癌起初是个别细胞的病变,是由于细胞DNA 受到损害,使染色体不断地发生变化而形成的。绝大多数细胞对这一过程具有很强的抵抗力。是否存在一些保护基因的产物来维持基因的稳定,维持多数细胞尤其是人体细胞的正常活动呢?各种现象说明存在抑制肿瘤生长的基因。 Cancer was originally a disease of an individual cell, and it was formed because the DNA of the cell was damaged and the chromosomes constantly changed. The vast majority of cells are very resistant to this process. Is there any product that protects the genes to maintain the stability of the gene and maintain the normal activity of most cells, especially human cells? Various phenomena indicate the existence of genes that inhibit tumor growth.
