“A nodule located in my lung”: should we be worried after the operation undergone by Pope Leo XIV?

During recent medical examinations, doctors discovered a localized nodule in my lung, Pope Leo XIV said on Sunday. It was detected at a very early stage and is well localized. Doctors believe surgery is indicated. Following their advice, I decided to have an operation to have it removed. At 71 years old, the Holy Father was operated on on Tuesday and should be hospitalized for "about a week", said a Vatican spokesperson. The operation was a success and went as planned. But what is a pulmonary nodule, and should we be worried about what happens next? How does the operation take place? Le Figaro takes stock with Professor Nicolas Roche, head of the pulmonology department at Cochin hospital, in Paris, and Professor Marie-Pierre Revel, head of the radiology department in the same establishment, vice-president of the European Society of Radiology and co-coordinator of the Impulsion* project for early detection of lung cancer.
