I wear a 36B and I'm interested in a 745cc cup? What size is a 745cc?

Answers from doctors (6)


Patients often think in terms of cup size when considering augmentation. Unfortunately, devices are sized in terms of milliliters (cc) of volume. This can lead to some confusion when sizing. Additionally, it is important to remember that cup size itself is not standardized with variations from one manufacturer to another. Unfortunately, as many women can attest their cup size in an industry leader such as VS is not necessarily transferable to another brand.

Another point which is often underappreciated is that of anatomy and starting point. Any implant will add volume to the volume which is already present. The implant is additive. A particular volume will not necessarily confer the same cup size to different patients (often times it will not even confer the same cup size to different breasts in the same individual...remember they are "sisters" not "twins").

A general rule of thumb is that 125cc can represent somewhere between 1/2 to a full cup size increase. Smaller volume differentials (25-50cc) are typically less consequential representing a volume change of less than a shot glass. However, I have found these numbers, at least anecdotally, to be of little help. Patients often present with notions/goals which do not correlate with these sorts of sterile volumetric assessments.

When sizing patients, there are a number of useful tools including:

-3D imaging (has the added benefit of offering a volumetric analysis of the pre-operative breast)

-Breast sizers (rice bags)

-Goal photos

I also recommend that patients commit to a particular look rather than a cup size. Once a patient settles on a look that pleases them the overall cup size increase becomes less relevant. The key to obtaining a natural result is to stay within the parameters defined by your BWD.

It is difficult, if not impossible to accurately predict cup size. That being said, 745 cc implants are very large implants (on most frames). This will be a very significant upsize regardless of the label on the support garment.

As always, discuss your concerns with a board-certified plastic surgeon (ABPS).

There really isn't a great cc's to cup size guidance rule. For some reference, a pound of water weighs about 450 cc. So you are talking about a 1.6-pound total weight to each breast, which would be your own breast mass plus the weight of an implant. I would suspect a 745 cc cup to be in the full C-range for an average height patient but there are so many variables. It's actually interesting and curious that you are asking about a cup size in cc's as opposed to asking how big a cup you might expect if you, say, added 450 cc to your existing B-cup... That is a more common scenario to address in consultation. How is it you arrived at wanting a 745 cc cup - was this after doing some simulation in a plastic surgery office with computer systems or a sizing kit?

A 745cc breast implant would increase your cup size by about five! Approximately every 120-150cc of breast implant size increases the cup by about one. I specialize in extra large breast implants and you can find more info at XLbreastimplantsatinfo.com

Way too large, unless you are a large woman with a very wide chest. Breast implants should be biometrically planned to fit your body, and are not too large or too small for optimal results, comfort, maintainence of position, drooping etc. Thr larger the implant size, Tte greater the immediate and potential complications.

There is no correlation between implant volume in cc and bras. That isn't the optimal way of thinking about aesthetic goals. Go visit a few ABPS certified/ASAPS member surgeons that specialize in breast surgery. Best of luck! Instagram: @drgeraldminniti

It is not possible to tell you what cup size you will be with a 745cc breast implant. Ultimately, careful communication of your goals (in my practice, I prefer using pictures, direct examination/communication in front of a full-length mirror, in-bra sizers, and computer imaging) as well as careful measurements (dimensional planning) will be critical.

Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery regarding breast implant size/profile selection is:

1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.

2. Have a full discussion and communication regarding your desired goals with your plastic surgeon.This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals.

In my practice,using photographs as “goal” pictures (and breasts that are too big or too small for comparison) is very helpful. For example, I have found that the use of words such as “natural” or "C or D cup” etc means different things to different people, and therefore prove unhelpful.

As you know, cup size varies depending on who makes the bra. Therefore, discussing desired cup size may also be inaccurate. Again, the use of computer imaging has been very helpful during the communication process, in our practice.

3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.

I hope this helps.
