The 71-year-old pontiff will enter Gemelli hospital on Tuesday for an operation on an early-stage lung nodule found during routine testing. The Vatican anticipates a week of inpatient recovery ahead of a planned trip to Latin America.
Pope Leo XIV will enter Rome’s Gemelli hospital late Tuesday morning to undergo surgery to remove a lung nodule, the Vatican announced. The operation marks the first major medical event of his 17-month papacy, and the Holy See predicts he will spend about a week recovering in the hospital.
Why the procedure matters
The 71-year-old American pontiff shared the news himself during his Sunday noon blessing in St. Peter’s Square, telling thousands of pilgrims that doctors had found a small, localized nodule in his lung, Al Jazeera reported. Leo told the crowd in Italian, “The doctors believe it’s best to take action, so, following their advice, I’ve decided to have surgery to remove it.”
Leo’s public disclosure reflects a distinct shift toward openness regarding papal health, according to CBS News. The Vatican has historically guarded information about papal illnesses with secrecy. While Pope Francis spoke openly about his physical frailties before his May 2025 death, details remained closely held, and he did not usually announce hospital visits in advance.
The procedure also touches on a long-standing governance question, as Catholic Church law contains no rules governing who takes over if a pope becomes completely incapacitated. Even while Leo is unconscious during surgery, he remains pope and retains full authority, PBS NewsHour reported. Francis and St. John Paul II both governed and made official decisions from hospital rooms, while an administrative team oversaw standard Vatican operations.
Background and papal duties before hospital care
The Vatican said the nodule was spotted at a very early stage during recent routine examinations. Vatican press officials denied reports in Italian media suggesting that an inflammation had prompted the checkup. A lung nodule is an abnormal spot measuring less than 3 centimeters across, and it often appears on CT scans ordered for trauma or infections.
Spokespeople haven’t said whether the nodule is malignant or benign. However, oncologists who aren’t treating the pope told NBC News that if the growth is cancerous, removing it early gives him an excellent prognosis and surgery alone might be enough. Leo is considered physically fit, with no prior history of serious illness, and he routinely swims and plays tennis.
On Monday, Leo carried out a full workday at the Vatican. He held a group audience with members of the Circolo San Pietro charity and took part in six private meetings, including one with Archbishop Timothy Broglio, who heads U.S. military chaplains. Leo also made three appointments and sent a letter to 92-year-old Cardinal Giovanni Battista Re, the outgoing dean of the College of Cardinals. Leo wrote to Re, “I do not think I am mistaken in saying that you, Your Eminence, have been and remain one of the Holy See’s best-known and most esteemed servants.” On Friday, Leo approved 69-year-old Filipino Cardinal Luis Antonio Tagle to succeed Re as the college’s new dean.
What happens next during recovery and travel
Leo will stay in a dedicated 10th-floor papal suite at Rome’s Agostino Gemelli Polyclinic, a Catholic teaching hospital that includes a private chapel. John Paul II stayed there so frequently during his lifetime that he referred to the clinic as “Vatican III.”
The Vatican hasn’t specified the exact day of the operation, stating only that it will take place in the first days of the week. Papal audiences are canceled through October 20 to allow for Leo’s recovery, though outside oncologists note that patients can often be discharged after a few days to rest at home. Before his hospital admission, Leo was scheduled to celebrate a public Mass on Wednesday to close a conference on family ministry, but the Vatican hasn’t confirmed if another officiant will replace him.
The surgery comes ahead of an international tour scheduled for Nov. 6-17, with stops across Uruguay, Argentina and Peru. That trip involves 12 flights, two helicopter rides and high-altitude travel in Peru. Leo told reporters on Sunday that he still intends to make the journey, though officials haven’t confirmed whether the travel plans will change.
