Medical tests to detect lung cancer
Smokers with an increased risk of lung cancer should consider annual lung cancer screening. Therefore, if you’re a smoker or have any other risks for lung cancer, then this screening test will help doctors find the disease before you start noticing any symptoms. This would let the treatment start early, when the condition is easier to fight.
If the screening shows that you may have lung cancer, then the doctor will advise you for some diagnostic tests so that he/she can pinpoint the type of disease and whether it has spread to other parts of the body.
Below are the medical tests to detect lung cancer:
1) Imaging tests: An X-Ray image of your lungs may reveal an abnormal mass or nodule, whereas a CT scan can reveal small lesions in your lungs that might not be detected on an X-ray.
2) Sputum cytology: If you have a cough and are producing mucus, then this test is used to look for cancer cells in your mucus. To get a sample, you will have to breathe deeply and then cough with enough force to bring some up from your lungs and then spitting it out into a cup. Looking at this sample under a microscope can reveal the presence of lung cancer cells.
3) PET (positron emission tomography): In this test, a special type of radiation is used, that collects in cancer cells. A camera is then used to take pictures of these areas to find out if a growth that showed up on an X-ray is really cancer, and to see if it’s moved to other places.
4) Tissue sample (Biopsy): This procedure involves removing of a sample of abnormal cells to check under a microscope for cancer, and to figure out which kind it is.
Biopsy can be performed in a number of ways:
a) Bronchoscopy: For this test, the doctor removes a tissue sample through a thin tube that he/she places into your lungs.
b) Mediastinoscopy: An incision is made at the base of your neck and surgical tools are inserted behind your breastbone to take tissue samples from lymph nodes.
c) Needle Biopsy: The doctor numbs your skin and uses a needle to remove a sample of tissue. The doctor uses X-ray or CT images to guide a needle through your chest wall and into the lung tissue to collect suspicious cells.
