Don, I'm a nine year+ survivor. My biopsy showed fairly significant involvement, and I decided to go for surgical removal. At that time, Dr. Walsh at Johns Hopkins had written the book on techniques for removal that did the least damage to the surrounding nerves, so I had the surgery done by a member of his team. I looked at the radiation, and seed plant, options but thought total removal via surgery had the most promise for long term survival. At the present, my PSA readings are too low to measure, so I believe the cancer is not there.
The down side is the inevitable erectile problems, but there are chemicals to help with that.
I wish you the best, and would suggest you get the best possible quality treatment no matter where you might have to go for it. Should you decide to come north to Hopkins, we'd be happy to provide whatever support & accommodations you need.
ps:you'll find that after dropping your drawers a few dozen times so "another" medical professional can check your prostrate, all pretenses of modesty are history.
