Lung cancer is the cancer of the lung and is a condition where a malignant tumour is present in the tissues of the lungs. The lungs are located on either side of the chest and receive oxygen from the air when we breathe and transfers it into the bloodstream. They also transfer the carbon dioxide in our body to the atmosphere when we exhale. Most lung cancer cases are caused by long-term tobacco smoking. Lung cancer may also be determined by genetic factors and exposure to various chemicals and air pollution.
A biopsy is done on suspicious tumours or growths in the lungs to check the lungs for signs of cancer.
A complete blood count blood test will be done to check for white blood cell increase which could be a sign of cancer.
Imaging tests are done with ultrasound or CT scan to check the lungs for abnormalities.
