Lung Cancer Diagnosis
There are several factors taken into account to diagnose lung cancer,
such as the patient�s medical history, whether or not there is a history of
smoking and the duration, environmental or occupational exposure, and the
family�s history of cancer.� A physical
exam of the patient will need to be performed and your doctor may order a chest
x-ray.� Sputum cytology (examination of
microscopic mucus cells from the lungs after a deep cough) may be used for
diagnosis.� Most importantly, to reach a
diagnosis of lung cancer, the doctor will need to obtain a sample of tissue
from the lung to be examined under a microscope.� The tissue sampling, or
biopsy, may be performed by one or more of the below methods:
�
Bronchoscopy
Through the use of a thin,
lighted tube inserted through the mouth or nose into the windpipe to view
breathing passages, cells or small tissue samples can be collected.
�
Needle Aspiration
Through the use of a
needle inserted in the chest directly into the tumor, a sample of tissue is
removed.
�
Thoracentesis
A needle is used to
obtain a sample of fluids surrounding the lungs.
�
Thoracotomy
A major operation is
performed to open the chest cavity to obtain a sample.
