PSA changed (high) can be a symptom of any disease or problem in the prostate, such as cancer, infection, benign hypertrophy (growth), or trauma to it. Age is also a factor that contributes to the increased rate of PSA in the blood.
Typically, a PSA above 4.0 ng / ml could mean prostate cancer, although this is not enough to detect the disease. In this case, the patient should be submitted to rectal examination and ultrasonography. Depending on the result, a prostate biopsy may still be necessary.
In fact, about 17% of men with prostate cancer do not present altered PSA, so rectal touch.
PSA (Prostate Specific Antigen) is a substance produced by the prostate that circulates normally through the bloodstream. Changes in the prostate cause an increase in the release of PSA into the blood through the vessels and lymphatic tissues that cross the prostate.
PSA examination associated with rectal examination is the most effective way to diagnose prostate cancer early.
