ABSTRACT:
The present invention is directed to compositions regarding a specific mutation in estrogen receptor alpha and their use as diagnostic markers in breast tissue, such as premalignant lesions, for the development of breast cancer. More specifically, cells of breast cancer whose nucleic acid comprises the estrogen receptor alpha mutation identify the breast cancer to be an invasive breast cancer.
