Vatican City: Pope Leo XIV has been diagnosed with lung adenocarcinoma after undergoing planned thoracic surgery at Rome’s Agostino Gemelli University Hospital on Tuesday, the Holy See Press Office announced. Surgeons removed the lower lobe of the Pope’s right lung to ensure the radical removal of the tumour, and the Vatican said the operation was successful and free of complications.
The medical update was issued by Dr. Luigi Carbone, the Pope’s personal physician, and Professor Stefano Margaritora, the thoracic surgeon who led the operation. It said that an expedited histological examination carried out during surgery confirmed the diagnosis of lung adenocarcinoma, which had already been suspected on the basis of preoperative tests.
A Planned, Minimally Invasive Procedure
According to the statement, the Holy Father underwent surgery “as scheduled.” To achieve a radical—meaning curative—removal of the lesion, doctors removed the lower lobe of his right lung using a video-assisted surgical technique, a minimally invasive, camera-guided approach commonly used in thoracic procedures.
The Pope was in the operating theatre for approximately three hours, although the surgery itself lasted about 90 minutes. The Vatican said the procedure was successful and that there were no complications.
“After the surgery, the Pope woke up regularly and returned to his room on the 10th floor after a short period of observation,” the statement said. The update offered no immediate timetable for his discharge or resumption of public engagements.
Surgical Team and Hospital Setting
Professor Margaritora, director of thoracic surgery at Gemelli and head of the hospital’s neuroscience and chest department, led the surgical team. He was assisted by Professor Elisa Meacci, Dr. Maria Teresa Congedo, and Dr. Leonardo Petracca Ciavarella.
Gemelli Hospital, located in Rome, is the medical facility where popes have regularly received treatment. The Pope had been admitted earlier on Tuesday ahead of the operation, which the Vatican had said would be performed by the hospital’s thoracic surgery team under Margaritora’s direction.
The diagnosis of adenocarcinoma—a common form of lung cancer—was confirmed through rapid examination of tissue removed during the operation. The Vatican’s language indicated that the surgical team had proceeded on the basis of earlier clinical suspicion and used the operation both to treat and to establish definitively the nature of the lung lesion.
What the Vatican Revealed—and Did Not
The bulletin was notably specific about the procedure and the confirmed diagnosis, but it did not disclose the cancer’s stage, whether additional treatment such as chemotherapy, radiotherapy, targeted therapy, or immunotherapy would be required, or a detailed prognosis. Those questions are likely to shape renewed attention on the Pope’s health and schedule in the coming days.
Medical experts generally note that adenocarcinoma is the most common type of lung cancer and that treatment and outlook depend heavily on factors including the tumour’s size, stage, spread, and molecular characteristics. The Vatican has not provided those clinical details.
The removal of an entire lung lobe—known medically as a lobectomy—is a significant operation, but the use of video-assisted surgery can reduce surgical trauma compared with open chest surgery. The Vatican’s account that the Pope regained consciousness normally and returned to his room shortly after observation was read by observers as an early sign of a stable post-operative condition.
Global Attention on the Pontiff’s Health
News of the diagnosis prompted immediate concern and prayers from Catholics and world leaders, while Vatican watchers began assessing the potential impact on papal audiences, travel, and liturgical commitments. The Holy See has historically balanced transparency about a pope’s serious medical treatment with caution over clinical specifics.
For now, the official account is measured: the surgery was completed as planned, the tumour was removed radically, the cancer diagnosis was confirmed, and the Pope was recovering in his hospital room without reported complications. Further medical bulletins are expected to clarify his recovery and any follow-up treatment.
The development marks one of the most significant health disclosures of Pope Leo XIV’s pontificate. At 71, the Pope now faces a recovery period following major lung surgery, while the Vatican will be under pressure to provide timely updates on both his medical progress and the governance of Church affairs during his hospitalisation.
