MAGE A4 Tesring : The mage a4 antigen, even though it was named the melanoma associated antigen, is a non-specific antigen that has been linked to a wide variety of tumors. It's efficacy is still being debated as a stand alone predictor. Your physician should investigate and rule out the most likely malignancies for your age and family history, including early breast and oral cancer, as well as others less likely.

Canbe false positive: Too new of a test to talk about positive predictive value- would recommend f/u with md for rpt scans in 3-6 mths to ensure stability.
