   Diagnosis involves ruling out breast cancer. [1] Fibrocystic changes include fibroadenomas, fibrosis, papillomas of the breast, [1] and apocrine-type metaplasia. [4] Management may involve education about the condition, using a well fitting bra, and pain medication, if needed. [1] Occasionally danazol or tamoxifen may be used for pain. [1]

   These classifications are spindle cell, squamous cells, matrix-producing, carcinosarcoma, and MBC with osteoclastic giant cell. Another research group, Oberman et al., proposed a classification system consisting of spindle cell carcinoma, invasive ductal carcinoma with extensive squamous metaplasia, and invasive ductal carcinoma with ...
