Pope Leo XIV has stunned Catholics around the world after revealing that he will undergo surgery in the coming days following the discovery of a suspicious growth on his lung.
The 71-year-old pontiff made the unexpected announcement Sunday, October 11, during his weekly Angelus address at the Vatican, telling thousands of worshippers gathered in St. Peter’s Square that doctors had discovered a small, localized lung nodule during recent medical examinations.
Although the growth was detected at an early stage, physicians recommended removing it surgically rather than waiting, prompting the pope to schedule an operation for early this week.
The announcement immediately raised concerns about the health of the first American-born pope, who has maintained a busy international schedule since becoming head of the Roman Catholic Church in May 2025.
Speaking from the window of the Apostolic Palace, Leo addressed the situation directly, explaining that his doctors believed surgery was the appropriate next step.
“Dear friends, during some recent medical examinations, the doctors found a small, localized nodule in my lung,” he told the crowd.
“It was detected at a very early stage and is well-localized.”
The pope explained that he had accepted his medical team’s recommendation and would undergo an operation to remove the growth within days.
“The doctors believe that it is best to intervene, so, following their advice, I have decided to undergo surgery to remove it,” he said.
Leo concluded the announcement by thanking the faithful for their support and asking them to keep him in their prayers.
Despite the serious medical news, he remained composed throughout the appearance, ending his address by wishing the crowd a happy Sunday.
Shortly afterward, Vatican spokesman Matteo Bruni confirmed that the surgery would take place at Rome’s Gemelli Hospital, one of Italy’s leading medical facilities and a hospital with a long history of treating popes.
Bruni said the procedure was scheduled for the beginning of the week and that doctors anticipated approximately seven days of hospitalization during the pope’s recovery.
The Vatican has not disclosed the exact size of the nodule, whether doctors suspect cancer, or what type of surgical procedure will be performed.
A lung nodule is a small growth or spot in lung tissue that is often discovered during medical imaging. While many nodules are harmless and can result from inflammation or previous infections, others require closer examination because they may represent an early form of cancer.
The discovery of a nodule does not automatically mean a person has cancer, and Vatican officials have not announced any cancer diagnosis.
However, the decision to remove the growth reflects the medical team’s determination that surgery is the most appropriate course of action.
The health announcement comes during a particularly active period for Leo, who was elected pope in May 2025 following the death of Pope Francis.
Born Robert Francis Prevost in Chicago, Leo became the first American to lead the Catholic Church, making his election a historic moment for Catholics across the United States.
Before becoming pope, he spent much of his ministry working in Peru and later served in senior positions at the Vatican. He is also known for maintaining an active lifestyle, including a longtime interest in tennis.
Unlike his predecessor, who experienced several serious health problems during his final years, Leo has generally appeared physically active throughout his papacy.
His unexpected announcement therefore represents one of the first major publicly disclosed health concerns of his time as pope.
The choice of Gemelli Hospital is significant because the facility has treated several pontiffs, including Pope John Paul II and Pope Francis.
Francis underwent abdominal surgery there in 2023 and was hospitalized for pneumonia in early 2025, making the institution familiar to Catholics who followed his medical struggles.
Leo’s upcoming operation is not currently expected to require a prolonged hospital stay, although Vatican officials have cautioned that additional information will be provided as his treatment progresses.
The timing is also important because the pope is preparing for a major international trip in November.
He is scheduled to visit Uruguay, Argentina and Peru beginning November 6, an ambitious journey that would take him back to the South American region where he spent much of his religious career.
As of Sunday, the Vatican had not announced any changes to those travel plans.
The surgery and expected recovery period could temporarily affect his public appearances, but officials have not indicated that his broader responsibilities will be suspended.
Meanwhile, expressions of concern and support have begun arriving from religious and political leaders.
Italian Prime Minister Giorgia Meloni offered her best wishes following the announcement, while Catholic leaders encouraged worshippers to pray for the pope’s recovery.
The United States Conference of Catholic Bishops also shared a message of support, reflecting the particular significance of Leo’s papacy to American Catholics.
Sunday’s Angelus address had initially focused on spiritual teachings and international concerns, including the continuing war in Ukraine.
Before revealing his medical news, Leo appealed for the safe passage of grain shipments through the Black Sea, emphasizing the humanitarian consequences of disruptions to food supplies.
“The daily bread of millions of people cannot be held hostage by the war,” he said.
The health announcement came near the conclusion of those remarks, transforming what had otherwise been a routine Sunday appearance into an important moment in his young papacy.
For now, Vatican officials are emphasizing that the lung nodule was detected early and that doctors have already established a treatment plan.
The exact nature of the growth remains unknown, and further medical information may become available following the operation.
