Hi, 

I had a partial mastectomy with a latissimus dorsi flap, which is where they take a flap of tissue/muscle from your back area. I only had small boobs - 34B. They did this as they had to take a large area away and it would leave me very lop sided. Now - 2 years down the line, my new reconstructed boob is an odd shape and smaller. I suppose with your reconstruction - if they used your own tissue, it depends how much they can take. Implant wise - have they said you will need radiotherapy? I know that often implants are done after radio as it can cause issues and to be honest - it isn't like having reconstruction for cosmestic reasons so they aren't going to endeavour to make them the same. But if you are concerned, I would ask your surgeon why this is the case.

Good luck x
