10 years ago I had 350 cc silicone implants put it. My breasts had gone from an a/b to a DDD while breast feeding so there was a lot of extra skin. My right implant had ruptured, and therefore I am getting my implants replaced. Originally then I had my first implants I was 110 lbs 5'5", now I am about 135 lbs. I am torn between 450 cc & 500 cc high definition, is there a noticeable difference? I will be also having a tummy tuck
