What is PSA? PSA is one of three major factors that are considered when evaluating a manâs particular case of prostate cancer. PSA stands for Prostate Specific Antigen. The word âspecificâ means that this enzyme is produced only by prostate cellsâwhether normal prostate cells or prostate cancer cells. No other cells (lung, intestine, liver, etc.) make PSA. The purpose of PSA is to keep semen (the white substance ejaculated during sexual intercourse) liquefied.
