The prostate's primary function is to produce the fluid that nourishes and transports sperm (seminal fluid). The PSA test is a blood test used primarily to screen for prostate cancer. The test measures the amount of prostate-specific antigen (PSA) in your blood.
PSA levels can be detected in the blood, urine, or semen. Blood PSA testing is used as a screening test for prostate cancer. Prostate-specific antigen (PSA) levels by age remain the same across most populations. A PSA level above 4.0 ng/mL in any age group must be investigated.
A PSA test is a blood test used primarily to screen for elevated levels of the prostate specific antigen (PSA) released by the prostate. It can be elevated for a variety of reasons. PSA screening continues to be a highly debated, controversial topic among the medical community.
Tests should be done every six (6) months to measure the changes in PSA levels. The next step would include an MRI or other to reveal any lesions or other within the prostate gland. If so, then normally a biopsy is done to validate Yes or no. Read, and research to be able to ask the right questions.
Generally speaking, though, PSA levels for men who are: Age 60 or older: should be at or below 4.0 mg/mL; Age 59 or younger: should be at or below 2.5 mg/mL; The average PSA for men in the younger group is <1.0 mg/mL. Why are my PSA levels elevated? Your PSA levels could be elevated for many reasons.
The most common scale used to evaluate the grade of prostate cancer cells is called a Gleason score. Gleason scoring combines two numbers and can range from 2 (nonaggressive cancer) to 10 (very aggressive cancer), though the lower part of the range isn't used as often.
