Pope Leo XIV does not need any further treatment after lung cancer surgery, his doctors said Wednesday, October 21, according to the BBC, CBS News, NBC News and Fox News.

Tests on tissue taken out in surgery confirmed a common type of lung cancer, the outlets reported. It is called lung adenocarcinoma. The disease was localized, his doctors said.

No more therapy is needed, the doctors said after a cancer review, according to CBS News and NBC News.

The statement came from his doctor, Luigi Carbone, and his surgeon, Stefano Margaritora, NBC News and Fox News reported.

The 71-year-old had surgery on October 13 at Rome's Gemelli Hospital, the BBC and Fox News reported. Doctors removed the lower lobe of his right lung in an operation that lasted about 90 minutes, the BBC and CBS News said.

The tumor was found by chance during a routine exam, Margaritora said, according to CBS News.

The pope left the hospital Saturday, four days after surgery, the outlets reported. He held his weekly general audience in St. Peter's Square on Wednesday, the BBC and CBS News reported.

"This experience has made me feel particularly close to all those who are living with illness or infirmity," Leo said, according to CBS News.

He is still set to leave on November 6 for a 12-day trip to Uruguay, Argentina and Peru, NBC News reported.

Margaritora said there were "no clinical reasons" the trip should not go ahead, NBC News reported. The trip will cover 19,000 miles, with a stop in the high mountain city of Cuzco, NBC News said.

Before he left the hospital, Leo visited the children's cancer ward, Fox News reported. Young patients there had sent him letters, it said.
