A senior Vatican official has publicly acknowledged that the newly revealed lung cancer diagnosis of Pope Leo XIV has upended expectations surrounding the pontiff’s long-term tenure, marking a notable shift for the Roman Catholic Church just months into his leadership. Archbishop Paul Gallagher, the Vatican’s foreign minister who has held the role since 2014, shared candid insights in an exclusive pre-recorded interview with the BBC, set to air this weekend on BBC Radio 4’s *The Sunday Programme*. The 71-year-old Pope underwent a scheduled procedure on Tuesday afternoon at Rome’s Gemelli Hospital to remove a lower lobe of his right lung, after doctors detected a suspicious nodule during routine screening. The surgery was confirmed by the Vatican to be fully successful with no reported complications, and a post-operative pathology examination confirmed the growth was lung adenocarcinoma.
