Will 500cc round silicone breast implants be too big on me small frame? I am 18 5’4 and 110 pounds. (photo)

Personally I would not go that large.  You might like them initially but with time find the weight uncomfortable.  But everyone is different. I just advise patients to think of the long term,  having seen plenty of women who wanted large implants only to which they had gone with something not so large.

Excellent question – breast implant size is a tough decision for many women who are having an augmentation because it is difficult to tell how implants will really look and feel before they are implanted. My initial advice is to work with your surgeon to get as close of an approximation as possible. Look at, touch and hold implants in different sizes; ask about sizer implants that you can try on. The reason I recommend this is that 500cc implants are on the larger end of implant sizing, and given your smaller frame there are some considerations involved. For example, you may begin to experience shoulder or back pain from adding significant weight to your chest. You may also find that larger implants begin to droop or look unnatural as your breast tissue changes over time.
However, I cannot say with certainty whether 500cc implants are “too big” for you. Implants of this size are likely to give you a dramatic boost in breast volume, lift and symmetry, which aligns with your desired outcome. And, if your surgeon is board-certified and experienced and has recommended 500ccs for you, then it is likely a safe decision that will deliver the aesthetic results you want. The most important thing is that you feel comfortable with the implant size and with your surgeon’s advice. You can always choose a smaller implant that does not come with as much concern, or get a second opinion from a different board-certified plastic surgeon for clarity. I wish you the best of luck!

Great question!  It is hard to say as we do not have any information as far as the measurements of your breast.  You generally want to pick an implant that is close to the diameter of your chest.  With that being said, a 500cc implant will provide you with approximately 2.5 cup sizes bigger than you are now.   You should have the opportunity to try on sizes in the office so that you have an idea of what they will look like.  You should also see more than 1 surgeon to get other opinions to understand what other doctors think and if everyone is recommending similar sizes, then it sounds like you should be good to go.
Best of luck and hope his information helps!

Your breasts are low on the chest wall, asymmetrical in size, shape, volume and you need a lift.  500 cc implants weigh 1 lb each and will descend inferiorly and laterally requiring a revision.  The technique I recommend is The Bellesoma Method.  This will reshape your breast tissue creating upper pole fullness without implants, elevate them higher on the chest wall and more medial to increase your cleavage.  Vertical scars are avoided, nipple sensation and the ability to breast feed are maintained.  At the same time or later, fat transfers can be performed if additional volume is desired.  Implants are not lifetime devices and half are removed by 9.5 years.  Fat transfers are permanent and incorporated into the body.Best Wishes,Gary Horndeski, M.D. 

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.The key to obtaining a natural result is to stay within the parameters defined by your BWD. 
Based on your photos, I would recommend conservative sizing. 500 cc is rather large on your small frame. the larger the implant the greater the risks and the shorter lived the result (due to the weight on the soft tissue).
As always, discuss your concerns with a board certified plastic surgeon (ABPS).
