Are lung cancer markers accurate?

Lung cancer markers are not absolutely accurate, they have certain reference significance, and the specific accuracy also depends on the growth rate of the markers to determine.
Whether lung cancer marker is accurate or not, first of all, we have to consider the growth rate of lung cancer marker, some inflammation will also lead to the increase of lung cancer marker, such as pneumonia, but the growth rate is not big, in this case, lung cancer marker is not accurate in determining lung cancer because of the inclusion of more situations, but if the growth rate is more than several times or even more than ten times, then its judgment of lung cancer will be more accurate.
The gold standard of tumor diagnosis is pathology, which can be basically determined by cytology examination, so patients can go to the hospital for cell biopsy before making judgment, and meanwhile, do regular review to avoid delaying treatment.
