Lung cancer often has no symptoms until it has spread (metastasized). This is because there are few specialized nerves (pain receptors) in the lungs. When symptoms do occur, they vary depending on the type of lung cancer and location and size of the tumor. A series of tests are necessary to diagnose lung cancer. Further testing can identify the type and stage of cancer, which help determine treatment options.
