Pope Leo XIV diagnosed with Lung Cancer after successful surgery

Pope Leo XIV has been diagnosed with lung cancer after surgeons removed the lower lobe of his right lung during a successful operation in Rome, the Vatican has announced.

The 71-year-old pontiff underwent surgery at Agostino Gemelli University Hospital on Tuesday, October 13, after doctors discovered a small growth during routine medical examinations.

The procedure lasted about 90 minutes and was completed without complications, according to the Vatican.

Medical tests conducted during the operation confirmed that the growth was a pulmonary adenocarcinoma, a common form of lung cancer.

The lower lobe of the Pope’s right lung was removed using a video-assisted surgical technique intended to eliminate the cancerous tissue.

Following the operation, Pope Leo regained consciousness normally and returned to his hospital room after a brief period of observation.

Vatican News reported on Wednesday that he had spent a calm first night in hospital, with further updates expected from the Holy See Press Office.

The Vatican has not disclosed the cancer’s precise stage or confirmed whether it has spread to lymph nodes or other parts of the body.

Those details remain important in determining the pontiff’s prognosis and whether further treatment will be required.

Pope Leo announced his planned surgery on Sunday during his traditional Angelus address in St Peter’s Square, telling worshippers that doctors had discovered a small, localised lung nodule at an early stage and recommended its removal.

The announcement prompted concern among Catholics and other well-wishers around the world. On Tuesday, the Pope waved to people gathered outside the hospital as he arrived for treatment.

He also greeted hospital staff before entering the building, according to reports by Reuters and Euronews.

The Holy See has said the Pope is expected to remain in hospital for approximately one week while recovering.

His public engagements have been cancelled through October 20 to allow him time to recuperate.

The diagnosis marks a significant health challenge for Leo, who was elected leader of the Catholic Church on May 8, 2025, following the death of Pope Francis.

Born Robert Francis Prevost in Chicago in 1955, he spent many years serving as a priest and bishop in Peru before becoming pontiff.

He is scheduled to undertake an 11-day visit to Uruguay, Argentina and Peru from November 6 to 17, although it remains unclear whether his recovery will affect those plans.
