PSA stands for two main things depending on the context:
- Public Service Announcement : An announcement made on TV, radio, or the internet intended to give the public an important message, often about health, safety, or social issues
- Prostate-Specific Antigen : A protein produced by the prostate gland, measurable in the blood. Elevated PSA levels can indicate prostate cancer or other prostate conditions like benign prostatic hyperplasia or prostatitis. The PSA test is commonly used to screen for or monitor prostate health
