目前的医学研究认为造成癌症的原因有很多,如环境、饮食、遗传等,其中的遗传因素成为众多癌症病人及其家属极为关心的一个问题,经常会有一些病人问医生肿瘤会不会遗传,能不能进行预防。对于这个问题很难简单地下结论,大量医疗实践发现,遗传因素在癌症的发生过程中确实起一定的作用。一、癌症遗传的原理癌症的家族遗传现象是怎么产生的呢?目前认为,这可能是由染色体畸变造成的。正常人体每个细胞有46条染色体,各种致癌因子可以引起染色体畸变,使得染色体在数目和形态上与正常细胞不同,这种染色体的畸变有时会遗传给后代,使其下一代具有患癌的可能性。
Current medical research considers that there are many causes of cancer, such as the environment, diet, and genetics. Genetic factors among them have become a problem of great concern to many cancer patients and their families. Often, some patients ask doctors if the tumor will inherit. Can we prevent it? It is difficult to draw conclusions on this issue in a simple way. A large number of medical practices have found that genetic factors do play a role in the development of cancer. First, the principle of cancer genetics Cancer family genetic phenomenon is how it is produced? At present, this may be caused by chromosome aberrations. Normal human cells have 46 chromosomes per cell, and various carcinogenic factors can cause chromosomal aberrations, making the chromosomes different in number and morphology from normal cells. This chromosome aberration is sometimes inherited to offspring, leaving the next generation with cancer. possibility.
