Pope Leo XIV to Undergo Surgery This Week to Remove Lung Nodule

Pope Leo XIV told pilgrims in St Peter's Square on 11 October 2026 that doctors had discovered a small nodule in his lung during recent medical examinations and that he would undergo surgery to remove it in the coming days. This is the first major health event of his 17-month pontificate.

The 71-year-old pontiff, the first American pope, said the nodule was detected at a very early stage and is circumscribed, or well localised. He stated that doctors advised intervention and that he decided to follow their recommendation. The Vatican press office later said the operation would take place early in the week at Rome's Agostino Gemelli Polyclinic Hospital and that recovery is expected to last about one week. Cardinal Luis Antonio Tagle is scheduled to lead Mass on Wednesday.

The Vatican has not said whether the nodule is malignant. Lung nodules are common and often benign. The American Thoracic Society notes that fewer than 5 percent of such nodules prove cancerous, though risk increases with age and other factors. Leo has no previously known serious health problems and maintains an active routine that includes tennis and swimming.

The surgery will be performed under general anaesthesia. Gemelli has a special apartment prepared for popes, used by predecessors including John Paul II and Francis. Francis had chronic lung disease and had part of one lung removed earlier in life. Leo's planned trip to Uruguay, Argentina and Peru from 6 to 17 November is expected to proceed after recovery.

Leo made the announcement himself during the Sunday Angelus rather than through a written statement. He asked for prayers and thanked supporters. Argentina's bishops' conference called for special prayers for a successful operation and swift recovery. Other Catholic leaders expressed support.

The disclosure is unusual in its personal delivery from the balcony. No outward signs of illness had been reported. Leo completed a demanding schedule in France in September. The nodule was found during routine checks, not in response to symptoms that became public.

Medical details remain limited. The exact date and time of the procedure have not been released beyond the confirmation of admission late on Tuesday morning, 13 October. Postoperative care will determine any adjustments to his immediate agenda. The one-week recovery estimate covers hospital stay and initial convalescence.

This marks the first time a pope has made such a personal medical announcement of this kind in recent memory. The Vatican has released no further clinical information. Officials continue to treat the matter as a contained, early-stage finding requiring surgical removal.

Leo assumed the papacy in 2025 after the death of Francis. His relative youth and activity level have been noted compared with recent predecessors. The surgery and recovery will be the first significant interruption of his public schedule. Pilgrims and the wider Church have been asked to remember him in prayer during the procedure and hospital stay.
