Your question highlights the confusion and frutration most women feel when trying to reconcile breast implant volume (in cc's), profile (LP, MP, MP+ and High Profile), location of implant placememt (under VS. Over the pectoralis Major muscle)with the only description they know for breast sizing - bra cup sizes.
Unfortunately, there is NO industry wide bra cup standard and a C in one bra is NOT a C in another manufacturer's bra. To add to the confusion, since implants with the same volume vary in their appearances based on their shape and height (ie "Projection"), there is NO accurate way to translate volume (in cc) to cup size, much less appearance.
There are a few facts that we all need to accept:
1. We ALL age. As we do our appendages, ears, noses and, yes, breasts, sag. The only ones who do not age are mythical gods, and we do not see them in our offices.
2. Since even feathers obey the laws of gravity and fall down, there is NO doubt that adding weight to a sag-prone appendage such as the breast will cause it to sag quicker. Obviously, the heavier the implant the faster the sagging.
So, how to pick THE PERFECT breast implant?
If you want fuller breasts then the only viable option is Plastic Surgery. Pills, yoga and exercises will not enhance and fill the breasts. After educating yourself, see one or more surgeons who are members of The American Society of Plastic Surgeons (ASPS) -wwwplasticsurgeryorg . They will educate you on the options which are best suited FOR YOU. A thorough examination, allowing you to see various implants are the LEAST you should settle for.
In my practice, we do 3D digital imaging with the VECTRA system which allows you to SEE YOURSELF the way you may look with every implant on the US. This has been popular with our patients because seeing is believing and helps them understand the ultimate differences between various implants.
Good Luck.
