Size estimate with 600cc saline implants?

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 under appreciated 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.
With regards to your specific question, without pre-op pictures it is impossible to guess the final volume as your ultimate outcome is the sum of implant plus native breast tissue.
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

Dear Rational603079,
breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.

Bra cup sizes aren’t standardized so trying on sizers while wearing a bra in the size you’d like to be would probably be the easiest way to determine what size you’d be after surgery. 600cc is quite a large implant so there will most likely be a significant increase in cup size.

I recommend an in person consultation with a plastic surgeon to discuss your goals and be measured. After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size implants. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what is right for them.

600 cc implant weigh over 1 lb each, will most likely result in breast descent and possible neck, shoulder and back pain. At size 36, each 200 cc of implant corresponds to 1 cup size change. You will go up 3 cup sizes to a H. I strongly recommend you do not go with 600 cc implants.

I'd suggest doing 3D breast implant imaging. the technology can control for implant shape, volume, and projection.

While it’s challenging to precisely predict the appearance of breast implants without an in-person consultation, 600cc saline implants could result in a noticeable increase in size. The final outcome depends on factors like your existing breast tissue, chest dimensions, and body type.


Best of luck !

If you are truly a DD, please don't get 600 cc's. Each cup increase is about 150 cc's in most women. You would go up to FF. This will be too large and heavy for most women and sag over time.

It's difficult to determine the bra size you'll wear after 600cc implants, but it will be multiple cup sizes. It's best to visit with a board certified plastic surgeon near you for guidance. She/He is your personal expert in selecting the implant that will be fit your body and matches your goals. I've included a video on implant selection that I hope you find helpful.
