Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Breast cancer has become the most common malignancy in women. Improving the early diagnosis of breast cancer can reduce mortality. Mammography is recommended as the main tool for screening and early diagnosis of breast cancer in the guidelines of European and American countries. However, the characteristics of dense breast and young onset of disease in Chinese women make the screening and early diagnosis strategies of Western countries, which are mainly based on mammography, unsuitable for Chinese women. 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.
