Prostataspezifisches

Prostataspezifisches Antigen, commonly known as PSA, is a protein produced by the cells of the prostate gland in men. It is manufactured by both normal prostate cells and cancer cells. PSA is normally secreted into the seminal fluid, but a small amount also enters the bloodstream.

Measuring PSA levels in the blood is a common practice, often used as a screening tool for prostate cancer. An elevated PSA level can indicate the presence of prostate cancer, but it can also be caused by other non-cancerous conditions affecting the prostate, such as benign prostatic hyperplasia (BPH), inflammation of the prostate (prostatitis), or recent ejaculation.

The interpretation of PSA levels is complex and should always be done in the context of a man's overall health, age, and other medical factors. Doctors consider PSA levels in conjunction with other diagnostic tests, such as a digital rectal examination (DRE), and sometimes further investigations like a prostate biopsy, to make a diagnosis. It is important to note that PSA screening guidelines and recommendations can vary among different medical organizations.
