Before the operation, Pope Leo XIV was admitted to Gemelli Hospital in Rome after a lung nodule was discovered during routine checkups, and the Vatican announced the suspension of public audiences until October 20. The pontiff said at the time that he felt well and that he had chosen to undergo the procedure as soon as possible so as not to alter his plans.
After the operation performed on October 13 to remove the lower lobe of the right lung, recovery continued, and the Vatican issued several medical updates regarding his condition. Meanwhile, the pope canceled his scheduled visit to Assisi, with doctors recommending that he avoid traveling by helicopter during his recovery.
