Pope Leo XIV Recovers After Lung Cancer Surgery, South America Tour Uncertain

Pope Leo XIV has been diagnosed with lung adenocarcinoma, a common form of lung cancer, following surgery to remove the lower lobe of his right lung at Rome’s Gemelli Hospital on October 13. The Vatican confirmed the diagnosis after an examination of lung tissue during the operation, raising questions about the 71-year-old pontiff’s recovery and upcoming international engagements.

The procedure was performed by a thoracic surgery team led by Professor Stefano Margaritora, head of thoracic surgery at Gemelli Hospital. Using a video-assisted technique, surgeons removed the entire lower lobe of the Pope’s right lung. The operation lasted approximately 90 minutes and was completed without complications. The Pope regained consciousness normally and returned to his hospital room after observation.

A Vatican medical bulletin issued on October 14 said his postoperative recovery was progressing normally. Blood tests and a chest X-ray showed results within the expected range. Leo had begun walking around his room, undergone respiratory physiotherapy and resumed eating normally. He is expected to remain hospitalised for approximately one week, with public audiences and engagements cancelled through October 20.

Lung adenocarcinoma develops in glandular cells and is the most common type of lung cancer. Although surgery can be effective when the disease is localised, the Vatican has not disclosed the cancer’s stage, whether nearby lymph nodes are involved or whether further treatment will be necessary. These details will be important in determining the Pope’s prognosis.

Born Robert Francis Prevost in Chicago, Leo XIV became the first American-born pope when elected on May 8, 2025. He spent many years serving the Church in Peru, including as a missionary and bishop of Chiclayo, making his planned return to the country particularly significant.

His scheduled November 6–17 South American tour, covering Uruguay, Argentina and Peru, remains uncertain. The 11-day journey would be among the most demanding international trips of his papacy, but its continuation will depend on his recovery and medical advice.

Meanwhile, the Holy See’s administrative functions continue during his hospitalisation. Further medical assessments are expected to guide treatment decisions, while the Vatican’s next announcements will clarify the pontiff’s recovery and future schedule.
