Medical examinations confirmed Wednesday that Pope Leo XIV will not require additional treatment for lung cancer following the removal of a localized malignant growth last week. The results represent the most encouraging indication yet that the pontiff’s cancer was detected early and that prompt intervention after his first major health episode as pope has been effective, according to statements from the Vatican.

Doctors Luigi Carbone and Stefano Margaritora noted that histological and molecular analyses verified the diagnosis of pulmonary adenocarcinoma and confirmed the disease remained confined to its original site. An oncological assessment concluded no further therapy is necessary.

The Vatican announced the pope will proceed with a planned 12‑day tour of Latin America beginning November 6, visiting Uruguay, Argentina and Peru. The trip includes a stop in Cusco, a high‑altitude city that medical experts have warned could present respiratory challenges for a patient recovering from lung surgery.

Margaritora, the operating surgeon, told Vatican News that Leo’s recovery, including re‑expansion of the affected lung, is progressing as expected. He estimated full physical recovery would take roughly two weeks post‑surgery, allowing the pope to manage long‑haul flights and a demanding schedule.

Carbone added that the pope’s determination to recover quickly has been evident, requiring minimal medical assistance. While Leo remains physically active — playing tennis and swimming — oncologist Raffaele Angelo Madaio of Rome’s Israelite Hospital cautioned that removal of part of a lung combined with age may limit stamina, especially during high‑altitude activities.

After a week of public appearances, including his Angelus blessing on St. Peter’s Square, Leo addressed crowds, expressing solidarity with those facing illness. He indicated plans to gradually resume duties, supported by prayer and medical guidance.
