Pope Leo XIV has been diagnosed with lung adenocarcinoma after undergoing surgery to remove the lower lobe of his right lung at Rome’s Gemelli Hospital. The Vatican confirmed the diagnosis following tests that had raised suspicions of cancer before the operation.
The 71-year-old pontiff underwent the procedure to remove a localised nodule detected during preoperative examinations. The Vatican said the three-hour procedure had concluded without complications.
The Pope is expected to remain under medical observation as he recovers from the operation. Further assessments will help doctors determine the next steps in his treatment.
Cancer diagnosis confirmed
According to the Vatican’s medical bulletin, an examination of the removed lung tissue confirmed lung adenocarcinoma, a form of lung cancer that develops in glandular cells.
Doctors removed the lower lobe of the Pope’s right lung after preoperative tests detected a localised nodule. The operation was aimed at removing the affected tissue.
The diagnosis follows the detection of the nodule during medical examinations before surgery. The Vatican has not announced the stage of the cancer or provided details about whether additional treatment will be required.
Vatican provides update on Pope's condition
The Vatican said the procedure had concluded without complications. The Pope remains under medical supervision as he recovers at Gemelli Hospital.
Doctors are expected to assess his recovery and review further medical findings before deciding on any additional treatment. The duration of his hospital stay will depend on his condition and progress following the operation.
Upcoming engagements under review
The diagnosis has raised questions about the Pope’s upcoming public engagements and international travel plans. Any changes to his schedule are likely to depend on medical advice and his recovery.
Pope Leo XIV, born Robert Francis Prevost in Chicago, was elected head of the Catholic Church in May 2025. His diagnosis marks a significant health development during his papacy.
The Vatican has not yet provided further details about the cancer’s stage or outlined a treatment plan beyond the surgery. The pontiff will remain under medical observation as doctors assess his condition and determine the next steps in his care.
