Answer:
Common tests & procedures
X-ray: X-ray of chest is taken to identify the presence of tumor.
CT scan: CT scan of the lungs is performed to identify the location and size of the tumor mass.
Magnetic resonance imaging (MRI): MRI of the lungs can detect the severity and spread of cancer cells.
Positron emission tomography (PET): To observe the function of lungs and its tissues.
Sputum cytology: Sputum tests may be performed in certain cases to look for cancerous cells.
Biopsy: A small sample of the lung tumor cells is obtained to determine if they are cancerous.
It takes about three to six months for most lung cancers to double their size. Therefore, it could take several years for a typical lung cancer to reach a size at which it could be diagnosed on a chest X-ray.
