4..in his early 20s

In 1957, in his early 20s, Jorge Mario Bergoglio underwent surgery in his native Argentina to remove a portion of his lung that had been affected by a severe respiratory infection.

As he aged, Pope Francis frequently suffered bouts of respiratory illnesses, even cancelling a planned visit to the United Arab Emirates in November 2023 due to influenza and lung inflammation.
In April 2024, the late Pope Francis approved an updated edition of the liturgical book for papal funeral rites, which will guide the funeral Mass, which has yet to be announced.
