Vatican says Pope Leo XIV has lung cancer after surgery removes part of his right lung

Pope Leo XIV has been diagnosed with lung cancer. Surgeons at the Agostino Gemelli University Hospital in Rome removed the lower lobe of his right lung on the afternoon of Tuesday 13 October 2026, according to a medical bulletin that the Holy See Press Office, the Vatican’s official press service, released that evening.

The bulletin was signed by Dr Luigi Carbone, director of the Directorate of Health and Hygiene of Vatican City State, and Professor Stefano Margaritora, who led the thoracic surgery team. It said the surgeons used a video-assisted technique and removed the whole lobe so that the operation would be radical. Tissue examined during the operation confirmed a lung adenocarcinoma, which pre-operative tests had already suggested. The text was published by Vatican News, the Holy See’s news portal.

The operation

The bulletin said the Pope spent about three hours in the operating theatre and that the operation itself took about 90 minutes. The doctors said it was successful and that there were no complications. The Pope woke up normally and returned to his room on the hospital’s 10th floor after a short period of observation.

Vatican News reported that the bulletin came out at 21:53. Shortly before 20:00 the press office had issued a short statement: “The surgery was completed successfully, within the expected timeframe and as planned, and the Holy Father has returned to his room. Further information will follow.”

Vatican News said the Pope is staying in a ward next to the hospital’s papal apartment, which is being renovated. Professor Elisa Meacci and two other doctors assisted Margaritora. The anaesthesia team included Professor Massimo Antonelli.

From announcement to diagnosis

The 71-year-old pontiff first disclosed the problem on Sunday 11 October, during the Angelus prayer in St Peter’s Square. He said a small, localised nodule had been found during recent medical examinations. On Monday, Matteo Bruni, Director of the Holy See Press Office, told journalists the examinations had been routine checks. He said the hospital stay was expected to last about one week.

The Prefecture of the Papal Household cancelled all of the Pope’s audiences through Tuesday 20 October. Cardinal Luis Antonio Tagle was asked to take his place at a Mass in St Peter’s Square on Wednesday 14 October.

What is not yet known

The bulletin did not give a cancer stage or say whether more treatment would be needed. Al Jazeera, citing the Vatican, reported that doctors were not discussing chemotherapy or other therapies while the results of further tests were pending. According to the same report, the press office said the word “radical” in the bulletin meant that doctors had removed all suspect tissue. Kai Times could not check either point against a Vatican document.

It is also unclear whether his recovery will affect a trip to Uruguay, Argentina and Peru planned for 6 to 17 November. Al Jazeera reported that the Pope told reporters on Sunday he intended to make the journey. The same report said the itinerary includes a dozen flights and two helicopter rides.

The Pope’s age, the place where he gave the Angelus and the details of the November trip come only from the Al Jazeera report, which was written with the Associated Press. Kai Times could not verify them with a primary Vatican source.

The press office said further information would follow. The statements Kai Times reviewed did not give a date for the next medical bulletin.
