The Vatican announced that Pope Leo has been diagnosed with lung cancer following surgery to remove a lung nodule, during which doctors removed the lower lobe of his right lung.

Lung adenocarcinoma, which Pope Leo XIV was diagnosed with on Tuesday, is a common form of lung cancer that can be highly treatable when caught early.

Leo, 71, was admitted to Rome’s Gemelli hospital on Tuesday for surgery on Tuesday to remove a growth on his lung that doctors found in a recent health checkup.
