What are the PSA levels and what do they mean?

PSA stands for prostate specific antigen. It is a sensitive indicator for presence or absence of prostate cancer. (However, there can be false positives and false negatives.)

PSA cut-offs are set around 4.0. However, it is the rate of rise that should be paid close attention to. If three consecutive rises in the PSA occur, your physician should recommend further testing, including DRE (digital rectal exam) and possibly rectal ultrasound (with or without ultrasound guided biopsy of the prostate gland.

Consult your physician for further details, in your particular circumstance.
