Radiograph: There is no blood test that will help diagnose lung cancer. A chest X-ray would be the place to start, but in the absence of symptoms (cough up blood, unexplained weight loss for example) it is not the best screening test. Recent studies in the US suggest that a screening CT scan is the way to screen for early cancers. However, your best tool is to Quit Smoking! Good luck!

Low dose chest CT: No blood test currently available to detect lung ca. Low-dose chest CT was recently endorsed to screen for lung ca in high-risk population (such as heavy smoking >30pack years).
