Pope Leo Begins Grueling Latin America Tour Weeks After Cancer Surgery

Pope Leo XIV began a 12-day tour of Latin America on Wednesday, embarking on his longest and most demanding journey just three weeks after undergoing surgery for lung cancer.

The 71-year-old pontiff is scheduled to visit Uruguay, Argentina, and Peru, covering roughly 19,000 miles across the region.

His itinerary includes 10 cities, 36 speeches, and 14 flights, featuring a high-altitude stop in Cusco, Peru, that sits more than 11,000 feet above sea level.

The journey marks a major test of the pontiff's physical endurance following an operation last month in which surgeons removed part of his right lung after discovering a tumour during a routine scan.

Vatican officials insisted that no extraordinary medical measures were required for the trip, describing the pope as a healthy individual who required only ordinary assistance.

"His doctors are very confident and he'll have plenty of medical care on board should something happen," said Montse Alvarado, the head of Vatican Communications, according to CNN and NPR.

Medical experts noted that while the risk of a severe complication remains low, the grueling schedule and thin mountain air could pose challenges.

The first leg of the tour takes the pope to Uruguay, a predominantly secular nation receiving its first papal visit in 4 decades.

"When this visit by Pope Leo was announced, it filled all of our hearts with joy," said Father Fernando Laguna, the rector of Santa Maria Addolorata in Rome, reported by the BBC.

The tour will later move to Argentina, where the pontiff faces a potentially sensitive political landscape involving President Javier Milei.

The final leg of the journey includes a return to Peru, where Pope Leo spent nearly 2 decades serving as a missionary and bishop.

Organizers and local clergy spent days preparing reception sites, cleaning streets, and erecting stages for the pope's arrival.

Uncertainty remains over how the pontiff will manage the demanding altitude and rigorous daily events as the tour unfolds across the three nations.
