[Etiopathogenetic, diagnostic and clinical considerations on simultaneous bilateral carcinomas of the breast. II]

In the first note the Authors have described five cases of bilateral simultaneous breast carcinoma. Now they shortly describe some opinions about the problems of the genetic independence between the two diseases. They draw attention about the histologic diagnosis and the identification of diseases underestimated and now explained as carcinoma "in situ" potentially fit for transformation in infiltrating cancer. For this reason it's important and justifiable to have the patients with cancer of the breast, a series of clinical research as well as mammography thermography and biopsy of controlateral breast in order to ascertain the presence of carcinoma "in situ" that could justify the prophylactic mastectomy.
