NSCLC is often insidious, producing no symptoms until the disease is well advanced. Early recognition of symptoms may be beneficial to outcome.

At initial diagnosis, 20% of patients have localized disease, 25% of patients have regional metastasis, and 55% of patients have distant spread of disease. Symptoms depend on the location of cancer. [1]
