Pope Leo XIV told pilgrims in St Peter’s Square on Sunday, October 11, that he will have surgery in the coming days to remove a nodule doctors found on his lung, according to BBC News, The Guardian and DW. The 71-year-old, made the announcement during his Sunday noon blessing, The Guardian reports; BBC News notes that he became the first US citizen to lead the Church.

The outlets carry slightly different English renderings of his Italian remarks. According to The Guardian, Leo said that during a recent medical check “doctors found a small, localised nodule in my lung. It was detected at a very early stage and is circumscribed.” He added, in The Guardian’s translation: “The doctors believe it’s best to take action, so, following their advice, I’ve decided to have surgery to remove it.” BBC News renders the first line as “The doctors found an early, well-localised nodule on my lung,” and DW, writing with Reuters and AP material, quotes him as saying, “The operation is already planned in the coming days.”

Leo thanked the crowd and entrusted himself to their prayers, according to The Guardian and BBC News. The Guardian quotes him: “Thank you for your spiritual support, and I entrust myself to your prayers.”

The Vatican then filled in the timing. Holy See Press Office spokesman Matteo Bruni told the media that “the operation is scheduled for the first days of next week,” BBC News reports, and BBC News and The Guardian both say the Vatican expects the pope to need about a week to recover. Vatican News said the operation will take place at Gemelli Hospital in Rome, according to BBC News. The Guardian notes that Francis and earlier popes received treatment there and that the hospital keeps a special apartment for pontiffs; BBC News says the hospital set up the papal suite after the failed attempt on Pope John Paul II’s life in May 1981.

Neither the pope nor the Vatican, as the outlets report it, has described the nodule as cancer or as benign. A lung nodule measures less than 3cm (about 1in), according to the American Cancer Society as cited by The Guardian and DW. DW cites the American Thoracic Society as saying that fewer than 5% of lung nodules turn out cancerous. This desk has not seen any medical report on the pope, so the nature of the lesion seems unknown for now.

Leo has no previously known health problems, according to The Guardian, which describes him as physically active, with weekly tennis games and swimming at the papal summer retreat in Castel Gandolfo. DW calls this his first major health scare since he became pope in 2025, and notes that he took office younger than his two predecessors.

The announcement carries extra weight because of recent history. Leo’s predecessor, Pope Francis, died on April 21, 2025, of a stroke after a long hospitalisation brought on by a respiratory crisis that developed into double pneumonia, The Guardian reports; it adds that Francis suffered from chronic lung disease and had part of one lung removed as a young man.

Political leaders responded quickly. Italian Prime Minister Giorgia Meloni expressed her support and that of the Italian government to Leo “as he faces this challenge in the coming days,” The Guardian reports, quoting her statement that “the serenity and calm with which he spoke about it” offered reassurance; BBC News translates her message as “personal solidarity.” Italian President Sergio Mattarella offered his “sincerest wishes for a peaceful recovery and a speedy and full return to health,” and Israeli President Isaac Herzog wished the pontiff “a full and speedy recovery,” according to BBC News.

The travel plan seems to stand for now. BBC News reports that Leo confirmed his November visit to Uruguay, Argentina and Peru will still go ahead, and that the Archbishop of Montevideo, Daniel Sturla, said preparations will continue with “greater enthusiasm.” The Guardian, which dates the trip November 6–17, says it remains unclear whether the surgery and recovery will affect the itinerary. Whether the Vatican releases results after the operation seems likely to shape how long questions about the pope’s health last.
