| Pope Leo XIV’s |
The Vatican confirmed on Monday that Pope Leo XIV will undertake his long-planned apostolic journey to Uruguay, Argentina, and Peru from November 6 to 17, just weeks after successful surgery to remove a cancerous tumour from his lung.
The 71-year-old pontiff, who has expressed “great joy and enthusiasm” for the trip, will follow the original programme visiting around 10 cities across the three nations.
This marks the longest and most ambitious foreign journey of Leo’s roughly 17-month pontificate so far. It carries particular personal weight: the first American-born pope and dual U.S.-Peruvian citizen is returning to the continent where he spent decades as a missionary, seminary formator, and bishop.
The Diagnosis, Surgery, and Recovery
On October 11, during the traditional Sunday Angelus in St. Peter’s Square, Leo XIV openly informed the faithful that doctors had discovered a “small, localized nodule” in his lung during routine examinations. He described it as well-contained and detected at an early stage, adding that specialists had recommended its removal.
The transparency was notable; papal health matters have historically often been handled with greater discretion. Surgery took place on October 13 at Rome’s Agostino Gemelli University Hospital, the facility long associated with papal care.
Thoracic surgeon Professor Stefano Margaritora led a team that performed a video-assisted lobectomy, removing the lower lobe of the right lung to achieve a radical resection. Intraoperative examination confirmed lung adenocarcinoma, the most common form of lung cancer.
The procedure itself lasted approximately 90 minutes within a roughly three-hour operating room period and proceeded without complications.
Leo recovered more rapidly than initially anticipated. He was discharged on October 17 after four days, walking out and greeting well-wishers. Margaritora later described him as an “ideal patient”—serene, cooperative with physiotherapy and diet, and rarely complaining. Follow-up tests confirmed the cancer was localized, with no need for further treatment such as chemotherapy or radiation.
The pope has been gradually resuming duties while adjusting his schedule in consultation with doctors. He cancelled a planned October 27 visit to Assisi on medical advice to support recovery, particularly avoiding a helicopter flight.
Regarding the South American itinerary, which involves a dozen flights, two helicopter rides, and significant altitude changes (notably in Cuzco, Peru), Margaritora stated there are “no clinical reasons” why it should not proceed.
Oncologists often advise against flying for about three weeks post-lobectomy; the November 6 departure falls near that window, and the Vatican’s medical team has given clearance after recent checkups. Leo’s personal physician, Dr. Luigi Carbone, echoed that recovery is progressing favorably.

A Homecoming Rooted in Decades of Service
Born Robert Francis Prevost on September 14, 1955, in Chicago to a family of French, Italian, and Spanish heritage, Leo entered the Order of Saint Augustine in 1977, was ordained a priest in 1982, and earned advanced degrees in canon law.
In 1985, at age 30, the Augustinians sent him as a missionary to Peru. He began in Chulucanas in the Piura department, serving as parochial vicar and chancellor of the territorial prelature. He later worked extensively in Trujillo as a seminary director, teacher of canon law, parish priest, and judicial vicar, spending the better part of two decades moving between Peru and the United States.
In 2014, Pope Francis appointed him apostolic administrator of the Diocese of Chiclayo; he became its bishop the following year and obtained Peruvian citizenship. He served until 2023, also holding roles in the Peruvian Episcopal Conference. Francis then called him to Rome as prefect of the Dicastery for Bishops. Elected pope on May 8, 2025, after Francis’s death, Leo became the first pontiff from the United States, the first Augustinian, and the second from the Americas.
The Peru leg of the trip is thus deeply personal. Cardinal Carlos Castillo, Archbishop of Lima, has noted that the programme will engage young people, women involved in community kitchens (ollas comunes), and indigenous communities. Leo retains close ties to Chiclayo, where locals have celebrated his election with particular pride; a large statue of him was unveiled there in late 2025.
The Itinerary: Pastoral Depth Across Three Nations
The journey begins in Uruguay (November 6–8), the first papal visit since John Paul II in 1988. Leo arrives in Montevideo for a welcome ceremony, meetings with authorities and President Yamandú Orsi, vespers with clergy, and engagements in Paysandú and Florida (site of the national Marian shrine). A prayer vigil is planned at the historic Estadio Centenario. The Uruguayan motto is “I bring you news of great joy.”
From November 8–11 he moves to Argentina—home country of his predecessor—for the first papal visit since 1987. Stops include Buenos Aires (meeting President Javier Milei, a prison visit, youth events), Córdoba, and Luján (national shrine of Our Lady of Luján). The Argentine theme is “All are welcome—go and proclaim.”
The longest portion, November 11–17, is in Peru. After arrival in Lima and meetings with President Keiko Fujimori and local Church leaders, Leo visits Chiclayo, Cuzco, and Pucallpa in the Amazon region to encounter missionaries and indigenous peoples. Peru’s motto is “Let us open our hearts.” Roughly 76 percent of Peruvians identify as Catholic, and the visit is expected to draw large crowds.
Overall, the schedule features multiple public Masses, prayer vigils, encounters with civil society, youth, the poor, and religious communities. It covers more than 19,000 miles (some reports cite around 31,000 km including internal travel).
Significance and Broader Context
This trip arrives at a moment when Leo is still defining the early contours of his pontificate. Returning to Latin America—where Catholicism remains culturally central yet faces secularization, social inequality, indigenous rights questions, and political polarization—allows him to strengthen ties with local Churches, encourage the faithful, and project a message of faith, hope, and peace. His dual identity as both American and Peruvian positions him uniquely to bridge North and South.
The handling of his health also sets a tone of openness that contrasts with past eras of greater secrecy. By announcing the nodule himself and proceeding with a demanding schedule after clearance, Leo signals both personal resilience and institutional confidence in modern medicine.
Experts note that early-stage, localized adenocarcinoma treated by lobectomy often carries a favorable prognosis, especially in a patient without reported prior smoking history or major comorbidities.
As preparations intensify in Montevideo, Buenos Aires, Lima, and Chiclayo, local Churches are mobilizing. For many Peruvians who knew him as “Father Robert” or Bishop Prevost, the visit represents more than a papal tour—it is the return of one of their own. Leo himself has said: “I am looking forward to returning to the continent where I’ve experienced so many moments of my life.”
The Vatican has stressed that the full original programme will be maintained. With medical clearance in hand and recovery on track, Pope Leo XIV is set to embark on a journey that is at once pastoral, personal, and symbolic of continuity and renewal in the Church’s engagement with the Americas.
