Pope Leo XIV to Undergo Surgery This Week for Early-Stage Lung Nodule

Pope Leo XIV told worshippers in St Peter’s Square on Sunday that doctors had discovered a circumscribed nodule in one of his lungs and that he would undergo surgery to remove it in the coming days.

The 71-year-old American pope, elected in May 2025, said the growth was found at a very early stage and was well-localized. He decided to follow medical advice and have it removed. Vatican spokesman Matteo Bruni said the operation is scheduled for early this week at Rome’s Gemelli Hospital and that the expected recovery period is about one week. The pope is to be admitted on Tuesday morning.

This is the first major health event of Leo’s 17-month pontificate. He has no previously known serious medical conditions and maintains an active routine that includes tennis and swimming. The Vatican has not stated whether the nodule is suspected to be malignant. Lung nodules smaller than three centimetres are often benign, but early removal is frequently recommended when imaging shows features that warrant further investigation.

Leo made the announcement himself after the Angelus prayer, an unusual degree of transparency. He thanked the faithful for their support and asked for their prayers. Italian political leaders, the Italian Bishops’ Conference and Catholics in his home archdiocese of Chicago offered messages of support. He indicated he still intends to carry out a planned trip to Uruguay, Argentina and Peru from 6 to 17 November, though the schedule may be adjusted depending on recovery.

Gemelli Hospital has treated successive popes and maintains a special papal apartment. John Paul II underwent multiple procedures there; Francis was also treated at the facility. Leo’s decision to speak publicly before admission contrasts with earlier practices in which details sometimes emerged only after hospitalisation.

Thoracic surgeons note that nodules detected incidentally on scans performed for other reasons are common. When they appear circumscribed and small, surgical resection can provide a definitive diagnosis and, if malignant, can be curative at an early stage. The Vatican has not released the size or exact location of the nodule, nor the imaging modality that first identified it.

The announcement comes while the Holy See continues its ordinary administrative work. Decisions that require the pope’s personal signature or presence will pause during the hospital stay. The planned Latin American journey is the first major foreign itinerary of the pontificate and is intended to visit countries with large Catholic populations and historical ties to the previous Argentine pope.

Medical sources familiar with similar cases say most patients leave hospital within a week after uncomplicated resection of a small nodule, though full recovery of lung function can take longer. Leo’s relatively young age for a pontiff and active lifestyle are factors that usually favour quicker recovery. The Vatican has not indicated whether additional treatment beyond surgery is under consideration.

The public statement itself is part of a pattern Leo has established since his election: direct communication on matters that affect the life of the Church. By delivering the news in person from the window above St Peter’s Square, he limited speculation and set the terms of the subsequent coverage. Pilgrims present for the Angelus responded with applause after he finished speaking.

For now, the immediate sequence is admission on Tuesday, surgery in the first days of the week, and a projected one-week hospital stay. The outcome of the pathology examination will determine whether further steps are required. Until that result is known, the Vatican has limited its public comments to the fact of the early-stage finding and the planned operation.

The episode also draws attention to the medical infrastructure that supports the papacy. Gemelli’s papal suite has been used repeatedly since the 1980s. Its proximity to the Vatican and its specialised thoracic teams make it the default location for such procedures. Leo’s case will be the first time the current pope occupies that suite.
