Pope Leo XIV Diagnosed With Lung Cancer

The Vatican has confirmed the diagnosis of Pope Leo XIV with lung cancer following a surgical procedure on Tuesday aimed at the removal of the lower lobe of his right lung.

The Pope’s diagnosis was identified as lung adenocarcinoma, following examinations that indicated the possibility of malignancy prior to surgery. The procedure was conducted over a duration of three hours, with the surgical operation itself lasting approximately 90 minutes. A statement released by the Vatican confirmed, "The operation was successful and there were no complications."

According to the Lung Cancer Foundation of America, lung adenocarcinoma is recognized as the predominant form of lung cancer in the United States, accounting for about 40 percent of all lung cancer diagnoses.

Currently, the Vatican has not provided details regarding the stage of the cancer or the potential for additional treatment for the Pope.

Public Announcement

On Sunday, Pope Leo XIV made the public disclosure of his impending surgery. Speaking to those assembled in St. Peter's Square during the Angelus prayer, the pontiff remarked, "Dear friends, during some recent medical examinations, the doctors found a small, localized nodule in my lung." He noted the nodule was detected at a very early stage and described it as well-localized. "The doctors believe that it is best to intervene, so, following their advice, I have decided to undergo surgery to remove it. The operation is already scheduled to take place in the coming days," he added.

He also expressed gratitude for the support of the public, stating, "I thank you for your spiritual closeness and entrust myself to your prayers." At that point, it was not disclosed whether the nodule was cancerous.

Recovery and Future Plans

Following the surgery, the Vatican has indicated that Pope Leo XIV will remain hospitalized for approximately one week, likely at Rome's Gemelli Hospital, which features a designated apartment for the Pope's use. During this recovery period, the Vatican will continue its operations as normal; however, decisions requiring the Pope's personal input or approval may be postponed.

The Pope is projected to undertake a visit to South America on November 6, during which he plans to travel to Uruguay, Argentina, and Peru over an 11-day span. Nevertheless, there is uncertainty regarding whether the Pope’s surgery and subsequent recovery period may result in a delay of this planned trip.
