• Breast cancer is one of the most common malignancies in women worldwide. Therefore, it is very important to investigate biological features of breast carcinoma in order to improve clinical outcome of the patients. It is well known that estrogens play important roles in the development of human breast carcinomas, and endocrine therapies are frequently used in these patients to block the intratumoral estrogen actions. In the Division of Pathology and Histotechnology, we analyze hormone actions in breast carcinoma by pathological methods as well as various molecular biological techniques.

It will be possible to newly develop diagnostic techniques regarding prediction of prognosis and/or effectiveness of treatment in breast cancer patients.
