Lung carcinoid tumors are a rare type of lung cancer originating from neuroendocrine cells, categorized into typical and atypical tumors based on growth speed and spread potential. Most lung carcinoids are typical, growing slowly and rarely metastasizing, while atypical carcinoids grow faster and are more likely to spread. Treatment options include surgery, chemotherapy, drug treatments, and radiation therapy, with the approach depending on whether the tumors are resectable or unresectable.
