- Lead. Pope Leo XIV left Rome’s Gemelli Hospital on Saturday, five days after surgeons removed the lower lobe of his right lung.
- Fact. Post-operative tissue analysis confirmed lung adenocarcinoma; outside experts described his prognosis as “very good,” and the Vatican kept his November Latin America tour on the calendar.
- Stake. The discharge ends an uncertain week that interrupted the pope’s public schedule and drew sustained attention to the health of a pontiff whose two-year papacy has centered on social justice and digital ethics.
The Vatican announced on October 11 that doctors had found a small, well-localized nodule in Pope Leo XIV’s right lung and that surgery was scheduled for that week. Leo told worshippers at the Sunday Angelus that he would undergo the procedure and asked for their prayers. Two days later, on Tuesday, October 13, surgeons at Gemelli Hospital removed the lower lobe of his right lung in an operation lasting roughly 90 minutes. The Holy See Press Office said the procedure was successful, and a subsequent tissue analysis confirmed the nodule was a lung adenocarcinoma, a common and often treatable form of lung cancer, according to NPR.
Recovery and discharge
Leo remained at Gemelli as doctors monitored his recovery, and his public schedule was cleared through at least October 20. On Saturday, October 18, physicians judged him well enough to return to the Vatican. Outside specialists who reviewed the Vatican’s disclosures said the early-stage, well-localized nature of the tumor gave him a favorable prognosis. Aides told reporters he was expected to appear at his apartment window Sunday to lead the Angelus, his first public act since the operation. The Vatican said his November pastoral tour of Latin America remained on the schedule, though it noted his activities would be reviewed as recovery progressed.
Context: a papacy interrupted
Leo XIV was elected in May 2025, taking the name of a pope associated with Catholic social teaching. His first full year in office has been marked by a series of pointed public interventions, including a speech in Paris warning against what he called a “machine paradise” eroding human dignity and continued advocacy on poverty and migration. The lung cancer diagnosis, disclosed immediately after surgery, is the first major health event of his pontificate and has prompted wide commentary on papal succession procedures, though the Vatican has been explicit that no such deliberations are taking place.
Lung adenocarcinoma at an early stage, when surgically removed, generally carries a high five-year survival rate. The Vatican said it would provide further updates on his recovery as they become available.
