Pope Leo XIV has lung cancer called adenocarcinoma. Here's what that means

Pope Leo XIV has been diagnosed with adenocarcinoma, the most common form of lung cancer. Following the diagnosis, the lower section of his right lung was surgically removed.

While lung cancer remains a leading cause of cancer-related mortality worldwide, medical experts note that the disease is very treatable when detected in its early stages. According to the available reports, the pope's tumor appears to have been caught early.
