The program is an outgrowth of the 1986 National Childhood Vaccine Injury Act (NCVIA), which requires health care providers to report: Any event listed by the vaccine manufacturer as a contraindication to subsequent doses of the vaccine.
1 Men in the range of 60 to 69 years have normal PSA levels that are less than 4.5 ng/mL. 2  Men over the age of 70 years have normal PSA levels that are less than 6.5 ng/mL. 3  It is also important to note that the normal ranges of PSA results may vary from one laboratory to another.
Most men without prostate cancer have PSA levels under 4 nanograms per milliliter (ng/mL) of blood. The chance of having prostate cancer goes up as the PSA level goes up. When prostate cancer develops, the PSA level usually goes above 4. Still, a level below 4 does not guarantee that a man doesnât have cancer. About 15% of men with a PSA below 4 will have prostate cancer on a biopsy.
