Pope Leo had lobe of lung removed as doctors found cancer, Vatican says

Pope Leo XIV was diagnosed with lung cancer after surgeons removed the lower lobe of his right lung during an operation on Tuesday, 13 October 2026, according to a medical bulletin released by the Vatican. The procedure confirmed that the 71-year-old pontiff is suffering from lung adenocarcinoma, a common form of the disease, after doctors initially identified a small, localized nodule during routine health checks.

The surgery, conducted using a minimally invasive video-assisted technique, took place at the Agostino Gemelli University Policlinic in Rome, as reported by Kq2. According to a joint statement from lead surgeon Professor Stefano Margaritora and Dr. Luigi Carbone, the pope spent approximately three hours in the operating room, with the surgical procedure itself lasting around 90 minutes. The Vatican stated that the operation concluded without complications and that the pontiff woke up normally before returning to his hospital room on the 10th floor.

Pope Leo XIV diagnosed with lung cancer, Vatican says

The health crisis began to unfold publicly on Sunday, 11 October 2026, when Leo announced the discovery of the nodule to crowds gathered in St. Peter’s Square during his noon Angelus prayer. Sbs noted that the pontiff displayed a rare level of transparency regarding the first publicly disclosed major health issue of his 17-month papacy, noting that the growth had been detected at an early stage. Vatican Secretary of State Cardinal Pietro Parolin told Italian media that he was struck by the serenity with which the pope shared the news, admitting that the sudden need for surgery came as a surprise.

Before the operation, as medical staff and hospital leadership gathered in the chapel to recite the Rosary, the Vicar of Rome, Cardinal Baldassare Reina, led prayers for the pontiff's recovery, according to reporting from CBS News. Upon his arrival at the hospital earlier in the day, Leo walked through the main entrance, greeted staff, and waved to well-wishers.

Oncologists not involved in the papal care have expressed optimism about the long-term outlook. Prior to the diagnosis confirmation, specialists noted that early-stage lung nodules carry highly favorable survival rates when treated promptly. Ntd highlighted that the radical removal of the lobe was intended to excise all suspect tissue. While the medical bulletin made no immediate mention of adjuvant therapies such as chemotherapy, the Vatican press office noted that the surgical resection aimed to completely clear the affected area.

The Chicago-born pontiff, formerly known as Robert Prevost and elected in May 2025 as detailed by NTD, has otherwise enjoyed a reputation for robust health, maintaining an active lifestyle that includes swimming and playing tennis. His medical history includes a single prior hospitalization in 1985 when he contracted typhoid fever while serving as a missionary in Peru, an experience he later described as formative to his spiritual path, according to WLWT.

Logistical questions remain regarding the pope's upcoming international travel schedule. Leo is currently scheduled to undertake an ambitious trip to South America from 6 to 17 November 2026, visiting Uruguay, Argentina, and Peru. While oncologists typically advise patients to avoid flying for three weeks following thoracic surgery—an interval that would narrowly accommodate the departure date—Vatican officials have not yet confirmed whether the itinerary will be altered. Tokyo Cardinal Kikuchi Tsutomu remarked before the surgery that the operation was expedited precisely to preserve future overseas travel plans.

In the interim, day-to-day administrative matters continue under established Vatican protocols. As noted by NBC10 Philadelphia, scheduled events such as the presentation of the inaugural Pope Leo XIV Sustainability Medal proceeded at the Vatican in the pope's absence, led by Cardinal Michael Czerny. Church governance rules dictate that the pontiff retains full authority while hospitalized, and any official documents requiring his personal signature are temporarily postponed until his recovery is complete.

What to Watch Next

• The Vatican is expected to release further medical updates regarding pathology results and whether any additional treatments will be required beyond the surgical resection.
• Public audiences remain officially canceled through 20 October 2026, serving as the initial benchmark for his recuperation at Gemelli hospital.
• A definitive announcement from the Holy See is anticipated regarding whether the pope's November tour of Uruguay, Argentina, and Peru will proceed as planned.
