Not always...: While a high psa score may be secondary to prostate carcinoma, other things can also cause elevated psa, such as inflammation or "prostatitis". It is important to correlate the degree of elevation to the clinical setting for the patient involved, and it may also be important to follow the psa level over time.

Not always: Usually the change in a psa value from one to the next is more concerning than the sole value itself. Rate of change is important too. Psa is a tool that helps us determine who is at highest risk for prostate cancer and therefore who needs a biopsy to diagnose cancer. Normal values slowly increase as one ages. However psa values over 20ng/ml are very concerning for cancer and need a biopsy.
