Hyperadenia- Extra breast tissue extending up into the axilla region (tail of Spence)

I Have a strange problem that only really became a problem when I hit puberty and had to start wearing bras. I have extra breast tissue in my underarm area that gets larger and swollen and sore when I’m coming up to mestruation. It hurts so much some months that I can’t wear a bra- which is hard as my breast swell and get sore also and so I need a bra for support during this time. 
 
Will Medicare help fund the removal of this tissue? Can you suggest a surgeon in WA who would be a good option for this procedure?
