Key Takeaway:
- Cancer Diagnosis: Pope Leo XIV was diagnosed with lung adenocarcinoma after surgeons removed the lower lobe of his right lung.
- Successful Surgery: The Vatican reported no complications, with the Pope recovering under medical supervision.
- Further Treatment Unclear: Doctors will assess the findings to determine whether additional treatment is needed.
The Pope Leo XIV lung cancer diagnosis has been confirmed after surgeons removed the lower lobe of his right lung at Rome’s Gemelli Hospital on Tuesday, with the Vatican reporting a successful operation without complications.
Doctors Confirm Cancer After Removing Lung Tissue
The 71-year-old pontiff has lung adenocarcinoma, a common type of lung cancer, according to a Vatican medical bulletin released Tuesday. Tissue examinations during surgery confirmed the diagnosis that doctors had suspected following earlier medical tests.
The operation lasted approximately 90 minutes, although the pope spent about three hours in the operating room. Surgeons used a video-assisted technique to remove the lower lobe of his right lung in an effort to eliminate the cancerous tissue.
“The surgery was successful, and there were no complications,” the Vatican said in its statement.
After the procedure, Leo regained consciousness normally and returned to his hospital room following a brief observation period. Vatican officials said he was recovering under medical supervision and was expected to remain hospitalized for approximately one week.
The Vatican has not disclosed the tumor’s size, its precise stage, or whether cancer cells have spread to nearby lymph nodes. Those findings will be important in determining the extent of the disease and whether additional treatment is necessary.
Pope Had Announced Surgery Before Diagnosis
As part of the Pope Leo XIV Lung Cancer news, Leo disclosed on Sunday that doctors had discovered a small, localized nodule in his lung during recent medical examinations. He said doctors recommended removing it and described the growth as having been detected at an early stage.
“During some recent medical examinations, the doctors found a small, localized nodule in my lung,” the pope said, according to Vatican News. He added that he had decided to follow medical advice and undergo surgery.
At the time of that announcement, the precise nature of the nodule had not been confirmed publicly. The cancer diagnosis became known after surgeons examined the removed tissue during Tuesday’s operation.
The diagnosis marks a significant health development for Leo, who became the leader of the Roman Catholic Church in May 2025. He was born Robert Prevost in Chicago and is the first U.S.-born pope.
The Vatican has canceled the pope’s public engagements through Oct. 20 to allow time for his recovery. His planned trip to South America in November could also be affected, although no final decision about the journey has been announced.
Recovery And Further Tests Will Guide Treatment
Lung adenocarcinoma develops in cells that line the lungs and is the most common form of lung cancer. Its outlook varies according to factors including the stage at diagnosis, whether the cancer has spread, and the patient’s response to treatment.
Surgery can be an effective treatment when cancer remains localized, but the available information does not establish whether the pope’s cancer has been completely removed or whether further treatment will be required.
Doctors are expected to conduct additional examinations of the removed tissue to help assess the disease. The Vatican has not announced a treatment plan beyond the surgery or provided a specific prognosis.
Pope Leo XIV Lung Cancer recovery will be monitored by his medical team during his hospital stay, while further updates from the Vatican are expected to clarify his condition and next steps.
The diagnosis has drawn international attention because of the pope’s public responsibilities and the potential implications for his schedule. For now, his immediate priority is recovery from surgery as doctors evaluate the findings and determine whether additional care is needed.
