Good info, good topic. Affects all of us old codgers one way or another. I could write a book on Prostate, I know it backwards and forwards, inside and out. All of what my old friend JohnM says is true. Also, no two people's situation is the same, our Prostate situations are as varied as the size of our .... Prostates.
My situation evolved like this. While still working 7 years ago, I decided to have a physical and had not had one for 4 years. The GP did all the tests, all came out good. But doing the finger wave, he said my Prostate was "slightly enlarged", probably normal for "your age". My PSA was about 3.3. He said to come back in 3 months and they would do another PSA for free. He lied because the lab still charged for the test.
Anyway, it came up slightly, to about 3.5. He said I should see a Urologist and scheduled me an appointment. Remember, a GP might do 5 - 10 finger waves a day. A Urologist does 100.
At the Urologist, he did one finger wave and said I had "something" there. Scheduled biopsy. Bingo. Caught it in the early stage, supposedly. In scheduling the operation, it took a few weeks, then the doctors went on vacation skiiing for a week. It was probably two months after my first exam before the operation took place. In the meantime, underwent a "bone scan". I was able to watch it on the little screen as it scanned my body. Showed the white spot down there. Showed white spots on top of my shoulders where arthritis was, from years of playing fast pitch softball. Also showed white tips of my toes where the old nurse didn't have me take off my steel toe boots. I wondered if she really knew what she was doing.
Here's the kicker. At the hospital after the operation, PSA was then about 3.7, doctor came out and told wife that I was lucky, it actually was starting to "break out" of the Prostate. Said that if I had waited 6 more months .....curtains. Well NO SHEITE. All the stalling around. Turns out I still had a slight number so had to undergo some radiation. Talking to a guy there one day, a younger guy in his early 50's, he said he was going to work in Iraq and at a physical his PSA was 11.0. So this ties in with what JohnM said. It does vary greatly with age.
It's been seven years and PSA has been fine, 0.0. Once a year, I make sure it's tested. But I cut nearly all beef out of my diet. For about 3 years before my diagnosis, I had been eating Hamburgers and Fries EVERY day. Now, it's only Chicken or Turkey Burgers.
Go ahead, call me a Wuss.
What you can carry is all you need for an emergency situation. The rest you can pick up off the dead and dying if it gets that bad.
