父亲或母亲患有癌症,父母总想知道自己的孩子会不会将来也有患上同样癌症的危险,要想弄清楚这个问题,首先要看是不是家族性肿瘤,因为带有遗传性的癌症主要来自家族性肿瘤。那么家庭性肿瘤与遗传究竟有怎样的关联呢? 我们知道,与肿瘤发生和发展相关的基因大致分成两类,一类叫抑癌基因,即抑制癌症生长的基因,当这种基因失去活性时就会发生肿瘤,另一类叫癌基因,这类基因和抑癌基因刚好相反,当它的活性增加时就引起癌
The father or mother has cancer. Parents always want to know if their child will also have the same risk of cancer in the future. To figure this out, the first thing to look for is whether it is a familial tumour because the genetic cancer is the main cause. From familial tumors. So what is the relationship between family tumors and genetics? We know that the genes involved in tumorigenesis and development are roughly divided into two categories. One is called the tumor suppressor gene, that is, the gene that inhibits the growth of cancer, when the gene is inactive Tumors occur, and the other is called oncogenes. These genes are just the opposite of tumor suppressor genes. When they increase in activity, they cause cancer.
