I went back for partial excision of necrotic fat and more fat graft to make the areas less lumpy. Now my doctor has asked me to apply ultrasound massage to breasts. Question will that disrupt the fat graft or kill the fat?

This question should be addressed to your surgeon so, then can explain their plan of action. Yes, massage & ultrasound can disrupt fat grafting. However, ultrasound and massage may also assist in the resolution of your fat necrosis. Best,
