人体肿瘤的遗传问题,国内外都十分关注,也进行了大量的实验和调查,但尚未最后定论。在动物实验上,研究资料表明动物的肿瘤与遗传是有关系的。目前已能够培育出“高发癌系”和“低发癌系”的动物种群,为动物肿瘤的遗传问题提供了可靠的依据。在人类肿瘤中视网膜母细胞瘤、肾母细胞瘤、神经纤维瘤等被认为有明显的遗传倾向。近年来,越来越多的临床资料和流行病学资料证明,人体肿瘤确有家族倾向。如山西和 The genetic problems of human tumors are of great concern both at home and abroad. A large number of experiments and investigations have also been conducted, but it has not yet been finalized. In animal experiments, studies have shown that animals’ tumors are related to heredity. At present, it has been able to breed animal populations with “highly-carcinogenic” and “low-cancer” lines, providing a reliable basis for animal genetic problems. In human tumors, retinoblastoma, nephroblastoma, neurofibroma, and the like are considered to have a clear genetic predisposition. In recent years, more and more clinical data and epidemiological data have proven that human tumors do have a family tendency. Such as Shanxi and
