This clinical study was performed on 15 cases of breast cancer and 49 cases of benign breast disease which were confirmed by pathology and preoperative mammography was taken during the period from July 1989 to June 1990.
The results were as follows :
1. Among the breast CA(carcinoma), the most prevalent age group was fourth & fifth decades and mean age was 46 years. benign breast disease, the popular age group was third decades and mean age was 35 years.
2. Among the breast CA chief complaints were palpable mass(80%), and pain(20%). In benign breast disease, chief complaints were palpable mass(82%) and mass(18%).
3. Many of the breast CA revealed cases with 2-5cm sized mass were 23cases(80%).
4. In benign disease, cases with less than 5cm sited mass were 42cases(86%).
5. In breast CA, locations of tumor were OUQ(53%), IUQ(20%), OLQ(13%), central(13%) area, In benign disease, they were OUQ(39%), IUQ(31%), central(8%), ILQ(8%), others(8%).
6. The efficacy of mammography to detect breast CA. was as followed : sensitivity was 73%, specificity was 87% and positive predictive value was 64%.
