Why Pope Francis Only Has One Lung

Pope Francis is a pioneering pontiff in many ways — he’s the first to take the name of Francis, the first pope from South America, and the first to don the papal robes with one lung.

According to the Associated Press, the new Pope had one of his organs removed as a teenager, presumably after a bout with an infection. At that time, it’s possible that antibiotic treatments that are commonly used today to treat such infections were not as available, and to protect patients from further health problems doctors removed the lung as way to stop the infection from spreading.

“It was probably a pretty bad infection, and maybe even an abscess, that might have caused him to bleed,” says Dr. John Belperio, association professor of pulmonary and critical care medicine at the David Geffen School of Medicine at University of California Los Angeles. “If he were bleeding a lot in the lung, the only thing to do is to resect the lung, take it out, to stop the bleeding.”
