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.
PSA levels between 4 and 10 suggest you could have about a 25 percent chance of prostate cancer, and levels over 10 signal that your chance of having the cancer is more than 50 percent.
The American Urological Association recommends that you get a baseline PSA test between ages 45 and 50, but screening can start at age 40 for those at a higher risk for prostate cancer, such as ...
Men with high PSA levels are often recommended to repeat the blood test four to six weeks later, as PSA levels can fluctuate unrelated to prostate cancer. [17] Benign prostatic hyperplasia, prostate infection, recent ejaculation, and some urological procedures can increase PSA levels; taking 5α-reductase inhibitors can decrease PSA levels. [15]
A digital rectal examination and the measurement of a prostate-specific antigen (PSA) level are usually the first investigations done to check for prostate cancer. PSA values are difficult to interpret, because a high value might be present in a person without cancer, and a low value can be present in someone with cancer. [28]
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 ...
