CXR
CT Scans
MRI
Sputum cytology
Fibreoptic bronchoscopy
Transthoracic fine needle aspiration
DIAGNOSIS
RISK FACTOR: Smoking.
Radon.
Asbestos.
Air pollution .
TREATMENT :
Lobectomy.
Segmentectomy (wedge Resection).
pneumonectomy.
LOBECTOMY :It is a removal of a lobe.
1.open type
2.VATS.
PNEUMONECTOMY :
• Removal of entire lung.
1.simple pneumonectomy.
2.Extrapleural pneumonectomy. (EPP)
