Sounds like you're doing all the right things with research and asking questions, especially questioning your doctors.
Support groups are great sources of information as well. Prostate cancer survivors can often give you more real world info than many doctors.
I was diagnosed with prostate cancer 9 years ago, at age 51. Biopsy showed extensive cancer and the Gleason score was 6.
Due to the relatively poor pathology, I opted for a radical prostatectomy. That was followed by 35 sessions of radiation therapy.
The Da Vinci method was just approved by the FDA in 2000, the same month I had my surgery. I didn't even hear of it until a few years later.
The standard surgical method for a radical was a very difficult surgery. I was in the hospital for several days and was out of work for two months.
As mentioned by another forum member, it's crucial that you have a highly skilled surgeon. That applies to the DaVinci Robot method as well as the older method. I'd look for references and ask lots of questions, especially, how many of these operations has the surgeon done. Don't be bashful. It's your life. You definitely want only the best. A highly skilled surgeon can save you lots and lots of problems down the road. There are an incredible number of horror stories out there, problems and issues that could have been avoided by a more skilled surgeon.
For me, I was diagnosed a little to soon, I guess. If I had my choices, I'd go with the DaVinci Robotic surgery. Much faster recovery time, far less invasive. I've talked with several prostate cancer survivors who had robotic surgery and also know many men who had the prostate removed using the older, standard surgery. I've never spoken to anyone who had robotic surgery who wished they had the other type of surgery. Every single man I know who had the older surgery wishes the robotic method, at least had been an option for them.
I can't comment on seed implants or other methods. These were not an option for me and my research was very superficial. I know men who had seed implants which were successful. Unfortunately, I also know men for whom it was probably not the best choice.
For me, so far so good. I had a relatively long recovery time, which was typical for my type of surgery and had few long lasting problems from the surgery. I was very fortunate.
It's a scary time, indeed, and sometimes you're overwhelmed with information.
Prior to my surgery, I made friends with a fellow who had recently been through the same thing. When I had questions I often called him, before and after the operation. I found his real world advice extremely valuable. There's something about the voice of experience that can't be replaced. I've made it a point to try to help anyone going down that road. If you'd like to P.M. me, I'd be happy to answer any questions that I can. If you like, I'll give you my phone number and you can call me anytime.
Good luck and keep doing the things you're doing.
