关于恶性肿瘤细胞的本质现在在认识上未见得达到一定的深度。作者等认为,正常细胞在异常环境下反复进行细胞分裂的过程中,多数正常细胞产生各种各样的变异细胞(deviated cell),从中就可发生癌细胞。亦即可把癌细胞看作是一种正常细胞的变异株。同时,这种癌细胞在反复增殖过程中和正常细胞一样它本身也发生种种变异。作为癌细胞特征的细胞多形性(polymorphism)被认为是癌细胞增殖过程中变异结果所产生的。作者等将如此发生的 The nature of malignant cells has not yet reached a certain depth in understanding. The authors believe that normal cells in the process of repeated cell division under abnormal circumstances, most normal cells produce a variety of deviated cells, from which cancer cells can occur. Cancer cells can also be considered as a variant of normal cells. At the same time, this kind of cancer cell also undergoes various variations in the process of repeated proliferation as it does in normal cells. Cellular polymorphism, which is characteristic of cancer cells, is thought to result from mutations in the proliferation of cancer cells. Authors will happen this way
