I just had my annual blood screening yesterday and chose not to have the PSA. I went to the site provided by one of the posters here, the American Cancer Society, and followed their advice, which said that with a 2.5 or lower PSA screening is not needed every years. since last year I had a 1.5, I elected not to have the test this year. It seems to met that the American Cancer society is as good as any organization on advice about cancer screening. I am almost 64 and do not want to get involved in medical procedures that lead to more and more unless I absolutely have to. So it looks like previous PSA values should also play a role in the decision of getting or not getting a PSA every year.
