Pope Leo XIV has been diagnosed with lung cancer after undergoing scheduled thoracic surgery at Rome’s Gemelli University Hospital, the Holy See Press Office confirmed in an official medical bulletin. The 71-year-old pontiff underwent a surgical procedure during which specialists performed a lobectomy to excise the lower lobe of his right lung. According to the medical team, an intraoperative histological examination conducted on tissue samples confirmed a diagnosis of lung adenocarcinoma, matching clinical suspicions raised during preoperative diagnostic evaluations. The Holy See reported that the operation was carried out successfully without complications, and the Pope woke normally before returning to his private room on the hospital’s tenth floor to begin his postoperative recovery.

Details of the Lobectomy and Surgical Procedure at Gemelli Hospital

The operation was led by Professor Stefano Margaritora, head of thoracic surgery at Gemelli Hospital, alongside Dr. Luigi Carbone, Professor Elisa Meacci, Dr. Maria Teresa Congedo, and Dr. Leonardo Petracca Ciavarella, supported by an anesthesiology team directed by Professor Massimo Antonelli. To ensure a radical and curative resection of the affected tissue, the surgeons removed the entire lower right pulmonary lobe utilizing an advanced video-assisted thoracic surgery (VATS) technique. Pope Leo was in the surgical suite for approximately three hours, with the procedure itself concluding in 90 minutes. Doctors noted that further histological assessments will be analyzed in the coming days to determine subsequent therapeutic paths, with no immediate decisions taken regarding chemotherapy or adjuvant treatments.

Public Engagements Paused as Recovery Protocol Begins

Following the medical intervention, the Vatican announced that all official audiences and public engagements for Pope Leo XIV have been cancelled through at least October 20 to facilitate rest and monitoring. The pontiff had travelled nine kilometres north from Vatican City to Gemelli Hospital on Tuesday afternoon, greeting officials and well-wishers prior to admission. Vatican medical directors anticipate an inpatient observation period of about a week, barring unforeseen clinical developments. While day-to-day administrative machinery of the Roman Curia continues uninterrupted under the Secretariat of State, global dioceses and Catholic communities have organized prayer vigils for the recovery of the church’s spiritual leader.

Papal Health Background and Upcoming Global Commitments

Elected to the papacy by the College of Cardinals in May 2025, Pope Leo XIV—born Robert Prevost in Chicago in 1955—is widely recognized for maintaining an energetic schedule, having served decades as a missionary and bishop in Peru prior to his elevation. An avid tennis enthusiast and non-smoker, the pontiff had not experienced major public health issues prior to the routine checkup that identified the lung nodule earlier this month. International observers are tracking his convalescence closely ahead of an ambitious 11-day apostolic journey to Latin America scheduled for November 6 to 17, which includes planned pastoral visits across Uruguay, Argentina, and Peru.
