求翻译：现代医学还认识到肿瘤、癌症是一种基因病，所有的细胞中都含有能够导致细胞癌变的基因，这些癌症基因代代相传。但在通常情况下它们处于被阻遏状态，只有当细胞内有关的调节机制遭到破坏的时候下，癌症基因才会“作恶”，导致癌变的发生。“激酶”的基因家族包括500多种不同的基因，它们功能的丧失是癌症的一个常见诱因，这些基因就像开关一样，控制着细胞的生长和死亡以及变异进程。是什么意思？

Modern medicine also recognizes that the tumors, cancer is a genetic disease, cells all contain the gene can lead to carcinogenesis, cancer genes from generation to generation. But usually they are deterring state, only if the cells under the relevant regulatory mechanism is compromised when, cancer genes would "be evil", leading to carcinogenesis. "Kinase" gene family consists of more than 500 different genes, their loss function is a common cause of cancer, these genes are like switches, control of cell growth and death, and variation of the process.
