Preventative bilateral mastectomy

Hi there, 

1. This year I made the decision to send off my family history notes to Womens Health to look into my risk at developing C in later years. 
   It came back as high risk, and I was recommended getting yearly mammograms from the age of 40. 
   However, the breast consultant at my local Hospital called me into their clinic, I assume after reading my records. So it turns out that I can have a bilateral mastectomy and prevent my chances by up to 90%. I was a bit shocked initially but having thought about it now for a week, it’s something I just need to do. I have a young family, this is important, despite the fear of surgery and recovery. I would also reduce the daily struggle of anxiety. 
   However, the waiting list is well over 3 years. Now I know I am at risk I am wanting to explore all my options. One of which is, could I address this earlier? Can I go down the private route? What are the costs? What clinic? What consultant? 
   I just don’t know where to start, I don’t know anyone having gone through this before… any advice would be much appreciated. Thank you
