@Cafrini60 I was wondering if you've joined the Breast Reconstruction Group if not here's the link
https://onlinenetwork.bcna.org.au/group/1-choosing-breast-reconstructionI think there would be some help with experience in the Group. I didn't have fat grafting but rather they did liposuction of the hips and torso as part of the Diep Flap reconstruction.
I'm sure theres more experience in the group and highly recommend you popping over, plus it's a private Group and the Forum is public. Hugs M x
