How big do you think a 520 cc silicone implant under the muscle will be? I am 5'7" and about 120 lbs. (Photo)

A 520 cc implant on your size is going to be really big. Probably in the DD to DDD range. So, make sure that  this is the look that you want. Also, keep in mind that really large implants will definitely cause your breast tissue to sag over time. Best, Dr. Nazarian

Thank you for your question and photos.  520 cc's will give you a significant increase in volume.  To get a good idea of what you will look like, please as your board-certified plastic surgeon to "try on" the implants.All the best,Dr. ResultsMiami, FL

A 520 cc silicone implant under the muscle for someone who is 5'7" and 120 lbs will likely result in a significant increase in breast size, likely reaching a DD to DDD cup (keep in mind cup sizes are subjective). This is considered a large implant, especially for a smaller frame. It’s important to note that the final look can vary depending on factors like chest/breast width, existing breast tissue, and skin elasticity.
While 520 cc implants can provide a dramatic transformation, it's essential to consider the potential long-term effects, such as the risk of breast sagging due to the added weight. Some people may also experience discomfort or back pain, especially with larger implants. To ensure the best outcome, it’s important to discuss your goals thoroughly with an experienced plastic surgeon, try on sizers to visualize the result, and consider using tools like 3D imaging to predict the final outcome.

A 520cc implant on someone your size will be a very dramatic change. They will be large, and they will look like augmented breasts, so be sure that that is your goal! There is no direct correlation between implant volume and cup size, but I would guess this would put your cup size in the DD-DDD range. Assuming your base width is in the 12-13cm range, this will likely mean using an extra-full profile implant (or whatever the equivalent is in your surgeon's chosen implant)

Hello, there is no perfect correlation between implant size and final bra size because a person's own breast tissue has an effect on the final size.  Rather than focusing on cup size, surgeons will often as the person to look at before an after photos, or use other techniques like Vectra 3D imaging or sizers.

Hello,Thank you for your question and photo. My patients find it helpful to try on sizers in a sizing bra at my office with a form-fitting T-shirt. This gives you a 3D picture of what the volumes look like on you personally as everyone's frame, measurements and existing breast tissue will affect their results.All the best

It is important to realize that the ultimate breast size and shape depend upon so very many variables. A 300 cc implant on a petite woman with a thin frame may look quite large, but that same implant in an overweight woman may be barely noticeable. Size and shape of the result depend upon the volume of the implant, the shape of the implant, if it is over or under the muscle, your skin and its resilience, stretch marks, the degree of breast sagging, chest circumference, amount and distribution of the natural breast tissue, etc. For this reason, it is impossible to give reliable advice based simply upon height and weight, or even photos. The only way to approach reliable predictions is with an in-person examination with a board certified plastic surgeon, the use of sizers, 3-D imaging, and most importantly, relying upon the skill, expertise, and experience of your chosen Board-Certified Plastic surgeon.That said, some general predictions can be made. On your thin frame, implants over 500 cc will appear very large. They will not appear natural, and will definitely have an "augmented "look. This may be your goal, or may not be. The important thing is to realize that going with such a large implant has long-term consequences. You may be happy for the first two or three years, but five years from now you may end up needing a breast lift from all that weight. As well, potential back problems, etc. I generally counsel moderation in augmentation, but all this depends upon your consultation with her plastic surgeon.

Unfortunately 'big' is a very subjective term so it is difficult to answer your question appropriately. Hopefully you have chosen a well-trained, and reputable surgeon and you can trust their opinion based on their exam and discussion with you. You are starting with a good breast shape and size so you should have a nice outcome following surgery. 520cc seems somewhat large and will likely look fairly fake if that is what you are looking for. Hope this helps.Josh Olson MD

I appreciate your question.



It depends on your chest wall
measurements and existing breast tissue as implant size does not accurately
correlate to a bra size. It also depends on the brand and style of bra
you wear as size varies from manufacturer to manufacturer.During your breast augmentation
consultation, you should feel the different types of implants available, and
try on various implant sizers in front of a mirror to help you to get an idea
of how you will look following the surgery. You should also bring pictures of
the look you would like to achieve, as well as a favorite top to wear when
trying on implant sizers.

The best way to assess and give true
advice would be an in-person exam.

Please see a board-certified plastic
surgeon that specializes in aesthetic and restorative breast surgery.



Best of luck!

Based upon your photo and description, I would anticipate that you would end up in a full D or DD bra.  You appear to have a thin chest diameter, and I would definitely recommend a higher profile implant.  This should prevent an abnormal side breast appearance and also reduce the risk of rippling.Good luck with your surgery.
