Brief description
This is a primary malignant neoplasm of the lung. That is the neoplasm has originated in the lung or trachea (primary) and has not migrated from another primary site (secondary or metastasis). The lung tissue includes the alveoli, bronchioles, bronchi, and trachea, but not the pleura.
Confirming the diagnosis
The diagnosis requires histology. This usually involves obtaining tissue from a biopsy of the lung. A diagnosis based on cytology can be used if biopsy and histopathology are not readily obtainable.
The appropriate medical specialist is a respiratory physician, thoracic surgeon or oncologist.

# non-SOP condition
Clinical onset
The condition may be dected incidentally on radiological imaging. Typical presenting symptoms are cough, haemoptosis (coughing blood), dyspnoea (shortness of breath) or chest pain. Patients presenting with clinical features typically have advanced disease. However, the above symptoms may all be features of other diseases. Once the diagnosis has been confirmed it may be possible to back date onset to an earlier time based on the clinical picture.
Clinical worsening
The only SOP worsening factor is for inability to obtain appropriate clinical management. Appropriate management of the disease varies considerably with the type and stage of the disease and other factors. A delay in obtaining treatment could lead to a worsening of the prognosis.
