Pope Leo XIV thanked thousands of faithful in St. Peter's Square on Sunday for their prayers while he was hospitalized for an operation to remove a malignant tumor, and said he plans to gradually return to his usual duties. The crowd erupted in cheers when the pontiff showed himself in the window overlooking the square, where a week ago on the same occasion of the traditional Angelus blessing he revealed that a nodule had been located on his lung, and that it would be surgically removed.
