Methods 352 patients with breast cancer confirmed by biopsy during 18 years from 1976 to 1993 were divided into two groups of before 1985 (group 1) and after 1985 (group 2). Clinical review and analysis of the operative procedures in accordance with clinical stages were carried out. Results The prevalent age was forties, which accounts 32.4% of total. The main presenting symptoms were palpable mass (90.1%), pain and tenderness (11.4%), nipple retraction (6.5%), and nipple discharge (5.1%). The most frequent site of the breast cancer was upper outer quadrant (49.7%). The size of tumor mass displayed less than 2㎝ in 29.7%, 2-5㎝ in 37.9%, and more 5㎝ in 25.7% in Group 1, and less than 2㎝ in 46.1%, 2-5㎝ in 47.1%, and more than 5㎝ in 4.9% in Group 2 Staging according to TNM system showed that stage Ⅱ was 37.8%, stage Ⅰ 29.7%, and stage Ⅲ 18.9% in Group Ⅰ, and stage Ⅱ 46.1%, stage Ⅰ 36.3%, stage Ⅲ 12.3%, and stage zero 2.9% in Group 2. The operative procedures performed were 38.5% of radical mastectomy, 34.5% of modified radical mastectomu in Group Ⅰ respectively and 42.2% of modified radical mastectomy 23.0% of simple mastectomy. 20.6% of radical mastectomy and 14.2% of lumpectomy in Group 2 respectively.
