Good advice but as I was told after my blood tests the PSA test can give in certain circumstances a false negative or positive so it is best to have an internal examination as well for greater clarity. I only say this because I'm sure many are put off by the thought of the internal exam. Don't be, I had my PSA level checked last month which was fine but I was recommended to have the internal exam, it is not as bad as you would imagine , I didn't find it painful at all . Put aside any feelings of embarrassment you may have, the test is quick and over before you know it. I second Jaco's sentiment above, you really do owe it yourselves.
To you Jaco I'm sure your positive attitude has helped you through some tough times and kudos to you for getting on with your life . Hopefully your post will encourage more people to get checked out.
