Can 300cc-3500cc Breast Implants Increase Size from 34A to C?

I am 25 years with no kids, 5'7" tall at 135 lbs. I am considering having breast augmentation. I am currently a 34A and would like to be a full C after surgery. Would 300-350cc do that, or would I need to go larger?

A little larger breast implants might be better

Based upon your body type, a 350 cc implant may get you into a C range. There a lot of factors to consider, even more than just implant volume. Do you want to be a full C or just a C? Do you have any droop to the breast or just not enough volume? Etc.

We fully evaluate the chest diameter, distance from the neck to the nipple, and current breast volume. I have found over time, that most women who "just want to be a small C" wish they had gone a bit bigger after surgery is complete. The 350 cc implant in a person of your body type will be "just a C". A saline implant can be slightly over inflated, while a silicone implant is just that size with the same dimensions. Remember that one size larger implant is only one ounce more of fluid(30cc). So the difference may just give you the fullness you are looking for.

Good Luck!

C cup breast

 No one can guaranty a cup size. But to answer you question, usually 300cc to 350 cc  would change a 34 A to a C.

Breast implants

This would be a great question for someone that has actually seen you in person. But at 5'7" it sounds like you would need more cc's.

Breast implant size

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" 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 press 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.

Cup size and breast implants

It is very difficult to "nail down" cup size for a patient because the bras are so variable in shape and determination of cup size. The best way for you to figure out what you like is to sample some implants and put them in a loose bra while wearing a blouse over it. Choose the volume don't worry about the cup.

Imaging would REALLY help to visualize potential results.

In this situation, it’s virtually impossible to make a specific recommendation regarding breast implant size without performing a physical examination or viewing pictures.When choosing breast implants for breast augmentation we’re not interested in size, but instead we’re interested in the appropriate implant fit.We want to achieve harmony, balance and proportion with the surrounding structures.
In your case it might be possible to obtain a C cup with a 300 to 350cc implant.Unfortunately, everyone’s idea of a C cup isn’t the same, and for this reason cup size is a frequent source of confusion.
For this reason, we feel that it’s important to have a consultation with a board certified plastic surgeon.In an effort to minimize confusion we utilize both implant sizers and the 3D Vectra computer imaging system.These two systems help the surgeon understand the patient’s aesthetic goals. They also significantly alleviate the anxiety that many patients experience regarding breast implant size.When this approach is taken patients are ultimately happy with breast implant size, and the procedure is associated with high levels of patient satisfaction.

Hello! Thank you for your question. In general, implant size does not correlate with bra cup size. The cup size itself will vary from manufacturer to manufacturer as well as who is doing the actual measurements. Thus, cup size is never a reliable indicator for your breast size. I typically encourage my patients not to communicate her desires in cup size but more on the actual look and appearance. Given your desires, a breast augmentation, with an implant or fat grafting, would be an ideal procedure that would meet your expectations. Breast augmentation is now the most popular procedure performed in plastic surgery today. One tolerated very well by women with minimal downtime and high patient satisfaction.

Good communication between you and your surgeon of your expectations is warranted - choosing your surgeon wisely is the first step. Discussion of your wishes and having an honest and open dialog of your procedure is mandatory (e.g, implant type, incision, placement, etc). Your height, weight, breast width, and body habitus will make a difference for which implant style/projection to choose. Implant profile will also make a difference on the projection, which will influence overall breast/cup size. I have found that photographs brought by the patient is helpful to get a visualization of the appearance you wish for in terms of size, shape, fullness, etc. In addition, your surgeon's pre and postoperative photographs should demonstrate a realistic goal for you of results. Sizers are helpful during an in-office consultation. Once this has been accomplished, allow your surgeon to utilize his/her best medical judgment during the procedure to finesse the best possible result for you after preoperative biodimensional planning and fitting the right implant for your breast width. This is the most important determinant for the sizing of implants, which will provide the optimal result and most aesthetically-pleasing result for you.

Consult with a board-certified plastic surgeon well-versed in breast procedures who will examine and discuss with you the various options and factors to consider and help you decide which one will be the right one for you. Hope me that this helps! Best wishes for a wonderful result!

There is no way to guarantee a particular bra size. Bra sizing varies greatly between bra manufacturers and a C in one bra will be a D in another. What matters more than the assigned bra size is the way the implant looks on you. The best option for your body and aesthetic goals can be determined in a thorough implant sizing session.

Implant sizing depends on several factors. One of the most important factors is your breast width. Generally, your surgeon will measure your breast width, and then provide you with a range of implant sizes appropriate for your native breast size. There are more nuances to it than just what I've described, but this approach works for most women.

I usually have my patients bring in a large bra and a tight t-shirt to do sizing. I'll then choose 3-4 implants that I feel are appropriate, and have my patients place them in the bra under the tight t-shirt. My patients can then look in the mirror and get a good sense of what they will look like with the provided implant sizes. My patients like this approach and get a great idea of how they will look.

By using this technique, your surgeon can outline a range of appropriate implant sizes that will be aesthetically pleasing, and you make the final decision.

I hope this helps. Good luck!

Breast implant size to change A cup to C cup

Thank you for your question. Size varies with breast manufacturer, thus a C cup at one store can be called a D cup at another store.

It is best to consult a plastic surgeon who is certified by the American Board of Plastic Surgery, who is experienced in cosmetic breast surgery and has an excellent reputation in your community.

During your consultation the plastic surgeon will take biometric measurements of your chest and breasts and based on these measurements recommend an implant size that is appropriate for your body. In addition breast implant sizers can be placed into your bra to give you an idea of how you will look. You may also visit to see examples of patients who have gone from an 8 to a C cup and see what size breast implants they have had.
