The 71-year-old Pope Leo XIV announced he will undergo surgery in the coming days to remove a localized nodule recently detected in his lung. The pontiff disclosed the upcoming medical procedure directly to pilgrims gathered in St. Peter’s Square in Vatican City, noting that doctors anticipate an estimated recovery period of one week.
The surgical intervention will take place at Agostino Gemelli Hospital in Rome, the traditional clinical facility where popes receive specialized treatment, marking the first major medical event and hospitalization for the American-born pontiff during his 17 months in office. Speaking during the traditional midday Angelus prayer on Sunday (11), the leader of the Catholic Church explained the circumstances surrounding the diagnosis and requested prayers from Catholics worldwide.
“Doctors found a small, localised nodule in my lung. It was detected at a very early stage and is circumscribed. The doctors believe it’s best to take action, so, following their advice, I’ve decided to have surgery to remove it,” Pope Leo XIV told the crowd.
Surgical plan and papal schedule for Pope Leo XIV
Matteo Bruni, director of the Holy See Press Office, confirmed that the surgery is scheduled for the early days of the week, with medical teams focusing on a swift post-operative rehabilitation. The pontiff indicated that clinical preparations were already finalized prior to his public address on Sunday, October 11, 2026.
“The surgery is already scheduled for the coming days. Thank you for your spiritual support, and I entrust myself to your prayers,” the pontiff said from the window of the Apostolic Palace.

The hospitalization will interrupt the normal routine of the Holy See in Rome. On Wednesday (14), the Vatican calendar includes a closing Mass for an international conference on family pastoral ministry, an official liturgical appointment that the bishop of Rome may not be able to preside over due to his recovery.
Medical guidelines and diagnosis of lung nodules
According to clinical criteria established by the American Cancer Society, a lung nodule is typically defined as a small, rounded lesion measuring less than 3 cm across on diagnostic scans. Statistics published by the American Thoracic Society show that fewer than 5% of discovered pulmonary nodules turn out to be malignant, as the vast majority stem from benign tissue growths, healed inflammation, or scars from previous infections. Routine screenings frequently identify these circumscribed spots before any outward symptoms emerge, enabling early medical assessment.
Dr. Stephen Liu, an oncologist and lung cancer specialist at the Georgetown Lombardi Comprehensive Cancer Center, outlined the standard clinical reasoning behind deciding to excise such localized pulmonary findings.
“Lung nodules are fairly common and are often benign, but benign and cancerous nodules can have a similar appearance on imaging. When there is sufficient concern, and when it is safe to do so based on the location of the nodule and the overall health of the patient, surgical removal can provide a definitive diagnosis,” Liu stated.

Health history and background of Pope Leo XIV
Elected during the papal conclave of May 2025, Pope Leo XIV made history by becoming the first pontiff born in the United States, assuming the papacy after Pope Francis died on April 21, 2025, following respiratory complications and a stroke. Throughout his 17 months leading the Catholic Church, the pontiff maintained an active routine that set him apart from his immediate predecessors, regularly playing tennis and swimming at the papal summer residence in Castel Gandolfo, without any prior public history of serious illness or hospitalization.
Pending pathology results and upcoming South American travel
The Holy See has not published the specific day or time set for the operation at Agostino Gemelli Hospital. The exact nature of the lesion, including whether the tissue is entirely benign or malignant, remains pending and will only be confirmed following surgical excision and subsequent histopathological laboratory analysis.
Vatican officials have not confirmed whether any adjustments will be made to the papal apostolic journey across Uruguay, Argentina, and Peru, which is set to begin on November 6, 2026.
