Ron,
It is wise not to rush or be rushed into a decision: best to gather your thoughts, don't panic and think things through logically.
You'll hear a lot of technical views, and from many who can only think of one treatment option. One size does not fit all, and treatment choices depend on the diagnosis and preference.
I'll try to give you a few down to earth tips without going into a lot of detail right now.
Although you have a number of positive cores, most are gleason 6 scores which are in the low to medium risk category, More agressive higher risk scores are 8 and above, which need more urgent and agressive treatment.
* Firstly, gleason readings are subjective, (it depends on who looks at the samples) so it's important to obtain a 2nd reading of your slides, as your treatment considerations are based on those numbers.
* THE most important aspect is to select the best available doctor regardless of what treatment is chosen: eg, the doctor is more critical than whether open or robotic surgery is used.
* Despite what some might suggest, most of the mainstream treatments provide similar long term results, so it often comes down to personal preference and consideration of the potential side effects.
There's plenty of information on the various choices available: don't hesitate to post again with any questions which come to mind.
Best Wishes,
John
