Invasive Carcinoma of the Breast of the Nonspecific Type about 3 Cases

Breast cancer is the leading cancer in women worldwide, and the leading cause of cancer-related death in women. Invasive cancer accounts for over 90% of all histological types. The most common breast cancer (95%) is adenocarcinoma, which develops from the epithelial cells of the mammary gland. Infiltrating or invasive carcinoma includes the common infiltrating ductal carcinoma (IDC) (81%), IDC with a predominantly intraductal component (4%), infiltrating lobular carcinoma (10%), usually bilateral, and even rarer forms. Non-specific infiltrating carcinoma is the most common histological type of breast cancer, accounting for around 80% of all cancers, and its clinical and radiological presentation differs according to grade of differentiation. We report three cases of invasive breast carcinoma of the nonspecific type whose diagnosis was suspected by mammography and breast ultrasound and confirmed by anatomopathology of the three breast nodule biopsies and surgical specimens. All three patients were treated surgically by total mastectomy with homolateral axillary lymph node dissection and adjuvant chemotherapy and radiotherapy after a multidisciplinary coordination meeting.
