Pope Leo XIV underwent a procedure at Agostino Gemelli University Hospital in Rome to remove a small nodule on his lung Tuesday, the Vatican said.
The 71-year-old pontiff underwent thoracic surgery to remove the lower lobe of his right lung and doctors confirmed he had lung adenocarcinoma, a form of lung cancer, according to a statement released by the Holy See Press Office.
The diagnosis was confirmed through a tissue examination conducted during the operation, consistent with findings from preoperative tests, the Vatican said.
The pope spent approximately three hours in the operating room, although the surgery itself lasted about 90 minutes.
Doctors said the procedure was successful and there were no complications.

Leo awoke normally following surgery and, after a brief observation period, returned to his room on the hospital's 10th floor, according to the statement from Dr. Luigi Carbone and Professor Stefano Margaritora.
"Doctors found a small lump in the lung," Leo said after an Angelus address at St. Peter's Square on Monday. "It was identified at a very early stage and well situated."
"The doctors consider it appropriate to intervene and so, following their advice, I decided to have surgery to remove it," he continued. "The surgery is already scheduled for the next few days. I thank you for your spiritual closeness and I rely on your prayer."
The Vatican's latest statement confirmed that the surgery involved the removal of the lower lobe of the pope's right lung using a video-assisted technique.

Leo regularly plays tennis and swims at the papal summer retreat in Castel Gandolfo, according to The Associated Press.
Archbishop Ronald Hicks of New York offered his support to the pope, saying that the Holy Father is "in our prayers."
"We thank God that the surgery on Pope Leo was, by all accounts, successful, and that he continues his recovery and recuperation," Archbishop Hicks said. "I know that I join with people from all corners of this archdiocese, across the country, and around the world in keeping the Holy Father in our prayers."
The pope is also scheduled to embark on a major international trip from Nov. 6–17, with planned stops in Uruguay, Argentina and Peru. It remains unclear whether his surgery and recovery will affect those travel plans.

In addition to addressing his health, Leo used his Sunday remarks to renew his appeal for peace in war-torn Ukraine, warning that the conflict continues to inflict suffering far beyond the country's borders.
"The war in the martyred Ukraine continues to create suffering, even beyond its borders, especially in the poorest countries, where many people depend on the exports of cereals and grains," the pope said.
