                        When levels of prostate specific antigen [PSA] begin to rise, the general meaning is that antibodies are increased to fight some kind of irritation or disease.  The existence of a tumor, benign or otherwise, is a common reason for a rise in the PSA or antibody level.  A 'normal' PSA reading is between ) and 4.0.  When that reading begins to rise over 4, you doctor will likely express concern and often suggest a biopsy of parts of the prostate.  When my PSA became elevated, a biopsy was performed.  It showed nothing [not unusual].  However, when retested 6 months later, a malignant tumor was discovered.  Once diagnosed, the treatment options are several, including doing nothing.  Because of the size of my particular tumor plus an estimate of its aggressiveness [called the Gleason Rating], I elected for radioactive seed implantation.  This was 2 years ago.  My PSA, which was slightly above 6 at the time of the implantation, dropped to zero and has stayed there.  Before deciding what you want to do about your rising PSA, you should definitely get another opinion.
