Reduction and gigantomastia

Hi all, 

I am brand new here. To make a long story short... My chest has grown a ton over the last few years (from a 36DDD to well over a 38O). My primary care doctor believes I have gigantomastia due to a hormonal imbalance but I need to be officially diagnosed. Anyway ..I'm wondering what to do in terms of a reduction :( if anyone has advice to share that'd be great. 

Thank you in advance
