Pope Leo pledges gradual return to duties after cancer surgery

Pope Leo XIV signaled a measured return to public life on Sunday, Oct. 18, 2026, telling a gathered crowd in St. Peter's Square that he would gradually resume his activities following major surgery to remove a cancerous tumor from his right lung. The appearance marked his first public engagement since doctors operated on the pontiff.

According to reporting from The Irish Times, the pontiff appeared unaided at the window of the Vatican's Apostolic Palace on Sunday, Oct. 18, 2026, to deliver his traditional Angelus blessing. Greeting thousands of pilgrims under cloudy skies, his voice sounded strong as he addressed the faithful, according to Wuky.

"Now that this delicate phase has passed … I will gradually resume my activities, always with the help of God and your prayers,"

The health crisis began unfolding when a small nodule was discovered on the pope's lung, initially revealed during the previous Sunday's address. Medical professionals at Rome's Gemelli hospital performed surgery on Tuesday, removing the lower lobe of his right lung. Subsequent histological testing confirmed the mass was adenocarcinoma, the most common type of lung cancer. Surgeon Stefano Margaritora explained to Channel NewsAsia that the tumor was discovered by chance during a routine abdominal X-ray that captured the spot at the base of the lung.

The pontiff was discharged from the hospital on Saturday, following blood tests and a chest X-ray that morning. Although the Vatican had originally anticipated a weeklong hospital stay, doctors deemed him fit to leave earlier. Even from his hospital bed, the pope maintained a level of engagement, placing a phone call on Friday to Russian President Vladimir Putin to urge a ceasefire in the Russian-occupied Ukrainian city of Oleshky.

Attention has quickly turned to the pontiff's demanding travel schedule. Questions had been raised over whether the Chicago-born pope could manage a planned trip to South America, including visits to Uruguay, Argentina, and Peru, scheduled for Nov. 6–17, 2026. However, Dr. Margaritora told Vatican News that there are no clinical reasons to prevent the journey, noting that the pope put his heart and soul into his recovery, according to The Irish Times. Margaritora estimated that the pontiff would achieve a full recovery from the operation in another ten days or so, reported by The Irish Times and Channel NewsAsia.

What Happens Next

Medical teams are still analyzing histological test results from the tumor and related lymph nodes. The molecular and genetic profile of the tissue will dictate whether the pontiff requires additional medical interventions, such as chemotherapy, immunotherapy, or targeted oral therapies, noted by WUKY.
