An increase in protein-specific antigen (PSA) levels may be associated with many medical conditions that can affectthe prostate gland, such ascancer, benign prostatic hyperplasia, prostatitis and an infection. Another factor that alsomay raise the PSA level is the aging process, relates MedicineNet. PSAis a protein that the prostate gland manufactures.
The normal range for PSA levels is between 1.0 to 4.0 ng/mL, according to MedicineNet. Men with prostate cancer tend tohave levels of PSA that are significantlyhigher than 4.0 ng/mL. A PSAblood testmay be used to screen men for prostate cancer. However, other tests like a biopsy may also be necessary to diagnose if it is cancer becausehaving a high PSA levelcan also be caused by an inflammation or infection of the prostate gland. Similarly, there is a possibility that men with low PSA levels can also have prostate cancer.
Based on guidelines from the American Urological Association (AUA), PSA screening is recommended for men between the ages of 55 to 69, according to Mayo Clinic. The benefit of a PSAtest is that if a man has prostate cancer it may be caught in its early stages and treated. The test is also important because prostate cancer can progress at a slow rate and cause no symptoms.
