I was diagnosed with PASH (Pseudoangiomatous Stromal Hyperplasia) - is it safe to have a Breast Lift with fat grafting? (photo)

I've always been petite, 5"4, 118 pounds with a DD chest. After breastfeeding two babies my DD cup size literally disappeared to a sad C/B cup. Not a lot of excess skin, its like my chest evaporated. I was diagnosed with PASH after I stopped breastfeeding my first child. The idea of mixing implants with my already problematic breasts doesn't seem like the ideal choice for me. I've always exercised and before children never lost breast volume, so hoping a fat graft could be a viable option.
