This forum is for the discussion of anything to do with Prostate Cancer. There are only four rules:
No fundraisers, no commercials (although it is OK to recommend choices of treatment or medical people based on your personal research; invitations to participate in third-party surveys are also acceptable, provided there is no compensation to YANA);
No harvesting e-mail addresses for Spam;
No insults or flaming - be polite and respectful at all times and understand that there may be a variety of points of view, all of which may have some validity;
Opinions are OK, but please provide as much factual evidence as possible for any assertions that you are making
Failure to abide by these simple rules will result in the immediate and permanent suspension of your posting privileges.

Please try to understand that these posts are read by a lot of intelligent people, from many different backgrounds. They are looking/hoping for the truth and any posts that get carried away a bit with detailed info which may or may not match what they have read before is going to be torn apart, nit by nit until the truth (or best we can do) is laid out before us.
That said, my profession is ... woups ... was radiation physics. I remember a lot, also have forgotten alot, cus I don't use it any more. Particle physics is not precise. Most of the energy is delivered where you want it, but a surprising amount goes elsewhere...like from the beam transmitter device to the target and even beyond the target. You are talking about probabilities, as to where the energy is deposited. Any cell that happens to be in the path of a photon will be destroyed, whether it is in the target, before the target or after the target. Company Reps selling PT pick a small part of the truth and blow it way out of proportion to sell their product. I've gone around with several men who think that GOD created PT and it is good for everyone ..... period. I can't (don't care ither) change their minds and I've sorta stopped trying (Really Joe, then what is all this gobbly-gook you've written?).
Si Joe, probabilities, we agree! And yes God did develop protons, X-rays, and all that other stuff, assuming you believe in God. I would say he's a singularity.
One thing we do know. The known safe dose of ionizing radiation is 0.00000000000000000000.... so please give me less of it. I'll take the low probability of a tiny Proton's stray energy any day over the known by physics near 100% probability of X-Ray radiation stray energy, most energy goes where it is not wanted.
So, a recovering physicist eh? I like that I hope you have a ponytail while surfing in an exotic place. I keep trying to leave this engineer biz but find there are no jobs for ex-engineers so I keep going back, one more time, each time.
