Physical Examination:

When the signs and symptoms of the lung cancer start to appear in the patient, he undergoes a physical exam. A physician may demand a sample of sputum that is a matter from lungs and throat , spit out from the mouth.   This sample is tested in the laboratory to find out the presence of bacteria, other infectious organisms, or cancer cells. Sometimes the doctor comes to know about the causes of lung cancer in this exam. If this test doesn’t provides some useful information of cancer , a doctor proceeds with the other tests.

Here is detail of these:

Chest Radiograph:

It is an x-ray through which the doctor detects a localized mass in the lungs.

Computed Tomography / CT scan:

In this imaging process used in the diagnosis of Lung cancer , in which  the cross-sectional images are created with a computer attached with an x-rays machine.

MRI Scan:

Through MRI scan, the clear cut images of inside areas of body are produced with the help of a magnetic field that is linked to a computer.  The purpose of this test is  to determine the location and extent of lung cancer.

Bronchoscopy:

Bronchoscopy is performed by a Pulmonologist who is a specialist of respiratory disease. The windpipe and lung branches are examined with the mean of a flexible scope. Different tests may be combined with this test  such as biospsy; removal of tissue for microscopic examination , brushing ; a small brush-like device is employed for collection of cell from the tissue lining the respiratory system  or  cell analysis ; the washing  of respiratory tissues.

Needle biopsy:

In case the result of bronchoscopy is negative then doctor performed the needle biopsy under CT-guidance.  During fine needle aspiration (FNA), a slim hollow needle is linked to the syringe and then this syringe is inserted to the suspected mass. In order to get the sample of tissue from that mass , needle is moved  first forward and afterwards backward.

Core biopsy is administered with the mean of a large-bore needle to obtain a tissue sample for analysis.

Bone Scan:

The purpose of this scanning is to pinpoint the metastasis to the bone. In metastasis, cancerous cells break away from the tumor side and spread or growth in other parts of the body.
