Diagnostic Utility

Mammaglobin is a 10 kDa glycoprotein of unknown function. It is found in a sustantial proportion of primary and metastatic breast carcinoma. It is also expressed in sweat gland tumors and a subset of salivary gland neoplasms. When combined with other breast markers, such as GCDFP-15, a much higher sensitivity (reported to be in the 80% range) for breast carcinoma may be achieved.
