POPE LEO XIV DIAGNOSED WITH LUNG CANCER, VATICAN CONFIRMS;PART OF RIGHT LUNG REMOVED

ROME — Pope Leo XIV has been diagnosed with lung adenocarcinoma, a type of lung cancer, following surgery to remove the lower portion of his right lung, the Vatican confirmed on Tuesday, October 13.

The 71-year-old pontiff underwent the operation at Rome’s Gemelli Hospital after doctors discovered a small nodule in his lung during a recent medical examination. According to a medical bulletin released by the Vatican, tissue tests conducted during the procedure confirmed the doctors’ earlier suspicions.

The surgery lasted approximately 90 minutes and was reported to have been successful, with no complications.

Following the procedure, Pope Leo regained consciousness normally and returned to his hospital room to rest. He is expected to remain at Gemelli Hospital for approximately one week while recovering.

The Vatican has canceled the Pope’s public engagements through October 20 to allow him time to recuperate. Further details about his condition, the stage of the cancer and whether additional treatment will be necessary have yet to be announced.

Lung adenocarcinoma is a common type of non-small cell lung cancer that develops in cells responsible for producing substances such as mucus. Its prognosis and treatment depend on several factors, including the stage of the disease, whether it has spread and the patient’s overall health.

The Vatican has not publicly disclosed whether the cancer has spread beyond the affected portion of the lung or provided a detailed treatment plan following the operation.

Pope Leo XIV, born Robert Francis Prevost in Chicago, became the first American to lead the Catholic Church when he was elected pope in May 2025. Before his election, he spent many years serving as a missionary and church leader in Peru.

His recovery and any subsequent medical updates are expected to determine when he can resume his public duties.
