What Cup Size Would a 500cc Implant Give Me?

It is very difficult to determine the exact size and shape implant you will require to best match your ideal breast image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your breast will determine, in many cases, the maximal volume per implant profile that you can accommodate. To illustrate; a 100 cc difference may make a significant difference with a narrow base width breast, but much less of a difference if you have a wide chest wall and wide breast “foot print”. Therefore, just because your friend may have a great result with let’s say a 500 cc implant to make her go from a “A” cup to a “C+” cup size does not mean that you will have the same result with the same size implant. . Further simply placing implants in a bra to determine the size best for you is not always accurate as the bra often distorts the size, is dependent on the pressure the bra places plus the implant is outside your breast and not under it among other variables. Computer software morphing programs that automatically determine the best implant size can be helpful in some but not all cases (e.g. doesn’t work well in my experience with existing implants, sagging or asymmetric breasts). Using “want to be” photos however are useful if simply provided to the surgeon as I will further explain in the below link.

This would potentially increase your cup size by 2.5-3 cup sizes, depending on your band size.  However, it's important to also assess the width of the breast, and make sure that the implant isn't overly wide, and to assess the amount of "give" in the tissue, to know whether the high profile 500cc implant will fit you.  An in-person exam, by an experienced plastic surgeon, would help with this.

Obviously one of the most important aspects of breast augmentation surgery is the size.  This also tends to be the most complicated aspect of this procedure as well.  There is a lot that makes up a persons cup size and there are many measurements that I perform to determine if a particular implant size would work for my patient.  Every body is different as every breast is different.  A particular cc that may work and give an amazing outcome to one patient, may wind up be disastrous for another.  Every case is customized and what works for one may not work for another.
I spend one visit in its entirety to determine the implant size that is going to achieve what the patient desires.  There are the measurements, photos, at home sizing and in office sizing that we evaluate before coming up with a particular cc.
I would recommend you visit with a board certified plastic surgeon who would go thru all those maneuvers to try to achieve the optimum result for you.Therefore without a proper exam it is impossible to tell you what cup size you would be, and even then it is still very difficult as every bra company sizes their bras differently.
Hope that helps.
