Pope Leo XIV disclosed on Sunday plans to undergo an operation to remove a nodule from his lung, with the procedure scheduled to take place within days — a health development that marks the first of its kind during his 17-month tenure as pontiff. Leo, who is 71, told reporters that the nodule had been detected at an early stage and that it remained confined to a small, well-defined area. Physicians at the Vatican estimated his post-operative recovery at roughly one week.
During his Sunday noon blessing, the pope disclosed details about his condition to the assembled crowd, expressing gratitude for the bond they shared and asking for their prayers. The Vatican provided no precise timing for the procedure beyond a window falling within the opening days of the week.
Leo had one remaining public obligation on his schedule for the week — the closing Mass of a weeklong family ministry conference on Wednesday — though Vatican officials indicated his attendance was uncertain.
Speaking in Italian during his address, Leo disclosed that a bounded growth had been identified in his lung during a recent health examination, that physicians had identified the condition at an early stage, and that imaging confirmed it remained confined to a limited area. Physicians recommended the procedure, and the decision to undergo surgery was made accordingly. Leo also expressed gratitude to the faithful for their spiritual support and asked for the continuation of their prayers.
Chest and abdominal CT scans sometimes reveal a lung nodule without any prior suspicion — a small, irregularly shaped pocket of tissue measuring less than three centimetres across, or about an inch, according to the American Cancer Society's definition. Scans ordered for trauma assessment or suspected lung infection — purposes unrelated to cancer screening — can turn up nodules incidentally. A lung cancer specialist at Georgetown's Lombardi Comprehensive Cancer Center noted that while such nodules are common and frequently non-cancerous, distinguishing a benign growth from a malignant one through imaging alone is not always possible; when the nodule's position and the patient's overall condition allow it, and when concern about the finding is sufficient, surgical removal remains the most definitive way to reach a diagnosis.
The Georgetown-affiliated specialist explained that an early-stage removal, if the nodule proved cancerous, could mean surgery alone would suffice, and that detecting a growth before it has had any chance to advance or spread through the body tends, in a good number of cases, to work in the patient's favour.
No prior health conditions appear in Leo's record. His routine includes tennis and swimming sessions held at the papal summer residence in Castel Gandolfo. A papal itinerary running from November 6 through November 17 takes in Uruguay, Argentina, and Peru, and Leo indicated during his Sunday remarks that the trip remained on his agenda.
The operation is scheduled to take place at Gemelli hospital in Rome, which maintains a dedicated apartment for pontiffs and has treated previous holders of the papacy. No outward indication of the pope's admission had surfaced by that Sunday.
Papadatos-Pastos, an oncologist at The London Clinic who focuses on lung cancer, stated that the incidental discovery of a nodule on the lung does not, in itself, point to a cancer diagnosis. The physician noted that shaped margins on a nodule can lower the probability of malignancy, while underscoring that evaluation by a clinician remains the appropriate course of action and that leaving such a finding unexamined is among the most inadvisable decisions a patient can make.
Liu, a Georgetown-affiliated oncologist, described removal of such a nodule as a routine course of action for patients otherwise in sound health when the growth occupies an accessible site, noting that the procedure typically carries a brief recovery period and a low risk profile. Liu added that Leo would likely be fit for travel to Latin America provided no complications arose.
No public record connects Leo to tobacco use. Liu noted that roughly one in every five patients receiving a lung cancer diagnosis carries no prior history of tobacco use.
Dr. Massimo Di Maio, who leads the Italian Association of Medical Oncology, identified the next diagnostic step as determining whether the nodule proves benign or malignant and, should malignancy be confirmed, whether it has extended beyond its origin. Di Maio noted that when illness is caught before it has spread, the goal of medical intervention shifts toward achieving a complete recovery, and that physical fitness forms one foundation on which patients can better withstand the demands of treatment, surgery among them. Di Maio clarified that his remarks concerned the illness in general terms, as the pope was not among his patients.
Leo's predecessor, Pope Francis, died on April 21, 2025, from a stroke that followed an extended hospital stay stemming from a respiratory illness that had progressed into double pneumonia. A portion of one lung had been removed during Francis's younger years, and he lived with a persistent respiratory condition throughout his life. Updates on Francis's health reached the public through Vatican communications that varied in detail and consistency over time. A discrepancy existed between the account the Vatican offered — that Francis had gone to hospital in March 2023 for planned tests — and what the pontiff himself later described: chest pain that prompted an unscheduled visit to hospital, where doctors found bronchitis, followed by a three-day stay.
Italian Prime Minister Giorgia Meloni conveyed support for Leo, characterising that position as both her personal stance and the official posture of the Italian government. Her written statement described the composed, measured way he discussed the matter as a source of reassurance.
