What Size is 550cc?

I find the best way to see what bra size an implant would be on you is to try the implants in bras on yourself. Whichever bra the implant fits appropriately in you is the right bra size. 3D imaging is also useful to see what a particular implant would look like on you.

   If you are an A cup now, you would likely be a D cup depending upon chest wall width, amount of breast tissue, and bra manufacturer.

There's no way to perfectly predict how a particular size of breast implant will affect your body. However, it is easy to say that bigger volumes typically result in bigger breast cups. Your body habitus has a lot to do with how much a certain size will enhance your breast cup. I have seen this size create mostly D and DD cups, but patients with higher BMI it can be a C cup.

There isn't an exact correlation between an implant size and final breast size.  The amount of breast tissue and breast size preop is one of the key issues.  If you have a small amount of breast tissue, a 550 cc implant would be more noticeable of a change.  Larger breasts and frame can tolerated a larger implant with only moderate change in cup size.  You will need a physical examination to determine which is more likely.   I would advise against being too focused on cup size as that is very fungible.  Cup size varies by bra company and measurement methodology.  It is more helpful to show your surgeon what you feel is a natural and ideal outcome with photos.  Trying implants under a bra can also help, but is less exacting.   It sound like you need to have more of a discussion about breast size with your surgeon.  Good luck!

 There are several variables in determining implant size.  When recommending implant size for my patients, I consider the followings: 1) patients' anatomy (height, weight, chest width, chest height, amount of breast tissue) and 2) patients' desired look/goal.  Without knowing your chest measurement and breast tissue amount, I cannot give you any recommendation.  You should visit with board-certified plastic surgeon who will examine you.  Try implant sizers to get a rough estimate of the size you may want.  As you know, bra/cup size will vary depending on the brand.  Good luck with you.

30cc is about the same as 1 ounce from your measuring cup in the kitchen. Therefore this implant is about 18oz or 3 cups. Bra cups do not however equal measuring cups so you won't necessarily go up 3 bra cup sizes. In the big scheme of things, this implant is also larger than the typical implant placed but depending upon your frame and desires it may be very appropriate.

While it is hard to know in any patient what volume of an implant will create what bra size, it is far to say that a 550cc implant in someone of your height and weight would make you a D cup. Whether that would be a small D or a bigger D would depend on how much natural breast tissue you have.

Hi Canh,

Your questions are very common during breast implant consultations. The answers will depend on a number of factors.


How big is too big? That depends on your expectations (subjective) and on your chest width and your breast base diameter (objective). The ideal breast size, like beauty, is in the "eye of the beholder". Discuss with your PS the potential long term consequences of "large" implants.

What size is 550cc? Differences in bra cup measurements vary from brand to brand so accurate post-op size predictions are difficult. Your PS might give you a "best guess" based on his experience.


Best of Luck!

An implant volume does not always match up with cup size because bra manufacturer's all measure differently.

Thank you for the question.

There is no absolute correlation between breast implant size and cup size. Be careful that you do not base your communication of goals and/or satisfaction with the outcome of breast surgery on achieving a specific cup size. As you know, bra cup sizes vary from one bra manufacturer to another.

 In my practice, I encourage patients to use goal pictures to communicate their goals;  I asked them to show us pictures of what they would like to achieve as well as pictures of breasts that are too big or too small…

 Also, since you mentioned that you have gained weight, it is best that you achieve a long-term stable weight prior to undergoing any type of breast surgery.

 I hope this helps.
