Future Plans and Reactions
Preparations for Leo's planned trip to South America, scheduled for November 6 to 17, are continuing. The Vatican published a list of journalists accredited to cover the visit to Uruguay, Argentina, and Peru, signaling that organizational work is "going forward," according to a Vatican spokesman.
The diagnosis has raised questions about the future of Leo's papacy, which began in May 2025. Cardinal Pietro Parolin, the Vatican secretary of state, noted that the pope might need to adjust his pontificate based on his recovery. "We can’t make any type of predictions," Parolin said, according to LaPresse and ANSA news agencies. "The question now is when he will return, under what circumstances he will return, and what the doctors say."
Chicago Cardinal Blase Cupich, a close ally of Leo, expressed shock at the diagnosis. "When I heard they took out part of the lobe of the lung and that it was malignant, that was more shocking and more concerning," Cupich told Catholic magazine America. He added that he believed Leo had "downplayed" the health issue when he initially announced the need for surgery.
