Pope Leo XIV is set to undergo surgery at Rome’s Gemelli hospital this week to remove a small lung nodule discovered during recent medical tests. The nodule, measuring less than three centimeters, was detected early and is expected to require about one week of recovery time post-operation. The Vatican emphasizes that Pope Leo remains otherwise healthy and fit, both positive indicators for his prognosis. Despite the surgery, he has not yet confirmed any changes to his upcoming travel plans or responsibilities.

Pope Leo XIV is scheduled to have an operation this week to remove “a localized nodule” in his lung that was “detected at a very early stage.”

that → schedule → stage
The Vatican said he will be admitted to Rome’s Gemelli hospital on Tuesday, and predicted a weeklong recovery.
asserted
he → say → recovery
Here is what is known:
A nodule can be benign or malignant
A lung nodule is a small abnormal area measuring less than three centimeters (about 1.2 inches) across.
asserted
nodule → know → centimeters
It is sometimes detected on a CT scan performed to investigate another problem, such as trauma or a lung infection, according to the American Cancer Society.
uncertain
It → detect → Society
Experts say the nodule could be benign or malignant and that prompt evaluation is important.
uncertain
evaluation → say → ?
If the nodule is cancerous and removed at an early stage, the prognosis is “excellent,” and surgery alone may be sufficient treatment, said Dr. Stephen Liu, a lung cancer expert at Georgetown’s Lombardi Comprehensive Cancer Center.
uncertain
Liu → remove → Center
Leo, 71, is considered otherwise healthy and physically fit, both positive factors for his recovery.
asserted
Leo → consider → recovery
He said the nodule was discovered during “recent medical tests,” and the Vatican said Monday that no particular health issue prompted the check-up, describing it as “routine.”
asserted
issue → say → it
Surgery followed by a week of recovery
The Vatican said Leo will be admitted to the hospital on Tuesday in the late morning and undergo surgery in the first days of this week.
asserted
Leo → follow → week
Oncologists who aren’t treating him said patients can often be discharged after just a few days, to recover further at home.
asserted
patients → treat → home
The exact date of surgery wasn’t released, but Leo had a full slate of audiences and appointments Monday morning and afternoon.

The pope will be treated at Rome’s Gemelli hospital, formally known as the Agostino Gemelli Polyclinic, a non-profit Catholic teaching hospital that is part of the Catholic Sacred Heart University.
asserted
that → get → University
The facility has a special apartment set up for pontiffs on the 10th floor that includes a private chapel.
asserted
that → have → chapel
Leo’s immediate predecessor, Pope Francis, was treated there before his May 2025 death during a long illness prompted by a respiratory crisis.
uncertain
predecessor → treat → crisis
St. John Paul II spent so much time at Gemelli that he called it “Vatican III,” after the Vatican itself and the papal summer residence at Castel Gandolfo.
asserted
he → spend → Gandolfo
Upcoming activities and trip in question
Leo has several activities scheduled this week.
asserted
Leo → have → activities
In addition to his regular meetings, he was due to celebrate a public Mass on Wednesday to close a weeklong conference on family ministry.
asserted
he → celebrate → ministry
It wasn’t known if someone else would celebrate the Mass.
Leo also has a major trip planned Nov. 6-17 to Uruguay, Argentina and Peru.
asserted
Leo → know → Uruguay
It is unclear whether the surgery and recovery will affect the ambitious itinerary, which includes a dozen flights, two helicopter rides and significant altitude changes in Peru.
uncertain
which → affect → Peru
Leo said earlier in his remarks Sunday that he still planned to make the trip.
asserted
he → say → trip
Pope remains in charge, even when unconscious
The Vatican has no specific rules governing who takes over if a pope becomes totally incapacitated.
asserted
pope → remain → rules
Even while unconscious during surgery, Leo remains pope and retains his authority.
asserted
Leo → remain → authority
Pope Francis remained in charge throughout his lengthy hospitalizations, as did St. John Paul II before him.
asserted
II → remain → him
Both made appointments and issued laws and statements from the hospital.
asserted
Both → make → hospital
A team of officials already handles day-to-day Vatican operations.
asserted
team → handle → operations
Medical advances and popes’ longer lifespans, however, have highlighted this gap in church law and prompted calls for the Vatican to prepare for a pope becoming too ill or incapacitated to govern.
asserted
pope → highlight → calls
Two days before revealing his planned surgery, Leo confirmed one significant appointment.
asserted
Leo → reveal → appointment
On Friday, he approved Filipino Cardinal Luis Antonio Tagle as the new dean of the College of Cardinals.

Tagle, 69, replaces Cardinal Giovanni Battista Re, 92, whose term Francis extended in the weeks before his death.

He presides over the previous pope’s funeral and helps lead the cardinals’ closed-door meetings before the conclave to discuss the church’s future needs.

If he is under 80 when the conclave begins, he also presides over the secret election of a new pope in the Sistine Chapel.

The Vatican released a letter Leo wrote to Re on Sunday — the day of his announcement — thanking him for his lifelong service to the church.
asserted
Leo → release → church
He noted in particular the role that Re played in the recent papal transition, when he celebrated Francis’ funeral.
