I'm getting my second BA in two weeks. Initially, I wanted a bigger implant, but my surgeon wouldn't do it because there were too many risks. I am currently 375 cc, HP, silicone. I will be getting 550 HP silicone implants. I'm nervous that this will not give me more projection. I know every body is different.. Generally speaking..... Will this be a big enough increase to go up in a cup size. Again, this is how big my surgeon will go.
