The most common histological type was invasive ductal carcinoma (95.3%). Most patients received surgical treatment (91.9%) and chemotherapy (94.2%). The overall five-year survival rate was 63%. The overall five-year survival rate in stage I, II, III and IV were 100%, 85%, 39% and 9% respectively. CONCLUSION: The peak age of breast cancer was 41-50 years old.
