In Ho Chi Minh city that prevalence was 17.1 per 100,000 of the population and was the second highest cause of death in women. Objectives: To assess the value of X-ray mammography and cytopathology test for breast cancer diagnosis of early stage Tis and T1. Subjects and method: A retrospective study was conducted among 103 breast cancer patients with malignant tumor size \uf0a32cm, who were admitted to K Hospital and Thanh Nhan Hospital from 01/2003 to 02/2008.
