Pope Leo XIV appeared at the Vatican on Sunday to thank thousands of faithful gathered in St. Peter’s Square for their prayers and support during his recent hospitalization. The pontiff, who underwent surgery to remove a malignant tumor from his lung, announced that he plans to gradually resume his usual duties.

A week prior, during the traditional Angelus blessing at the same window overlooking the square, Pope Leo XIV had disclosed the discovery of a nodule on his lung and his impending surgical treatment. On Tuesday, the 71-year-old pontiff underwent an operation to remove the lower lobe of his right lung. The surgery confirmed the presence of adenocarcinoma, the most common form of lung cancer. Further treatment options are currently under consideration.

Addressing the crowd, the pope said, “Now that this delicate phase is behind me, I will gradually resume my activities, always with God’s help and your prayers.” His voice sounded strong during the address, which occurred four days after the surgery. He also expressed feeling particularly connected to those facing illness and acknowledged the support he received from the public and medical staff during his recovery.

Pope Leo XIV extended special thanks to the doctors, nurses, and hospital staff at Gemelli hospital, where he was treated. After pausing to wave to the crowd, he retreated to his apartment for continued recuperation.

Among those present, Claire Holland from Jacksonville, Florida, noted her relief and gratitude for the pontiff’s recovery, describing him as “a strong, determined man” and expressing joy that he was well enough to make a public appearance.

This health event represents the first major medical challenge in Pope Leo XIV’s 17-month tenure. The Vatican has not yet announced a detailed timeline for his full return to all papal duties.
