The PSA4 detected Donald's cancer early, and Dave Fleisner saved his father's life with the product he helped create. The PSA4 blood test is a laboratory procedure that measures a substance produced by the prostate gland called Prostate Specific Antigen. Small amounts of this substance may get into the bloodstream and can be measured by the PSA test. If results of the test show a number four or higher, patients are recommended to seek further testing.
Prostate cancer is the most common cancer found in men in the United States.
It occurs in about 1 out of 10 men during their lifetime. Prostate cancer is more common in older men and is the second leading cause of cancer death in American men. Certain conditions of the prostate may raise the level of PSA in the blood. High levels of PSA do not harm you, but they are an important signal of possible prostate disease.
