Pope Leo XIV has been diagnosed with lung cancer after undergoing surgery to remove the lower lobe of his right lung at Gemelli Hospital in Rome, the Vatican has confirmed.
The 71-year-old pontiff underwent the procedure on Tuesday, October 13, 2026, after doctors discovered a suspicious nodule in his lung during medical examinations. According to a medical bulletin released by the Vatican, an examination of the tissue during surgery confirmed that the growth was pulmonary adenocarcinoma, a common type of lung cancer.
The operation, which lasted approximately 90 minutes, was performed using a video-assisted surgical technique to remove the affected portion of the Pope’s right lung. The Vatican described the procedure as successful, stating that there were no complications.
Following the operation, Pope Leo regained consciousness normally and returned to his hospital room after a brief period of observation.
The pontiff had earlier disclosed that doctors discovered a small, localised lung nodule during recent medical examinations. He subsequently announced that he would undergo surgery on the advice of his medical team.
Before the operation, the Vatican said the growth had been detected at an early stage and was well localised. However, further medical evaluations are needed to establish the full extent of the disease and determine whether additional treatment will be necessary.
The Pope is expected to remain at Gemelli Hospital for approximately one week to recover. His public engagements have been suspended until October 20 as he recuperates.
Pope Leo XIV, born Robert Francis Prevost in Chicago, became head of the Catholic Church in May 2025 following the death of Pope Francis.
His diagnosis has drawn international attention, with Catholics and other well-wishers expressing concern and offering prayers for his recovery.
Although the surgery was completed successfully, the Vatican has not provided a definitive long-term prognosis. The outcome of further medical assessments will help determine the next steps in his treatment.
The development marks a significant health challenge for the pontiff as he continues his responsibilities as leader of the world’s Catholic Church.
For now, attention remains focused on his recovery following the operation and the results of subsequent medical evaluations.
