卵巢癌是妇科领域中最恶性的肿瘤之一。对于子宫颈癌和子宫体癌的发生原因,目前个别病例尚可从流行病学观点上得到不同程度的阐明;但对卵巢癌的发生原因,则全不明确。近四十年来,卵巢癌的发病率不断增加,工业先进的国家发病率更高,其原因显然与工业的产物密切相关。其中,最引人注目的是石棉和滑石粉。早已证实石棉能成为支气管癌和间皮瘤的致病因子。另据报导:在患有石棉症的妇女中,卵巢癌的发病率明显高。滑石的成份是硅酸镁〔Mg_3(Si_4O_(10))(OH)_2〕,在日常生活中,常以其细粉作为化妆粉、防臭剂、
Ovarian cancer is one of the most malignant tumors in gynecology. For the reasons for the occurrence of cervical cancer and uterine body cancer, at present individual cases can be elucidated to varying degrees from the epidemiological point of view; but the cause of ovarian cancer is not clear. In the past four decades, the incidence of ovarian cancer has been on the increase, with a higher incidence in advanced countries, for reasons that are clearly closely linked to the products of industry. Among them, the most notable are asbestos and talcum powder. Asbestos has long been proven to be a causative agent of bronchial and mesothelioma. It is also reported that in women with asbestosis, the incidence of ovarian cancer was significantly higher. Talc is the composition of magnesium silicate 〔Mg_3 (Si_4O_ (10)) (OH) _2〕, in daily life, often with its fine powder as a cosmetic powder, deodorant,
