VATICAN CITY — Pope Leo XIV will not require additional treatment for lung cancer after surgery successfully removed a localized tumor from his right lung, the Vatican announced Wednesday, offering encouraging news about the 71-year-old pontiff's recovery and plans to resume his duties.

The pope's personal physician, Dr. Luigi Carbone, and thoracic surgeon Dr. Stefano Margaritora said final laboratory and molecular analyses confirmed that the tumor was pulmonary adenocarcinoma and that the disease was localized. A subsequent oncology assessment determined that no further treatment was necessary, according to a statement released by Vatican officials.

The announcement followed surgery at Rome's Gemelli Polyclinic that removed the lower lobe of the pope's right lung. Leo returned to the Vatican on Oct. 17, several days after the procedure, and has since made public appearances, including the weekly general audience in St. Peter's Square on Oct. 21.

The medical update provides reassurance about the immediate treatment plan, although continued medical monitoring will remain important as the pope recovers.

Doctors Confirm Localized Lung Cancer

Pulmonary adenocarcinoma is the most common form of lung cancer, accounting for roughly 40% of cases. It develops in cells that line the small air sacs and other structures of the lungs and can occur in people who have never smoked.

The diagnosis was confirmed after doctors examined tissue removed during the operation. According to the Vatican, the findings showed that the disease was localized, allowing the medical team to conclude that no additional cancer treatment was required at this time.

Leo announced on Oct. 11 that doctors had identified a lung nodule requiring surgical removal. The disclosure surprised many observers because the pope had continued his public duties before the procedure.

The nodule was reportedly discovered during medical examinations, rather than after the pope sought treatment for obvious respiratory symptoms. Doctors decided surgery was appropriate, and the operation proceeded as planned.

In cases where lung cancer is detected early and has not spread, surgery may be sufficient treatment. Additional therapies, including chemotherapy, radiation or immunotherapy, may be considered when the disease has spread or when test results indicate a greater risk of recurrence.

The Vatican has not released every detail of the pope's medical records, so the announcement should not be interpreted as a guarantee that the cancer can never return.

Pope Leo XIV Recovery 

Leo's return to public appearances has offered a visible indication that he is resuming some of his responsibilities after surgery.

On Oct. 18, the pope delivered the traditional Sunday Angelus from the balcony of the Apostolic Palace. He spoke about his experience with illness and expressed solidarity with people facing medical difficulties.

The following Wednesday, he greeted worshippers during his general audience in St. Peter's Square and thanked people for their prayers and support.

The pope's public schedule is being resumed gradually as he continues to recover. His doctors have not indicated that additional cancer treatment is needed, but recovery from lung surgery involves more than the removal of a tumor.

Pope Leo XIV Continues Follow-up and Monitoring with Drs

Patients may need time to rebuild stamina and breathing capacity following the removal of a lung lobe. Respiratory physiotherapy, physical activity tailored to the patient's condition and follow-up imaging may form part of postoperative care, depending on individual medical circumstances.

Dr. Juanita Mora, a national medical spokesperson for the American Lung Association who was not involved in the pope's treatment, told CNN that doctors typically monitor patients after lung cancer surgery for signs of recurrence.

Follow-up plans often include CT scans at regular intervals during the first several years, followed by continued surveillance. The precise schedule depends on the patient's diagnosis, treatment and medical history.

South America Trip Remains on the Calendar

The favorable medical assessment comes ahead of Leo's planned visit to South America from Nov. 6-17. The proposed itinerary includes stops in Uruguay, Argentina and Peru.

The trip would involve numerous flights and travel between destinations, presenting additional logistical and physical demands while the pope recovers from surgery.

Although the Vatican has not definitively confirmed that every part of the itinerary will proceed as planned, Margaritora told Vatican News that he saw no clinical reason to cancel the visit.

Air Travel Could Cause Blood Clots After Surgery

Medical experts say prolonged air travel after surgery can increase the risk of blood clots, particularly when passengers remain seated for extended periods. Walking when medically appropriate, moving the legs regularly and following the treating team's advice can help reduce that risk.

Vaccination against respiratory illnesses also may be worth discussing with a physician before international travel, especially for older adults and people recovering from surgery. Decisions about vaccines and travel precautions should be based on individual medical advice.

The Vatican has not announced a comprehensive travel-related medical plan for the pontiff.

A Personal Message About Illness

The pope's diagnosis has also prompted him to reflect publicly on the experience of being a patient.

Following his return from the hospital, Leo said his illness had given him a deeper sense of closeness to people living with disease or physical limitations.

His remarks placed the medical announcement within a broader pastoral message about compassion for people facing illness, uncertainty and recovery.

The Vatican's decision to share details about the diagnosis and subsequent test results has also given the public a clearer picture of the pope's condition than is often available concerning the health of senior religious leaders.

For now, the medical team's conclusion is that no further cancer treatment is necessary. Leo is expected to continue recovering while gradually returning to his public responsibilities, with his future schedule dependent on medical guidance and the Vatican's decisions.

The latest announcement is encouraging, but ongoing follow-up will remain important as the pontiff moves beyond surgery and resumes the demands of his role as head of the Roman Catholic Church.
