What happened

Pope Leo XIV underwent surgery in Rome on October 13 after doctors confirmed lung adenocarcinoma, according to the Associated Press. Surgeons removed the lower lobe of his right lung at Gemelli Hospital. The Vatican said the operation was successful and without complications. Leo, 71, is the first US-born pope. [1]

The Associated Press reported that the operation lasted about 90 minutes and that the Vatican described the removal as radical, indicating the cancerous tissue was fully excised. Additional treatment such as chemotherapy was not planned at the time of the announcement, though continued medical evaluation will guide his recovery. [2]

Reuters said Leo is expected to remain in the hospital for roughly a week and that public engagements are canceled through October 20. The operation is the first major health issue disclosed during his 17-month papacy. The nodule was found during a routine examination and described as small and localized. [3]

Context and implications

Vatican News had carried Leo’s own earlier announcement that he would undergo surgery for a localized lung nodule. That notice established the planned admission date but did not yet confirm cancer. The diagnosis was reported after the procedure, making the post-operative announcement the significant new development on Tuesday. [2]

Leo’s planned November trip to Uruguay, Argentina and Peru remained scheduled before surgery, though the Vatican had not issued a final post-operative decision. Recovery time and medical advice will determine whether travel proceeds. Routine Vatican administration continues, but matters requiring the pope personally may wait until he resumes work. [3]

The discovery queue labeled the topic “Pope Francis,” but its linked stories and independent reporting concern Pope Leo XIV. Francis died in April 2025. Correcting that mismatch is essential because attributing Leo’s diagnosis and surgery to his predecessor would create a false report about both men. [1]
