See comments by annj as I also had my left lower lung removed due to a 1.3 cm neuroendocrine carcinoid. Lymph nodes were removed and path stated clear. No symptoms prior just happened to discover in another scan 13 years ago so watched it periodically. Post-op is painful but manageable. Once the chest tube is removed, felt so much better. Historically, I am a walker so lungs were in great shape. Began walking again in increments and was feeling 'normal' after a couple of weeks.
