I selected 560cc, should I go for it or is that too big for my frame? (Photo)

It is hard to give a definite answer your question. Many things should be considered when breast implants, such as breast width, the amount of breast tissue and body fat, elasticity of the the tissue, etc. The most important is how you want to look. We have the patient show us how they want their breasts to look using breast sizers during their consultation and trust us to provide the correct result. 

You need a formal evaluation by a licensed plastic surgeon and expert in breast augmentations to determine what is best for you and your goals.Proper breast enlargement is not a "cookie-cutter" procedure where the same technique is applied to every patient. Every woman who comes to my practice has unique needs and different goals for her breast augmentation. As a board-certified plastic surgeon, I always listen carefully to each woman's concerns and thoroughly discuss the key points of the procedure. I also take into account their overall height and weight, the size and shape of the underlying chest and ribcage, the tightness and elasticity of the skin, and the amount of natural breast tissue. Prior to the procedure, we discuss and make decisions regarding location of the incision, whether to place the implant under or over the chest muscle, and what type of implant to use (I offer multiple types of silicone gel breast implants, as well as saline implants).
My experience performing thousands of aesthetic breast surgeries in a wide anatomical range of patients enables me to achieve consistently beautiful and natural results that are customized to each patient’s body type and goals. These results are the product of extensive communication, meticulous planning, and skillfully executed surgery.
I suggest consulting with a board-certified plastic surgeon and expert in Breast Augmentation surgeries. - Dr. Cohen

Depending on the individual anatomy and desired results, estimations and measurements should be made for each patient individually. The elements that form up the breast shape and size and the overall frame can be different in each person. It is best to consult a board certified plastic surgeon who is experienced in cosmetic breast surgery in person and discuss your goals and options after a physical examination.Hope this helps,Ali Rıza Öreroğlu, MD FEBOPRASEuropean and Turkish Board Certified Aesthetic, Plastic and Reconstructive SurgeonIstanbul, Turkey

It is impossible to answer your question based on the information provided. Many things must be considered when choosing the correct implant for a given patient. These include breast width, the amount of breast tissue and body fat, elasticity of the the tissues, to name just a few . The most important consideration is how you want your breast to look. In my opinion, only your surgeon has the knowledge and experience to make make the correct selection, and it should be their responsibility. In our practice , we have the patient show us how they want their breasts to look, and trust us to provide the correct result. This avoids much of the anxiety patients experience over this issue.

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.
With regards to your specific question, "too big" is relative. As long as you have been accurately sized according to your unique BWD, you should be fine. Without measures, it is difficult to offer more concrete advice.
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

None of the modalities to approximate final results from breast implants are 100% accurate; they merely facilitate the patient and the board certified PS concurring on the size and type of breast implant which will come the closest to reaching the patient's goal. My patients prefer to try on sizers under garments they typically wear to determine if they fit as expected and to help allay some of their trepidation associated with this decision.
Have another preliminary conversation with your PS and ask to try on a profile bra with silicone 505cc HP/560cc or maximum 610cc XHP implants under a tailored blouse, tight sweater, swimsuit, workout clothes, tank tops, and other garments you typically wear so that you have the best idea of whether the garments fit as desired with the implant selected. The most important clinical factor in determining breast implant size is the base width or diameter of the patient’s native breast. If the patient would like more volume to obtain a larger cup size, the implant profile can be shifted from a moderate profile implant to higher profile implant. I would recommend that you go with the size that boosts your self-esteem, and fits your anatomy.  Choosing an implant based on an aesthetic goal that exceeds your anatomic capacity may lead to complications and possibly revision.
In the OR, leave it up to your PS's experience, technical skill, surgical acumen, and detail-oriented specificity to select the implant that comes closest to the agreed upon aesthetic improvement with your anatomy.

The implant size you selected is big, no question about it.   But it is not ridiculous   The right size is very subjective but you can go on different surgeons websites where the implant size are indicated to give you a better idea.

560 cc implants weigh more than 1 lb each and it would be almost impossible to place them totally submuscular.  They will extrude inferior and lateral or the surgeon will have to cut your pectoralis major muscle, both of which are undesirable.  I recommend you consider smaller implants.    Best Wishes,Gary Horndeski, M.D.

Dear kikinga7,
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.

Thank you for sharing your excellent question.  Unfortunately it is impossible to recommend the best implant style, size or shape without an in-person examination that allows for the measurement of key breast parameters, as well as permits an in-depth discussion as to your desired goals and outcome. I would recommend seeing additional ASPS board certified plastic surgeons to ensure that the implants you decide upon are the right ones to meet your expectations.  It sounds as if it may be wise for you to "try on" several of the implants so that you can have a better visual representation as to what they would look like.  Best wishes!
