The Breast Unit was established in 2004 inside the National Center of Oncology in Armenia due to a more-than-10-year-long multidisciplinary approach to breast cancer diagnosis and treatment. Our department of breast diseases has 60 beds. Every year Armenia comes up with already more than 1000 cases of breast cancer, more than half of which are engaged in our department. We use protocols and clinical recommendations from NCCN, ESMO, ASCO, EUSOMA. We offer a coordinated approach provided by a team of experts in all fields involved in breast diseases, including all steps from risk assessment to long term follow up. The multidisciplinary team, made up of oncologists, radiologists, radiation oncologists, pathologists and surgeons, meets every two weeks for patient's evaluation and the definition of diagnostic and therapeutic strategies. The breast unit provides care for all stages of BC: neo- and adjuvant chemotherapy, oncoplastic and conserving surgery, breast reconstruction, treatment of locally advanced and metastatic BC, rehabilitative and psychological support. Our strategy is to tailor individualized treatment according to clinical stage and tumour biology.
