The purpose of this research was to assess the ethnic and age variation in the incidence rates of cancer of the female reproductive system (cancers of the breast, cervix uteri, corpus uteri and ovaries) in Kyrgyzstan. A retrospective approach was adopted covering the period from 1995 to 2002 with descriptive and analytical methods to estimated incidence rates in women of Russian and Kyrgyz nationalities. Values were found to be higher in Russian women but decreasing over time, while increase was observed for the Kyrgyz. Breast cancers were most common in Russian women and in their Kyrgyz counterparts cancer of the cervix uteri predominated. The data reveal age and ethnic variation in cancer localization.
