VATICAN CITY, October 14, 2026 — Pope Leo XIV has been diagnosed with lung cancer after undergoing successful surgery at Rome’s Agostino Gemelli University Hospital, where doctors removed the lower lobe of his right lung to treat a cancerous growth, according to a Vatican medical statement.
The 71-year-old pontiff underwent the procedure on Tuesday, October 13, after a localized lung nodule was detected during medical examinations. The Vatican subsequently confirmed that tissue analysis identified pulmonary adenocarcinoma, a form of lung cancer.
Doctors reported that the operation was completed without complications and that the pope regained consciousness normally before returning to his hospital room. The Vatican has not publicly disclosed the cancer’s stage or confirmed whether it had spread beyond the affected lung tissue.
Pope Leo XIV’s Surgery Completed Successfully
The pope underwent surgery at Gemelli Hospital, a major medical facility in the Italian capital that has treated several previous popes.
According to the Vatican’s medical update, the procedure lasted approximately 90 minutes, although the pope spent around three hours in the operating room. Surgeons used a video-assisted technique to remove the lower lobe of his right lung, with the aim of removing the cancerous tissue.
An examination of the tissue during surgery confirmed the suspected diagnosis of pulmonary adenocarcinoma.
The Vatican said the procedure went as planned and that the pontiff returned to his room following the operation. The successful completion of surgery is an important development, although further medical information would be needed to determine the extent of the disease and whether additional treatment is necessary.
What Is Pulmonary Adenocarcinoma?
Pulmonary adenocarcinoma is a type of lung cancer that develops in glandular cells within lung tissue. It is one of the most common forms of lung cancer.
A lung nodule is a small area of abnormal tissue detected through medical imaging. Such nodules can be benign or cancerous, which is why doctors may recommend further testing or removal when findings raise concerns.
In Pope Leo XIV’s case, the Vatican said that laboratory examination of the removed tissue confirmed the cancer diagnosis during surgery.
The precise stage of the pontiff’s cancer has not been publicly established in the reports reviewed. Information about tumor size, lymph node involvement and possible spread can help doctors determine prognosis and whether further treatment is needed.
It would therefore be premature to draw conclusions about his long-term outlook based solely on the successful operation.
Vatican Cancels Papal Engagements During Recovery
The Vatican has canceled Pope Leo XIV’s public audiences through October 20 as he recovers from surgery. He is expected to remain under medical care at Gemelli Hospital for approximately a week, according to earlier Vatican announcements.
The temporary suspension of public engagements allows the pontiff time to recover while medical professionals monitor his condition.
The development also affects the pope’s participation in Vatican activities, including meetings and religious events that had been planned for the coming days.
Church officials and Catholic communities around the world have expressed support and offered prayers for his recovery.
Will Pope Leo XIV Travel to South America in November?
The pope is scheduled to visit Uruguay, Argentina and Peru from November 6 to 17. However, questions remain about whether he will be able to undertake the planned trip following lung surgery.
The visit is particularly significant because Leo XIV previously served as a missionary and bishop in Peru, where he developed longstanding connections with local Catholic communities.
His medical team’s assessment of his recovery, together with any additional treatment requirements, will be important in determining whether the international journey can proceed as scheduled.
As of the latest reports reviewed, the Vatican had not confirmed a final decision on the trip.
What Happens Next in the Pope’s Treatment?
The immediate priority is the pope’s postoperative recovery. Doctors will also need to evaluate the available pathology results and other clinical findings to determine whether the surgery has removed all the cancer and whether additional treatment should be considered.
The Vatican has confirmed the diagnosis but has not released enough information to establish the cancer’s stage or provide a definitive long-term prognosis.
Further updates from the Holy See Press Office are expected to clarify his recovery and any changes to his public schedule.
A Major Health Development for the Catholic Church
Pope Leo XIV, elected in May 2025, leads the Roman Catholic Church, which has approximately 1.4 billion members worldwide. His health is therefore a matter of considerable interest to Catholics, religious leaders and observers around the world.
Although the successful operation provides an encouraging immediate update, the confirmed cancer diagnosis raises questions about the pontiff’s recovery, future medical care and upcoming commitments.
For now, the Vatican has confirmed that the surgery was completed successfully and that the pope returned to his hospital room after regaining consciousness normally.
Conclusion: Pope Leo XIV has undergone successful surgery in Rome after doctors confirmed pulmonary adenocarcinoma in his right lung. His recovery is continuing under medical supervision, while the cancer’s stage, any need for additional treatment and the status of his November travel plans remain unresolved in the latest reports.
