Breast implant size/cup size?

Thank you for the question.

The more breast surgery I do the more I realize that there is no correlation between the size or model (profile) of implant used and resulting cup size.  This may have to do with several factors including: the amount of breast volume the patient starts with, the shape of the patient's chest wall (concave or convex), the type and model of breast implant selected (saline/silicone  and low/moderate/high profile), bra  manufacturer variance  in cup sizes, the  degree  of filling of the cup  with breast tissue,  and the subjective differences in patients perceptions of cup size. 
Much of the final “look” achieved after breast augmentation surgery  depends on several factors:

1. The initial shape, size (volume of breast tissue), symmetry of the patient's breasts. In general, the better the  preoperative breast appearance the more likely the breast augmentation “look” will be optimal.

2. The experience/skill level of the surgeon is important in determining the final outcome. For example, the accurate and gentle dissection of the breast implant pockets are critical in producing  long-term  well-placed breast implants. I personally think that these 2 factors are more important than any others, including type (saline or silicone)  or model (low/moderate/high profile)  of implant.

3. The type of implant used may  determine the final outcome, especially if the patient does not have significant covering breast or adipose tissue. For example, some surgeons feel that silicone implants have a more natural look and feel than saline implants because silicone gel has a texture that is similar to breast tissue. Each patient differs in the amount of breast tissue that they have.  If a patient has enough breast tissue to cover the implant, the final result will be similar when comparing saline implants versus silicone gel implants.  If a patient has very low body fat and/or very little breast tissue, the silicone gel implants may provide a more "natural" result.
On the other hand, saline implants have some advantages over silicone implants. Silicone implant ruptures are harder to detect. When saline implants rupture, they deflate and the results are seen almost immediately. When silicone implants rupture, the breast often looks and feels the same because the silicone gel may leak into surrounding areas of the breast without a visible difference.  Patients may need an MRI to diagnose a silicone gel rupture.   Saline implants are also less expensive than the silicone gel implants.
Other differences involve how the breast implants are filled. Saline implants are filled after they’re implanted, so saline implants require a smaller incision than prefilled silicone breast implants.
On May 10, 2000, the FDA granted approval of saline-filled breast implants manufactured by Mentor Corporation and McGhan Medical. To date, all other manufacturers’ saline-filled breast implants are considered investigational.
As of 2006, the FDA has approved the use of silicone gel implants manufactured by the Mentor Corporation and Allergan (formerly McGhan) for breast augmentation surgery for patients over the age of 22.

4. The size and model of breast implant used may  make a  significant difference in the final outcome. Therefore, it is very important to communicate your size goals with your surgeon.  In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or “C cup” or "fake looking" or "top heavy" means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.
I use  intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the breast implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison.
I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible.
By the way, the most common regret after this operation, is “I wish I was bigger”.

I hope this helps.

I think you've got your no answer


Although everything that has been posted in answer to your question is correct, it is likely that you will have a full D cup breast after lift and augmentation with 350cc implants.  If that sounds too large for you, then you should choose a smaller implant or have some tissue removed during the lift procedure.  Discuss it with your plastic surgeon and let him/her know your goals.  Good luck!

Cup Size and Breast Augmentation

Cup sizes after breast augmentation is tricky to predict.  If you are a C cup and adding 350 cc you will be a large D or DD if I had to guess.  I really try to get my patients to focus less on the "CUP SIZE" and to focus on our goal to produce full, nicely shaped breasts that fit the patient's body frame.

How much bigger would a 350cc Breast Implant Make me?

It is obvious that you and your surgeon worked very hard to pick the best implant for YOUR chest and breast tissue. But- I am also sure that a colleague of mine who is that meticulous and dedicated to detail also must have told you that there is NO direct and predictable correlation between an implant volume and bra cup sizes. Bra cup sizes VARY ENORMOUSLY between different manufacturers (A C cup in one is never a Ccup in another and they do not all feel "right" because they are NOT the same). As a result, it is ethically impossible to predict bra cup size based on implant volume. I THINK you will go up just over a cup size in your particular bra line. I would encourage you to stay with your surgeon. It is much more important to have an implant picked which fits your chest than trying to fill a desired scientifically inaccurate bra cup. Good Luck.

The results from 350 cc breast implants

There is not a direct correlation between cup size and implant size. However, 350 cc breast implants would probably result in a D or DD cup. 

The size of the implants are based on a combination of a patient's goals and objectives and her anatomy. In order to provide a natural looking augmentation, the surgeon needs to evaluate many factors including soft tissue coverage, skin laxity, chest wall width, breast imprint width, the shape of the breasts and relative level of constriction to ensure that the breast implants are appropriate for your body.

350cc Silicone - Approximately How Big Will my Breasts Get?

This is a good question and it seems obvious that by knowing the implant size you could then predict the final bra size. However, it's actually more difficult than that. Unfortunately, bra cup sizes are not standardized and vary between manufacturers. In my office, I encourage my patients to not focus on the cup size of the bra, but instead find a goal look that they like. If we accomplish that goal look, then the procedure is a success and we only find out the bra size once a formal bra fitting has been performed. It's a rough estimate, but in general every 150-200 cc of breast implant will increase the breasts size by one cup.

Size after augmentation

If you are a C cup and get 350 cc implants, you'll likely be a full D (approximately). However, remember that bra size will vary depending on where you're sized (Victoria's Secret vs. Nordstrom etc...) so that indicates that it is a variable rating, and should not be too much of a concern. As long as you feel comfortable in the implant size when you do your sizing, you should like the volume after surgery no matter what a retailer sizes you as. Best of luck!


It is somewhat difficult to predict, but most likely for you a cup size is going to be about 200cc.  I would predict you will go up in size 1-2 cup sizes, depending on the bra, with implants of this size.    I predict you will be in the full D cup size range.

Cup size

This is a very common question. The reality is there is no way to determine what YOUR cup size will be for a few reasons.
First, cup size is determined by each store and even in each store you will find different cups that fit you. For example, Victoria's Secret has different lines and each line has a slightly different fit. There is even a store in Manhattan that will tell you you are a C cup even if you are flat chested just to give you an ego boost.
Second, each patient likes a cup size that fits HER best in her own opinion. I've had patients who are clearly in the A cup range who don't mind "swimming" in their big bras filled with "chicken cutlets" and I've had other patients who were clearly in the D cup range who like the look of "popping out" of their bras so they wear B cup bras.
Since cup size is both made up by stores and based on the individual style of the patient, it is impossible to predict.
With that said, I use cup size as an idea of what style patients want. Meaning, if a patient is an A cup and says "I want a D," it's a certain implant, whereas the same patient saying "I want a B" is a different implant.
Hope that helps.

Size after breast augmentation

Much discussion surrounds breast size after surgery with my patients. Many factors come into play. It is not just as simple as using a larger implant. Tissue shape, skin excess or deficiency and implant style also are a factor and you should consider all prior to surgery.
