Female Breast Cancer Incidence in Georgia by regions and municipalities in 2015-2019

Abstract

In 2015-2019, 29,311 (56%) cases of female cancer were registered, of which 9, 298 (31.7%) were breast cancer cases. Breast cancer ranks 1st place in the structure of cancer in the female population, both in Georgia (ASR=62.9; 95%CI= 61.6-64.2) and in Tbilisi (ASR=85.0; 95%CI=82.1- 87.8). The following is the distribution of breast cancer in female population per location according to age standardized and age adjusted ratios (ASR, AAR): upper outer quadrant holds the 1st place (ASR=14.9; AAR=28.6), upper inner quadrant is the 2nd in row (ASR=4.2; AAR=8.1), and central portion holds the 3rd place (ASR=3.3; AAR=6.3). Based on breast cancer incidence in Georgia and its regions higher than mean incidence rate in Georgia (ASR=62.9; AAR=95.7) was registered in Tbilisi (ASR=84.6; AAR=123.6) and Racha-Lechkhumi and Qvemo Svaneti region (ASR=65.7; AAR=107.2). Breast Cancer Proportional Incidence Rate (PIR) in regions versus overall rate in Georgia is 12.4% higher in Racha-Lechkhumi, 8.8% higher in Shida Kartli and 4.8% higher in Imereti. It is clear at the first glance that in order to further investigate problem of relatively high breast cancer incidence in certain municipalities it is necessary to study PIR per municipalities, especially in Racha-Lechkhumi, Shida Kartli and Imereti.
