Can you get cancer if you lipo your fat from your stomach, sides,& back to your breasts and butt? What are the cons?

Fat Transfer to my butt and Breasts. I am 5'5 1/2 weighing about 140-145 pounds. I am thinking about getting lipo from my sides, back, and stomach to put into my butt and breasts. But I was told that if you put it in your breast it would cause cancer? true? Would this be a healthier way or breast implants?
