Hi there- I agree that the risks of a Brazilian Butt Lift are generally those of liposuction (because liposuction is 1/2 of the operation), with the additional risks of fat necrosis (formation of lumps in the buttocks). All in all, however, the procedure should carry a very favorable risk to benefit ratio when performed by a qualified and experienced surgeon. Make sure you find a Board Certified Plastic Surgeon and he/she has experience performing the procedure you are interested in, as well as any procedures that may be necessary if results aren't excellent.
