近年来,生产性粉尘的致癌和辅癌作用在职业医学研究中受到重视,尘肺和肺癌的关系也引起注意。肺癌不但会加速尘肺病变的恶化,而且也是尘肺患者死亡的主要原因之一。国内外经大量的动物实验和流行病学研究,发现生产性粉尘如石棉、某些金属和放射性粉尘有致癌作用。因此,做好粉尘作业工人的肺癌防治工作,这对保护工人的健康有着十分重要 In recent years, the carcinogenic and para-cancerous effects of productive dust have received much attention in occupational medical research. The relationship between pneumoconiosis and lung cancer has also drawn attention. Lung cancer will not only accelerate the deterioration of pneumoconiosis, but also one of the major causes of pneumoconiosis deaths. At home and abroad by a large number of animal experiments and epidemiological studies, found that productive dust such as asbestos, some metals and radioactive dust carcinogenic.
