Abstract
Background: In recent decades the amount of new breast cancer cases in the southern region has been reported
to increase more rapidly than in the northernVietnam. The aim of this study is to compare breast cancer risk factors
between the two regions and establish if westernized influences have an impact on any reported differences. Method:
Data was collected from the two largest oncology hospitals in the north and the south of Vietnam in 2015. Breast density,
demographic, reproductive and lifestyle data of 127 cases and 269 controls were collected in the north and 141 cases
and 250 controls were gathered from the south. Baseline differences in factors between cases and age-matched controls
in each region were assessed using chi-square tests and independent t-tests. Odds ratios (OR) for independent risk
factors for breast cancer were obtained from conditional logistic regression. Results: In northern Vietnam significantly
increased risks in developing breast cancer were observed for women with age at first menstrual period less than 14
years old (OR=2.1; P<0.05), post-menopausal status (OR=2.6; P<0.0001), having less than 2 babies (OR=2.1; P<0.05).
Southern Vietnamese women having a breast density of more than 75% (OR=2.1; P<0.01), experiencing post-menopause
(OR=1.6; P<0.05), having a history of less than 3 pregnancies (OR=2.6; P<0.0001) and drinking more than a cup of
coffee per day (OR=1.9; P<0.05) were more likely to be diagnosed with breast cancer. Conclusion: We found that
women living in the south had some breast cancer associations, such as increased mammographic density and coffee
consumption, which are closer to the risks in westernized populations than women in the north.
