Lung cancer screening tests are carried out to look for lung cancer early symptoms in people who have no symptoms at all. Routine screening is very reliable and can often detect even the smallest lung tissue abnormalities. This is critical because early detection will lead to better outcomes and a higher standard of living. Early detection rates continue to increase as these lung cancer tests become more accurate and accessible.
Continue the annual screening of lung cancer until you reach a point where you are unlikely to benefit from screening such as when you have certain severe health problems that could make you too weak to seek treatment for lung cancer.
The following screening tests are performed to see if they decrease the risk of lung cancer:
Low-dose spiral CT scan (LDCT scan): A technique using low-dose radiation to produce a series of very detailed images of interior body. It uses an x-ray machine which scans a spiral path of the body. The images are taken by a computer that is connected to the x-ray system. This technique is also called low-dose helical CT scan.
Chest x-ray: It takes the x-ray of internal chest organs and bones. A lung cancer x-ray is a type of energy beam that can travel through the body and create an image of areas inside the body.
Sputum cytology test: Sputum cytology in lung cancer is a process where a sputum sample is examined under a microscope to test for cancer cells.
