After surgery or radiation therapy, PSA may start to rise again, which is called biochemical recurrence if a certain threshold is met in PSA levels (typically 0.1 or 0.2 ng/ml for surgery). At 10 years of follow-up after surgery, there is an overall risk of biochemical recurrence of 30–50%, depending on the initial risk state, and salvage ...
A PSA is like any routine blood test, Dr. Feng says. But you should refrain from ejaculating for at least 48 hours before the exam. This could temporarily raise your PSA levels, which might ...
It may also be considered advisable after a digital rectal exam (DRE) finds possible abnormality. PSA screening is controversial as PSA may become elevated due to non-cancerous conditions such as benign prostatic hyperplasia (BPH), by infection, or by manipulation of the prostate during surgery or catheterization. Additionally many prostate ...
Prostate-specific antigen. Prostate-specific antigen (PSA) is secreted by the epithelial cells of the prostate gland and can be detected in a sample of blood. [14] PSA is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer or other prostate disorders. [15]

Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), P-30 antigen, is a glycoprotein enzyme encoded in humans by the KLK3 gene.PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland in men and the paraurethral glands in women.
Prostate cancer is the uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder.Abnormal growth of prostate tissue is usually detected through screening tests, typically blood tests that check for prostate-specific antigen (PSA) levels.
Biochemical recurrence is a rise in the blood level of prostate-specific antigen (PSA) in prostate cancer patients after treatment with surgery or radiation. Biochemical recurrence may occur in patients who do not have symptoms. It may mean that the cancer has come back. Also called PSA failure and biochemical relapse. [1]
