石棉怎样导致癌症?同济医科大学博士研究生毕勇毅经过3年研究得到结论:体内的Ha—ras癌基因在石棉的作用下发生突变,使癌基因激活,继而促使癌细胞发生分子生物学变异,进一步发展形成恶性间皮瘤.毕勇毅在张国高教授指导下,经过对11例由石棉引起的恶性间皮瘤组织的检测,发现有3例发生 How does asbestos lead to cancer? Tongji Medical University doctoral student Bi Yongyi after three years of research concluded that Ha-ras oncogene in vivo undergoes mutation under the action of asbestos, activates the oncogene, and then prompts cancer cells to undergo molecular biological variation. The development of malignant mesothelioma developed. Bi Yongyi under the guidance of Professor Zhang Guogao, after the detection of 11 cases of malignant mesothelioma caused by asbestos, found that 3 cases occurred
