[Lung cancer screening--present status and the problems].
For the counter measure having been indicated against increasing mortality rate in lung cancer cases, indication of lung cancer screening was started in 1987 in line with the law of insurance established for old aged people. In order to decrease the death rate in cases with lung cancer, methods of the counter measure were established for early detection of lung cancer by Chest X-ray and sputum cytology as well as early operative indication. Although results of these procedures have suggested effectiveness attained by mass screening, standard of efficiency have not been same in all the areas, where the screening having been performed, but there has been difference between respective areas, therefore, in order to make the every result of mass screening carried out in areas similar, it is necessary to make the indication of mass screening being done with careful attention for lung cancer cases.
