Chemoprevention of cancer is a new branch of the medical science and represents a topic of increasing concern in public health. Over the last decade chemoprevention has been extensively studied from many points of view, and topics in the field of chemoprevention have expanded considerably. Breast cancer, the most common malignant neoplasm in women, is one of the areas of clinical interest for chemoprevention. In this paper the authors synthesized the "status of art" in chemoprevention of breast cancer with retinoids and antiestrogens.
