In medicine, prostate specific antigen (PSA) is a "glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer."[1]

Abnormal PSA results may revert to normal, although the meaning of this reversion is not clear.[2][3]
