Pope Leo XIV Begins 12-Day Latin America Homecoming Tour Weeks After Lung Cancer Surgery as Millions Prepare to Welcome Him

Introduction

Pope Leo XIV left Rome on Friday morning for the longest and most demanding journey of his pontificate, a 12-day tour of Uruguay, Argentina and Peru that will carry him some 31,000 kilometres across three countries, through 10 cities and around 50 events, just three weeks after surgeons removed a cancerous tumour from his lung. The 71-year-old pontiff, the first pope born in the United States, departed from Fiumicino airport at 7:05 a.m. Rome time aboard a chartered ITA Airways plane, bound for Montevideo, where he was due to arrive at 4:30 p.m. local time after a flight of 13 hours and 30 minutes. The Vatican has said the pope has fully healed from his operation and that no special medical precautions are being taken for the trip, a statement that has done little to quiet the questions that will follow him across the continent: how a man who had a third of his right lung removed on October 13 can keep a schedule that includes 14 flights, two helicopter rides, 36 speeches and a visit to a city more than 11,000 feet above sea level. Yet for Leo, born Robert Prevost in Chicago and a missionary and bishop in Peru for around two decades, this is no ordinary state visit. It is, in the words of his own spokesman, a homecoming to places where he spent a long time and to which he feels closely connected, and it is the trip that will define the early character of his papacy, for better or worse, in the weeks after his surgery. This is the story of Pope Leo XIV’s Latin America tour in November 2026, his homecoming to Peru, and the health questions that travel with him.

1. What happened on Friday

1.1 The departure from Rome

Pope Leo XIV boarded his plane at Rome’s Fiumicino airport early on Friday morning, November 6, 2026, waving as he climbed the steps, according to reports from the departure. The flight, a chartered ITA Airways aircraft, took off at 7:05 a.m. Rome time, beginning a journey of more than 6,900 miles across the Atlantic, over France, Algeria, Mauritania, Senegal and Brazil, before its scheduled arrival in Montevideo, the capital of Uruguay, at 4:30 p.m. local time. The departure marked the start of the longest international journey of his pontificate and his first visit to Latin America since his election as pope. Vatican officials confirmed that the pope had personally confirmed the trip with no changes to its schedule, despite the surgery that had taken place less than a month earlier. The image of the pontiff leaving Gemelli Hospital in Rome on October 17, walking ahead of his lead surgeon, Dr. Stefano Margaritora, had already become one of the defining pictures of his young papacy; Friday’s departure added a second one, of a recovering pope choosing to travel rather than to rest.

1.2 The scale of the journey

The numbers attached to this trip are striking even by the standards of papal travel. Over 12 days, from November 6 to 17, Pope Leo is scheduled to take 14 flights, including two in a helicopter, give 36 speeches and take part in around 50 events. He will travel about 31,000 kilometres, or roughly 19,000 miles, across 10 cities, celebrate nine public Masses, visit seven cathedrals and preside over two stadium prayer vigils before returning to Rome on the morning of November 17. The itinerary gives him three days in Uruguay, three days in Argentina and six days in Peru, the longest leg of the journey. Vatican officials have described it as one of the most intense papal trips of recent years, and some reports have called it one of the most demanding overseas tours taken by a Catholic leader in decades. For a 71-year-old who underwent major lung surgery 24 days before departure, the schedule is not merely ambitious; it is a deliberate statement that the pope intends to lead from the front, and it is the detail that will dominate coverage of every stop he makes.

2. Why this trip matters so much

2.1 A homecoming to Peru

No leg of the trip is more anticipated than the final stop in Peru, where Leo’s arrival in Lima on Wednesday will be, in the words of one report, a moment full of symbolism and emotion. The pope first arrived in Peru as an Augustinian missionary priest in 1985, and he spent around two decades there as a missionary and then as a bishop, learning, as one account put it, to be the pastor he is today. He served as bishop of Chiclayo, his beloved former diocese, from 2015 to 2023, when his predecessor, Pope Francis, summoned him to Rome. He holds Peruvian citizenship, and he is so attached to Peru’s people that his spokesman, Matteo Bruni, described the tour as a homecoming to places where he spent a long time and to which he feels closely connected. In Peru he will visit Lima, the capital and largest city; Chiclayo, where he will spend two days; Cusco, the former Inca capital in the Andes; and Pucallpa, a city on the Ucayali River in the Amazon rainforest that has long been a centre of Catholic missionary outreach. For Peruvians, the visit is the return of one of their own, a man who lived among them, spoke their language and led their diocese, now returning as the head of the Catholic Church.

2.2 The first US-born pope returns to his second home

Pope Leo XIV is the first pope born in the United States, a Chicago native who became a Peruvian citizen and spent the formative decades of his priesthood in South America. That biography gives this trip a weight no ordinary papal visit carries. He is not a European pontiff touring a distant continent; he is a man returning to the land that shaped his ministry, to the people among whom he learned to be a pastor. The trip is also his first visit to Latin America since his election, and it comes at a moment when the Church in the region faces profound questions about its future, from falling Mass attendance to the growth of evangelical churches, from poverty and inequality to the political turbulence that has swept the continent. Millions-strong crowds are expected at his events, according to reports, and the Vatican will be watching the turnout closely as a measure of the new pope’s appeal in the region that is home to more Catholics than any other. For Leo himself, the tour is a chance to show the Church, and the world, who he is: a pope formed in Peru, speaking to Peru, and through Peru to the whole of Latin America.

3. The surgery that almost stopped it

3.1 The October 13 operation

Three weeks before his departure, on October 13, 2026, Pope Leo underwent surgery at Rome’s Gemelli Hospital to remove a cancerous tumour from his lung. The operation, a lobectomy, removed the cancerous lower lobe of his right lung, about a third of the organ, after a small growth was discovered during routine checks and later confirmed as cancer. The disease was localised lung adenocarcinoma, the most common form of lung cancer, and his doctors said afterwards that he would not require any further treatment. He left Gemelli Hospital on October 17, walking ahead of his lead surgeon, Dr. Stefano Margaritora, in a scene that was widely photographed. The surgery led some in the Vatican to believe the Latin America trip would be postponed or its intense schedule adjusted, according to one report, and the question of whether a 71-year-old recovering from a lobectomy should undertake one of the most demanding papal journeys in decades was openly discussed in Rome in the days that followed. In the end, the pope confirmed the trip with no changes, and his doctors confirmed the following week that he did not require further oncological treatment after surgery.

3.2 Doctors clear him to fly

The Vatican has been emphatic that the pope is fit to travel. His surgeon, Dr. Stefano Margaritora, said after the operation that there were no clinical reasons why the visit should not take place, and Vatican spokesman Matteo Bruni told journalists on November 3 that the pope is clinically fit to undertake this trip. Bruni said the pope had completely healed from his operation and that no special precautions were being taken for the tour, beyond the standard medical care that always accompanies a pope on his travels. Maria Montserrat Alvarado, the Vatican’s new communications chief, told journalists that the pope’s doctors are very confident and that he will have plenty of medical care on board should something happen, adding that they do not see that in his prognosis. Medical experts who spoke to reporters said the decision by Leo’s doctors to clear him to fly should indicate that the risk of complications from his surgery was low, that his operated lung had fully expanded and that any surgical wounds were healing without signs of infection. One pulmonologist, Dr. Matthew Triplette of the Fred Hutchinson Cancer Center in Seattle, told one outlet that the risk of a medical emergency during the trip is low, but that it could include either a collapsed lung or blood clots. The Vatican’s message, repeated across the week, has been consistent: we are speaking of a 71-year-old person in good health, and of something that you heal from, because it is surgery.

4. Uruguay first: the most secular stop

4.1 Montevideo and President Orsi

The pope’s first stop is Uruguay, the least Catholic and most secular country in all of Latin America, where he will stay until Sunday, visiting three cities. He is due to arrive in Montevideo at 4:30 p.m. local time on Friday, and his programme includes a ride along the city’s waterfront in a popemobile before a meeting with the left-wing President Yamandu Orsi. The choice of Uruguay as the opening leg is itself a statement: this is not a tour of the continent’s Catholic heartlands alone, but a visit to a country where the Church’s presence is smaller and its challenges different. Christmas in Uruguay is officially Family Day and Holy Week is officially Tourism Week, a measure of how far the country’s public life has drifted from its Catholic roots, and the pope’s visit will test whether his message can reach beyond the faithful to a society that has largely set religion aside. The Vatican will be watching the crowds in Montevideo as closely as those in Lima, because a warm welcome in the continent’s most secular country would say something important about the new pope’s reach.

4.2 A church in a secular country

Uruguay’s secular character shapes everything about the opening days of the tour. The country’s Catholics are a minority in practice, even if many Uruguayans still identify with the faith, and the Church there has long had to make its case in a public square that does not take its authority for granted. For Leo, who spent his priesthood in Peru, where Catholicism is woven into daily life, Uruguay presents a different kind of pastoral challenge: how to speak to a society that respects the pope as a world figure but may not share his faith. His meetings with political leaders, prisoners, the poor and old friends, as one report described his programme, will be watched for the tone he strikes, whether he leans into the social questions that animate Uruguay’s left-wing government or keeps his message firmly on the spiritual ground. The three days in Uruguay are short, but they set the tone for everything that follows, and a misstep there would follow him to Buenos Aires and Lima.

5. Argentina: the land of his predecessor

5.1 Three days in Francis’s homeland

After Uruguay, the pope will spend three days in Argentina, the home of his predecessor, Pope Francis, to whom Leo owes his pontificate. Francis summoned him from Chiclayo to Rome in 2023, and it was Francis’s decision that put the former missionary bishop on the path to the papacy. Visiting Argentina is therefore both a courtesy and a pilgrimage, a chance for Leo to honour the man who made his rise possible and to speak to the country that produced the first Latin American pope. The Argentine leg of the tour will inevitably be read through the lens of Francis’s legacy, and Leo will be measured, fairly or not, against the towering figure of his predecessor. How he handles that comparison, whether he embraces it or gently steps out from behind it, will be one of the most closely watched aspects of the trip. Argentina’s Catholics, who lived through Francis’s pontificate as a source of national pride, will be looking for a sign that the new pope values their country and their Church as his predecessor did.

5.2 What the visit means for Argentine Catholics

For Argentine Catholics, the visit carries a particular emotional charge. Francis never returned to his homeland as pope, a fact that was a source of quiet disappointment for many Argentines, and Leo’s arrival is, in a sense, the visit Francis never made. The pope’s programme in Argentina will include meetings with political leaders and the poor, and his words there will be parsed for any signal about how he sees the Church’s role in a country wrestling with economic hardship and political division. The three days are the shortest national leg of the tour, but they may be among the most symbolically loaded, because Argentina is where the story of the last papacy began and where the story of this one will, in part, be judged. If Leo can speak to Argentines as a man who knew and loved their pope, rather than as a distant successor, the visit will have done its work.

6. Peru: the emotional heart of the tour

6.1 Chiclayo, his former diocese

The tour ends in Peru, where Leo arrives on Wednesday for the longest leg of the journey, six days that will take him to Lima, Chiclayo, Cusco and Pucallpa. The two-day stay in Chiclayo, the diocese he headed from 2015 to 2023, is the emotional centre of the whole trip. This is the city where he was a bishop, where he celebrated Mass, confirmed children, buried the dead and led a community through the pandemic and its aftermath. His return there as pope will be, for the people of Chiclayo, the homecoming of a man they knew as their pastor, and the crowds expected there are likely to be among the largest of the tour. The Vatican has said the pope will celebrate nine public Masses and visit seven cathedrals across the trip, and the Masses in Peru, above all in Chiclayo, will be the moments when the tour’s emotional power is most visible. For Leo, Chiclayo is where his priesthood became what it is, and his return there is the reason this trip has been described as a homecoming rather than a state visit.

6.2 Cusco at 11,200 feet

The most testing day of the tour, medically at least, will be the visit to Cusco, Peru, the former Inca capital in the Andes, which sits more than 11,000 feet above sea level, at an altitude of 3,400 metres. At that height there is about 35 percent less oxygen per breath, a fact that has drawn attention given the pope’s recent lung surgery. The Vatican has said no special or additional provisions are planned for Leo, including when he travels to Cusco, and his spokesman has insisted that no additional medical measures are necessary. A military helicopter flight on November 14 will take him to the Andes mountain town of Santa Cruz de Succhabamba, Peru, adding another high-altitude stop to the itinerary. Doctors who have spoken publicly about the trip have said the risk of a medical emergency is low, but the Cusco visit will nonetheless be the moment when the Vatican’s reassurances are put to the test in the most visible way. If the pope climbs to 11,200 feet three weeks after losing a third of a lung and carries on with his schedule, it will be remembered as the defining image of the tour; if he struggles, the questions that have followed him since October 13 will return with new force.

7. The health questions that will follow him

7.1 The altitude and the schedule

The health questions that surround this trip are not abstract. A 12-day schedule with 14 flights, two helicopter rides, 36 speeches and around 50 events would be gruelling for a healthy 71-year-old; for a man 24 days out from a lobectomy, it is, by any measure, extraordinary. The Cusco altitude is the most obvious risk, but the sheer pace of the tour is the deeper one: a new destination nearly every day, long flights, public Masses, meetings with political leaders, prisoners and the poor, and the physical demands of greeting crowds that are expected to number in the millions. The Vatican has said a medical team will be available to him and that standard care will be provided, but it has stressed that no special measures are being taken. That confidence is itself part of the message: the pope’s doctors are very confident, in the words of the Vatican’s communications chief, and the pope himself has chosen to confirm the trip with no changes. Whether that confidence is vindicated will be judged day by day, in the pope’s voice, his energy and his ability to keep the pace he has set for himself.

7.2 What the Vatican is watching

The Vatican will be watching more than the pope’s health. It will be watching the crowds, the tone of his speeches and the reception he receives in three very different countries: secular Uruguay, Francis’s Argentina and his own beloved Peru. It will be watching whether the tour strengthens his authority in Latin America, the region that is home to more Catholics than any other, and whether it establishes him as a pope in his own right rather than as the successor of a beloved predecessor. And it will be watching the medical story, because every cough, every pause and every cancelled event will be reported and analysed as a sign of how his recovery is progressing. The trip is, in that sense, a gamble: a successful tour will settle the questions about his health and establish his leadership; a difficult one will revive them. The Vatican’s decision to proceed with no changes to the schedule suggests it believes the gamble is worth taking, and that the pope himself believes it too.

8. What remains unconfirmed and what to watch next

8.1 The crowds and the message

Much about this tour remains unconfirmed as it begins. The size of the crowds that will greet the pope in each country is not yet known, and reports of millions-strong crowds are expectations rather than confirmed figures. The content of his 36 speeches has not been published in full, and the message he will carry to Uruguay, Argentina and Peru, beyond the broad themes of his pontificate, will only become clear as the trip unfolds. Whether the tour will produce any concrete announcements, on the Church’s work in the region or on the social questions that divide these countries, is also unconfirmed. What is confirmed is the itinerary, the schedule and the pope’s determination to make the journey, and the rest will be written day by day, in Montevideo, Buenos Aires, Lima, Chiclayo and Cusco.

8.2 What to watch next

The coming days will provide the answers. Watch first for the pope’s arrival in Montevideo on Friday evening and the crowds that greet him there, because Uruguay’s reception will set the tone for the tour. Watch then for his three days in Argentina, and for how he speaks about Francis and his predecessor’s legacy. Watch most closely for Peru, for the homecoming in Chiclayo and for the visit to Cusco at 11,200 feet, where the altitude will test the recovery that the Vatican has so confidently described. And watch for the pope’s health itself, in his voice and his energy, because the trip was confirmed with no changes and no special precautions, and its success depends on the recovery holding for 12 days, 14 flights and 31,000 kilometres. The answers will come one stop at a time, and they will say as much about the new pope as about the continent he is coming home to.

The coming weeks will provide the answers.
