Pope Leo has been diagnosed with lung cancer following a successful surgery to remove a nodule from his lung, the Vatican announced on Thursday. The operation, carried out at the St. Gabriele Hospital in Rome, was deemed complete and the patient is now undergoing a course of chemotherapy and radiation.
The Vatican spokesperson, Father Marco Rossi, confirmed that the nodule was malignant but that the surgical margins were clear. "We are grateful for the swift and expert care of the medical team," Rossi said. The pope is expected to remain in the hospital for a short period before returning to his duties.
Pope Leo issued a brief statement expressing gratitude for the prayers of the faithful and the support of the medical staff. Several Catholic leaders, including the Archbishop of Milan, called for continued prayers and emphasized the importance of maintaining faith during illness. The diagnosis raises questions about the papal schedule and the possible need for an interim administrator.
The Vatican has not yet outlined a succession plan, but officials assured that the pope’s responsibilities will be managed to ensure continuity of the Church’s operations. Historically, several popes have faced serious health challenges, yet the Vatican has maintained a tradition of transparency regarding the health of its leaders. Pope Leo’s papacy, which began in 2025, has already seen significant reforms in the Church’s engagement with global social issues.
Medical experts say that early detection and a combination of surgery, chemotherapy, and radiation offer a hopeful outlook, though the prognosis depends on the cancer’s stage and the pope’s overall health. The Vatican has pledged to keep the faithful updated on the pope’s condition as treatment progresses.
