What is lung adenocarcinoma?

Following the Vatican's announcement that Pope Leo underwent a successful surgery to remove the lower lobe of his right lung for localized lung cancer, Kaiser Permanente Oakland oncologist Dr. Jason Cham joined KTVU to explain the diagnosis and recovery outlook. Dr. Cham discussed how pathology determines cancer staging, the rise of lung cancer in non-smokers due to DNA driver mutations, and screening guidelines for high-risk individuals. He noted that while surgical recovery can range from weeks to months, targeted therapies now offer strong treatment options if further intervention is required.
