The subject of breast cancer is reviewed with particular emphasis on the genetic aspect of its etiology. A number of studies using various approaches gave the same results: the familial form occurs earlier and there is a higher risk in female members of the breast-cancer families. An association between breast cancer and cancer of certain other sites among women is reported. Cytogenetic studies of "cancer families" revealed increased frequency of aneuploidy in some members. However, the role of chromosome abnormalities in carcinogenesis is still not clear.
本文对乳腺癌主题进行了综述,特别强调了其病因学的遗传方面。多项采用不同方法的研究得出了相同的结果:家族性形式发病更早,且乳腺癌家族中的女性成员患病风险更高。有报道称女性乳腺癌与某些其他部位的癌症之间存在关联。对“癌症家族”的细胞遗传学研究显示,一些成员中染色体数目异常的频率增加。然而,染色体异常在致癌过程中的作用仍不明确。
