Brief Summary

Improving the early diagnosis of breast cancer can reduce mortality. With mammography as the main tool for screening early breast cancer, the characteristics of dense breast and young onset of disease in Chinese women lowers the efficiency. The aim of this prospective study was to compare which method, x-ray or ultrasound, is more appropriate for screening and early diagnosis of breast cancer in Chinese women.
