Hi,
I had a radical four years ago. My PSA went from 4.1 to 6.6 in eighteen months. Dre. found nothing.
I was 61, had a biopsy and five out of the eight samples were positive.
On the pathology reports......ie blood test results, it states that 20% of men in Canada have PCa in the normal range of their PSA results.
Most of the guys I know that have PCa, and in a couple of articles I've read........most agree that ejaculation does cause PSA to rise. In fact a Dre. exam will cause your PSA to rise.
Hope I've been some help.
Good luck..............Stan.
