery plan in person during a public blessing is consistent with a more open style on health matters than some earlier pontificates. Leo controlled the initial message rather than leaving it solely to the press office. Subsequent updates will come from the Holy See Press Office, with the first post-operative statement expected on Tuesday evening.

For the Catholic Church the immediate operational effect is the suspension of audiences and a temporary reduction in the pope’s public schedule. The longer-term impact depends on the pathology results and the speed of recovery. If the nodule is benign, Leo can resume a full programme within days of discharge. If further treatment is required, adjustments to the November Latin American itinerary and other engagements would follow.

The surgery itself is a standard thoracic procedure. When performed by minimally invasive techniques such as thoracoscopy, the relevant section of lung is removed after temporary collapse of the lung, and a chest drain is left in place while the lung re-expands. Risks are low for a patient in good overall condition, though any operation carries the possibility of infection or other complications related to the drain.

Leo’s age, 71, places him younger than several recent predecessors at the start of their pontificates. Francis was 76 when elected; Benedict XVI was 78. The combination of early detection, a planned elective removal, and the pope’s stated intention to keep the Latin American trip indicates that both the patient and his medical team view the situation as manageable within a short hospital stay.

Observers will watch the evening medical update and the subsequent pathology report for the first concrete indication of whether additional therapy will be needed. Until those results are known, the public record consists of the early-stage finding, the decision to operate, and the one-week recovery estimate.
