[The epidemiology of cancers of the female genital organs].

According to the Vital Statistics of Japan, the age-adjusted mortality rates for cancers of the uterus (all parts), the cervix uteri, the placenta (choriocarcinoma), the vagina and the vulva, have been decreasing while those for cancers of the ovary, the fallopian tube and the corpus uteri have been increasing. The standardized mortality ratio of uterine cancer (all parts) is generally higher in the western parts of Japan and that of ovarian cancer is generally higher in the northern parts of Japan. From international comparisons, the Japanese female shows lower incidences of cancers of the ovary, the corpus uteri, the vagina, and the vulva and higher incidences of cervical cancer and choriocarcinoma.
