The Vatican confirmed on October 13, 2026, that Pope Leo XIV underwent a planned operation at Rome’s Gemelli Hospital to remove the lower lobe of his right lung. The Holy See Press Office said intraoperative histology confirmed lung adenocarcinoma, as doctors had suspected before surgery. It reported that the operation was successful, lasted about 90 minutes and ended without complications.
What the Vatican has confirmed
The statement said the Pope woke as expected and returned to his hospital room after a short observation period. Vatican News reported that the surgery was completed as planned. These are the confirmed medical details; the cited statements did not announce a broader treatment plan or prognosis.
What adenocarcinoma means
Adenocarcinoma is a cancer that begins in gland-forming cells. The term describes the type of tumor, but by itself does not establish its stage, whether it has spread, or what treatment may follow. Those details should not be inferred from the name of the diagnosis.
What remains unknown
The Vatican’s update confirms the diagnosis and surgery but leaves important clinical questions unanswered. Claims about recovery timelines or future duties should be treated as unconfirmed unless the Holy See or medical team provides them.
