- QUESTION: During a recent office visit to my doctor, he took a number of
- blood tests, though I had no complaints other than a bad cold. I must now
- visit again, for one of the tests, a prostate test, has been found to be
- abnormal. Still, his nurse assured me that it may not be anything to worry
- about. Would you please tell me what is going on? I am losing sleep, just
- worrying about what might be in store for me.

- ANSWER: It is most probable that the test in question is a new screening
- tool, the "prostate-specific antigen" (PSA), which is recommended as part of
- the evaluation for men over the age of 50. It tests for a specific chemical
- (antigen) which is produced by the cells of the prostate. When the results
- show elevated amounts of this substance, it MAY indicate the presence of
- cancer cells, which produce large quantities of the antigen. However, since
- the same antigen is produced by normal cells, a man with an enlarged prostate
- due to benign enlargement (hypertrophy) may also be found to have an elevated
- test finding. That is the basis for the nurse's comments that you may not
- have anything to worry about.
- When this test is used appropriately as a screening tool, an elevated
- finding requires additional testing to determine if a cancer is really
- present. In addition to a digital rectal examination, an ultrasound test or
- a biopsy can be used to fully evaluate the situation and make a correct
- diagnosis. So a return visit to the doctor's office is in order, as is
- additional investigation.
- While the test is not as specific as we all would like, and a false
- negative can cause worry and loss of sleep, an early diagnosis is so important
- in fighting cancer of the prostate that we can rationalize the use of this
- test as a general screening procedure in middle aged men. Only when prostate
- cancer is detected at its early stages, before it has had a chance to spread
- to other parts of the body, can the surgical removal of the diseased gland
- provide the desired cure. Take heart and follow through, for ultimately that
- is the best course to take to obtain the best results.
