First, a bbl performed in the evidence based best way, has a zero mortality rate. The last five years of research has shown us why fat emboli occur: disruption of the gluteus maximus muscle fascia.

Second, contrary to 'dr old school', his fears should have been extinguished in 2006, when the data showed that fat grafting to the breast on average created no different calcification patterns as other breast surgeries, and that those calcifications were far different than microcalcifications of cancer.

Go to a few true experts to get real answers.
