My father who is going to be 85 in August was diagnosed with prostate cancer about 8 years ago. He was having regular check-ups including PSA tests for years. The doctor had noticed an elevated level in the PSA test which resulted in a round of radiation treatments (36 total). Fortunately he is a very healthy individual and hasn't had any further issues. I have had PSA tests done in the past however my doctor just recently stated that he doesn't think that it is necessary to carry on with the PSA testing.
