Pope Leo XIV has undergone a successful 90-minute operation to remove a cancerous tumour from his right lung, with the Vatican confirming that he woke up normally after the procedure on Tuesday.

The 71-year-old pontiff underwent surgery at Rome’s Gemelli Hospital, where doctors removed the lower lobe of his right lung. The procedure confirmed a diagnosis of pulmonary adenocarcinoma, according to a Vatican statement. Further tests are being conducted to determine whether the cancer has spread.

The Vatican said the surgery was completed without complications, adding that the Pope had requested dinner afterwards. His recovery is expected to take about a week, while his audiences have been cancelled until October 20.

Medical experts say the prognosis for lung adenocarcinoma can be favourable when detected early and confined to the lung, although further treatment will depend on the cancer’s stage and whether it has spread.

The surgery marks Leo’s first hospitalisation since he became head of the Catholic Church on May 8, 2025. His condition has also raised questions about whether he will proceed with a planned visit to Latin America next month.
