What is it about?

Breast cancer is the most common cancer diagnosed among women in China Breast density describes the amount of fibrous and glandular tissues within the breasts and visually shows as ‘white’ on an x-ray image. Breast density is consistently proven to be an independent and important risk factor of breast cancer and people with higher breast density have a 2-6 times risk of breast cancer compared to women with lower density. However current knowledge around breast density is largely based on women from western countries, and little attention has been paid to women in China. This study therefore provided data that will improve our understanding of predictors of breast density for Chinese women using an automatic measurement.

Why is it important?

This is the first time that breast density was measured by a quantitative method for women in China and identified associations should be useful to health policy makers who are responsible for introducing effective models of breast cancer prevention and diagnosis.


I hope this article makes people think that not all the scientific-based results from western countries can be applied to Chinese population. We need studies using appropriate samples to test whether the western-based data fit the Chinese population.
