Pope Leo XIV will not need any further treatment for lung cancer after tests determined that the disease was localized, the Vatican said on Wednesday. 

Leo, 71, had part of one lung removed last week, and the surgery determined that he had adenocarinoma, the most common type of lung cancer, the Associated Press reported. 

The pontiff's recovery progressed well following the procedure, which took about 90 minutes. He started to walk and has "resumed a normal diet" on Oct. 14, according to doctors. 

Final tests of tissue removed during the surgery determined the cancer had not spread, according to the pope's personal physician, Dr. Luigi Carbone, and his surgeon, Dr. Stefano Margaritora.
