As I said in my post on your previous thread, I also was 10-12 core positive and they thought it was Gleason 6. I went straight for surgery.
You may have your biopsy slides sent for a second opinion, I didn't.
Two heads are better than one, as they say.
After my surgery, the pathology upgraded by Gleason to 3+4=7 and the tumor was 50% involved in the prostate. Some of the tumor was beginning to leave the capsule (prostate). I don't think I would have changed my mine but this is a life changing decision. Your sex life and continence issues will be affected for sometime if not forever.
The more you know before making your treatment the better.
I was born in South Carolina, by the way. Don't be afraid to travel to get the best treatment. My surgeon had done over 5,000 surgeries when I had mine 3 years ago this month. Currently he is at over 8,000 completed surgeries. Lucky for me he was in Orlando, 3 hours away.
