PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland.

PSA Test (introduced in '86) measures PSA in man blood.

This test has the ability to detect cancer in men prostate earlier comparing with digital rectal exam.

The risk of cancer based on PSA levels follows:

PSA levels under 4 ng/mL: "normal"
4 to 10 ng/mL: 20 to 30% risk
10 to 20 ng/mL: 50 to 75% risk
Above 20 ng/mL: 90%.

BUT one of the very imporant things here is that there are OTHER factors which can raise PSA levels and these are:
- prostatitis (inflammation)
- benign prostatic hypertrophy(condition in which an overgrowth of prostate tissue pushes against the urethra and the bladder, blocking the flow of urine)
- Urinary Tract Infection

The best way to avoid this is to maintain good prostate and overall health based on the following guidelines:

Eat more fruits, vegetables and nuts.
Add some pomegranate to your diet.
Exercise more.
Lose weight.
Eat more tomatoes. ...
Reduce animal protein intake.
Try quercetin and pollen


*Most men with an elevated PSA level turn out not to have prostate cancer; only about 25% of men who have a prostate biopsy due to an elevated PSA level actually are found to have prostate cancer when a biopsy is done.[1]
