US Bishops, Lawmakers Pray for Pope Leo After Cancer Diagnosis
Confirmed
In Short: The U.S. Conference of Catholic Bishops urged the faithful to pray for Pope Leo XIV after he underwent surgery for lung cancer.

The 71-year-old pontiff disclosed during his Oct. 11 Angelus address that doctors had found a “localized nodule” in his lung, detected at a very early stage.
Doctors at Gemelli Hospital removed the lower lobe of Pope Leo’s right lung, confirming the diagnosis of lung adenocarcinoma.
In a joint statement, Dr. Stefano Margaritora, chief thoracic surgeon at Rome’s Gemelli Hospital, and Dr. Luigi Carbone said the examination confirmed the diagnosis of lung adenocarcinoma, as suspected by preoperative tests.
