Pope Leo XIV has reportedly been diagnosed with lung adenocarcinoma after surgery to remove a nodule from his right lung at Gemelli Hospital in Rome. The news has raised concerns among Catholics worldwide as the 71-year-old pontiff begins his recovery and doctors assess whether additional treatment will be necessary.
The Vatican confirmed that the operation was completed successfully and that the pope had returned to his hospital room. However, questions remain about the cancer’s stage, his long-term prognosis, and whether his upcoming international engagements will be affected.
Doctors Confirm Lung Cancer After Surgery
The pope’s medical concerns began when doctors discovered a small, localized nodule in his right lung during medical examinations. His medical team recommended removing the abnormality to determine its nature and address the potential health risk.
On October 13, 2026, surgeons at Gemelli Hospital performed the operation. The procedure was led by Professor Stefano Margaritora, the hospital’s chief thoracic surgeon.
Doctors removed the affected portion of the lung using a video-assisted surgical technique. The operation reportedly lasted approximately 90 minutes and was completed successfully, without immediate complications.
Examination of the removed tissue subsequently confirmed lung adenocarcinoma, a common form of lung cancer.
Although the successful operation is encouraging, the diagnosis does not automatically reveal how advanced the disease is. Further medical assessments are necessary to determine whether additional treatment will be required.
What Is Lung Adenocarcinoma?
Lung adenocarcinoma is a type of non-small cell lung cancer that develops in glandular cells in the lungs. It is the most common subtype of lung cancer and can affect people who have never smoked.
The outlook depends on several factors, including the tumor’s size, whether cancer cells have spread, and the patient’s overall health.
When detected early and confined to the lung, surgery may be an effective treatment. Some patients may also need chemotherapy, targeted therapy, or other treatments depending on their individual circumstances.
In Pope Leo XIV’s case, the full prognosis has not been publicly established. It would therefore be premature to draw conclusions about his long-term recovery.
Prayers and Support for the Pope
Before the operation, medical staff reportedly gathered in the hospital chapel to pray the rosary for the pope and other patients.
Cardinal Baldassare Reina, the vicar of Rome, encouraged people to pray for Leo’s strength and for everyone receiving medical care.
Pilgrims visiting Rome also expressed concern. Some had traveled considerable distances hoping to see the pontiff, but many understood that his health needed to come first.
The pope is expected to remain in hospital for at least a week. His public engagements have been canceled through October 20 to allow time for recovery.
Will His South America Trip Go Ahead?
Leo is scheduled to visit Uruguay, Argentina, and Peru from November 6 to 17. The journey would involve extensive travel and several public appearances.
The planned visit to Peru is particularly significant because the pope spent many years serving the Catholic community there as a member of the Augustinian order.
However, his ability to undertake the trip will depend on his recovery and his doctors’ recommendations. No final decision should be assumed until the Vatican provides an official update.
What Happens Next?
Doctors will continue monitoring the pope’s recovery and evaluating the results of further examinations. These findings will help determine whether the surgery was sufficient or whether additional treatment is appropriate.
The successful operation offers an encouraging starting point, but it does not establish his long-term prognosis.
For now, the priority is his health and recovery. Catholics and people around the world are awaiting further updates and hoping that the 71-year-old pontiff will soon be able to resume his public duties.
As the world watches closely, the coming days will be important in determining what lies ahead for Pope Leo XIV.
