Pope Leo XIV made his first public appearance since undergoing surgery to remove a cancerous tumor from his right lung, addressing thousands of faithful gathered in St. Peter’s Square on Sunday. The 71-year-old pontiff appeared at a window of the Vatican’s Apostolic Palace to deliver the traditional Angelus blessing and expressed gratitude for the prayers and support he received throughout his recent health challenge.
The pope, who was diagnosed with adenocarcinoma—a common form of lung cancer—had the lower lobe of his right lung surgically removed last Tuesday at Rome’s Gemelli Hospital. Originally, the Vatican anticipated a week-long hospital stay; however, Leo was discharged on Saturday after a shorter-than-expected recovery period. During the surgery, doctors confirmed the malignant nature of the lung nodule, which was discovered incidentally during routine abdominal tests. According to his surgeon, Dr. Stefano Margaritora, the procedure was routine and without complications, and the cancer appeared to be in its early stages.
In his address, Pope Leo acknowledged the emotional impact of his illness, saying the experience had brought him closer to those suffering from illness and infirmity. He also expressed particular thanks to his medical team and hospital staff. The pope signaled a gradual resumption of his activities, pledging to continue his work with the help of God and the prayers of the faithful.
Despite concerns about his health, Leo’s surgeon stated there were “no clinical reasons” preventing the pope from undertaking his scheduled 12-day trip to South America in November, which will include visits to Uruguay, Argentina, and Peru. The journey features numerous flights and helicopter rides, some to high-altitude locations. Dr. Margaritora expressed optimism about the pope’s recovery, estimating full recuperation in approximately ten more days.
The Vatican has not yet disclosed the results of additional oncological tests, including histological and molecular analyses, which will inform whether Pope Leo requires further treatment such as chemotherapy, immunotherapy, or targeted therapies. Officials emphasized that updates on the pope’s prognosis would not be shared during his public Angelus appearances.
While Leo has maintained an active schedule in recent months and appeared physically strong prior to his diagnosis, his quick return to public appearances was seen by observers as a demonstration of resilience. Visitors to St. Peter’s Square, including pilgrims and tourists from various countries, expressed relief and joy at seeing the pope healthy and composed. During his hospital stay, the pope also continued fulfilling official duties, including a phone call to Russian President Vladimir Putin, urging a ceasefire in the Ukrainian city of Oleshky.
Pope Leo, the first pontiff born in the United States, has been known for an active lifestyle, including a passion for tennis, and was previously considered to be in good health. His recovery and upcoming engagements will continue to be closely watched by followers worldwide.
