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 biopsy is a procedure in which small hollow needle-core samples are removed from a man's prostate gland to be examined for the presence of prostate cancer.It is typically performed when the result from a PSA blood test is high. [1]
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.
A biopsy or MRI may be recommended when you have an elevated PSA or if a PSE test shows a result of “high likelihood for prostate cancer,” Dr. Pohlman says.
“Because of screening and testing, it has a high cure rate once caught early.” ... PSA levels between 4 and 10 suggest you could have about a 25 percent chance of prostate cancer, and levels ...
Molecular analysis has shown that high grade PIN and prostate cancer share many genetic abnormalities. [5] The risk for men with high grade PIN of being diagnosed with prostate cancer after repeat biopsy has decreased since the introduction of biopsies at more than six locations (traditional sextant biopsies). [3]
An MRI did not reveal anything and a second PSA test remained high. A biopsy was ordered and in March it revealed early stage cancer. ... Wojnarowski learned of the news just before doing a hit on ...

Those with high levels of PSA in their blood are at increased risk for developing prostate cancer. Diagnosis requires a biopsy of the prostate.
