Pope Leo XIV is preparing to undergo surgery to remove a small nodule in his lung after doctors discovered the growth during a recent medical examination, the Vatican has confirmed.
The 71-year-old pontiff announced on Sunday (Oct 11) that the procedure had been scheduled for the coming days, explaining that the nodule was detected at an early stage and was well localised.
“The doctors believe it is advisable to intervene, so, following their advice, I have decided to undergo surgery to remove it,” he told pilgrims gathered in St Peter’s Square during his weekly Angelus address.
The Vatican said the operation was expected to take place early in the week, with recovery anticipated to last about seven days. Officials have not disclosed the exact date of the procedure.
Pope continues his duties ahead of surgery
Despite the upcoming operation, Pope Leo continued with his regular schedule at the Vatican on Monday, Oct 12.
He held several meetings, including engagements with church representatives and other visitors, as he prepared for the medical procedure.
The Vatican has not announced any major changes to his public schedule. A Mass planned for Wednesday in St Peter’s Square remained on the calendar as of Monday, although adjustments could be made depending on his medical needs.
The pontiff thanked supporters for their concern and prayers following his announcement.
What is a lung nodule?
A lung nodule is a small area of abnormal tissue in the lung that can be identified through medical imaging. Such growths can have several causes, including previous infections, inflammation and, in some cases, cancer.
The Vatican has not said whether Pope Leo’s nodule is benign or malignant. It would therefore be premature to draw conclusions about the nature of the growth before further medical information becomes available.
The Pope’s statement that the nodule was detected early and is well localised provides some information about its discovery, but does not by itself establish a diagnosis.
First major health concern of his papacy
Pope Leo, born Robert Francis Prevost in Chicago, became the leader of the Catholic Church in May 2025 following the death of Pope Francis.
The upcoming procedure marks a significant health development during his papacy. His predecessor experienced serious respiratory problems in the final years of his life, drawing widespread attention to the health of the Church’s leadership.
However, the Vatican has not indicated that Pope Leo is facing a similar condition.
November trip remains on the agenda
Pope Leo is scheduled to undertake an 11-day pastoral visit to Uruguay, Argentina and Peru from Nov 6 to 17.
The trip is intended to include meetings with Catholic communities and other engagements across the three South American countries.
It remains unclear whether the operation or recovery period will affect his travel plans. The Vatican has not announced any changes to the itinerary.
For now, the focus remains on the upcoming surgery and the Pope’s recovery. Further details about his condition and schedule are expected to depend on updates from the Vatican.
