hi there is no absolutely right or wrong reading for psa. the level can be raised in several conditions other than prostate cancer. the reading also tends to rise as men get older. if your psa is only slightly raised you may have an enlarged prostate but not cancer. your doctor is likely to ask you if you have any symptoms that might indicate a possible prostate cancer. these include problems passing urine weight loss low back pain blood in the urine and problems getting an erection (impotence). a psa level that is high for a person's age means a doctor should make an urgent referral to a specialist for further investigations. these include a transrectal ultrasound and a needle biopsy of the prostate. a biopsy means taking a small sample of tissue to examine. this is the only sure way to diagnose prostate cancer. if cancer cells are seen in the biopsy sample when it is looked at under a microscope there is proof of cancer. strictly speaking if no cancer cells are found your doctor couldn't be certain there were no cancer cells in the whole prostate. a specialist in prostate diseases (a urologist) has to take the results of all the tests together to make a diagnosis or rule cancer out. i do hope t5his helps you. good luck
is a psa of 19 with fever a sign of cancer or just prostate infection
