What is prostate PSA?

Prostate specific antigen (PSA) is a prostate specific antigen (PSA) that is a tumor marker for prostate cancer and can assist in the diagnosis of prostate cancer. PSA

is a single-chain glycoprotein secreted by the prostate and is specific to prostate tissue. When PSA is elevated, it can indicate the possibility of prostate cancer, but it cannot be diagnosed clearly because there are many factors affecting PSA, such as catheter stimulation, inflammation and prostate hyperplasia.

It is recommended that patients with abnormally elevated PSA should seek medical attention for further examination, identify specific causes, and cooperate with treatment.
