Breast cancer incidence and mortality in Kazakhstan are considered to be increasing but exact statistics have hitherto been lacking. The present study was therefore undertaken to retrospectively assess data for the whole country, accessed from the central registration office, for the period 1999-2013. Age standardized data for incidence and mortality were generated and compared across age groups. It was determined that during the studied period 45,891 new cases of breast cancer were registered and 20,122 women died of this pathology. Average breast cancer incidence and mortality were 37.9±1.10/105 and 16.7±0.20/105 respectively, and the overall ratio of mortality/incidence (M/I) was 0.44. Incidence tended to increase (T = + 2.3%), and mortality to decrease (T of =-0.3%). Peaks of incidence and mortality were noted in those aged 60-74 years and 75-84, respectively. Particularly high incidences were established in large cities of Kazakhstan, Astana (46.8±1.80/105) and Almaty (49.7±1.30/105), and high mortality was observed in the Pavlodar region (17.9±0.60/105) and Almaty city (20.1±0.40/105). Considerable variation in the mortality/incidence ratio was noted, suggesting the need for more stress on access to screening and clinical care e in some regions of the country.

While mammography has been used for diagnosis of breast cancer in Kazakhstan for a long period, published data are very limited. Recently stress has been placed on increasing the accuracy by double reading of mammograms. Here we provide an overview of breast cancer screening in the different regions of Kazakhstan with data on the stages of cancers detected. A total 459,816 women aged 50, 52, 54, 56, 58 and 60 years were screened in 2012 and 379,903 in the first 9 months of 2013. Clear differences in levels of detection were noted between urban and rural residents, the latter demonstrating lower rates for both screening and cancer detection. Women aged 50 were more likely to undergo screening than their counterparts aged 60. While there were no clear relationships evident between screening rates and stage or numbers of breast cancers observed, this might be due to a number of complicating factors like geographical variation in risk factors as well as ethnicity. Future analyses should focus on the efficacy of mammography in Kazakhstan to reduce mortality.
