T2: 4cases T3:2cases T1: 1case Tis: 2cases
5) In the operation method, modified radical mastectomy was performed 88%(7cases), wide excision was 12%(2cases)
6) In the pathologic classification, infiltrating ductal carcinoma was 56%(5cases), intraductal carcinoma 2cases, mucinous carcinoma 1 cases, papillary carcinoma 1case.
7) In the stage(AJCC, 1988), stage Ⅱwas 44%(4cases), stage Ⅲ2cases, stage I: 1case, stage 0:2cases
8) In the follow-up 3 patients died after 20 months, 5years, 11years survival, each cause of death, was recurrence and distant metastasis, sudden aneurysmal rupture, gastrectomy(stomach cancer).
