The Vatican confirmed the diagnosis, which was suspected by pre-operative tests, after the 90-minute procedure led by Dr. Stefano Margaritora at Rome's Gemelli Hospital. The pontiff awoke as expected and returned to his room. He is expected to remain hospitalized for about a week, with all scheduled audiences canceled through October 20. The Holy See Press Office stated the surgery was successful and completed on schedule. Pope Leo XIV had announced the discovery of a lung nodule during his Sunday Angelus address on October 11, reassuring pilgrims that it was detected at an early stage and was well-contained.
