5. Study Description
Brief Summary
The aim of this study is to define silent breast cancer prevalence in both sexes and will be held by biopsies performed in imaging suspicious areas of the breast (ecography and mammography) in cadavers without known breast cancer.
Detailed Description
Cadavers of both sexes are going to be submitted to bilateral mastectomy. The specimens are going to be examined by palpation, ecography and mammography and all areas with (Breast Imaging Reporting and Data System) BI-RADS classification >= 3 are going to be biopsied.
Biopsy specimens are going to be processed by the pathology department and cancers are going to be identified and classified by their molecular type.
The investigators intend to know which is the disease reservoir in various ages.
