How to Decide Which Size Breast Implants to Get
15th May 2013
Breast implant selection is not straightforward, particularly when patients have misconceptions about the size of their breasts.
Our head surgeon, Dr Azhar Aslam identifies critical variables and gives guidance for patients and surgeons on working together for the best result.

Breast enlargement is the most popular cosmetic surgery procedure in the UK. The increasing popularity and accessibility of cosmetic surgery has seen a significantly increased demand.
Yet, few patients truly understand the risks, limitations and long-term effects. Although the past few years have seen much media hype associated with the good effects of breast augmentation, most information is less than satisfactory.
An even more disturbing fact is that, due to lack of proper training, few surgeons really understand the factors and variables paramount in achieving a good, long-term result.
Everyone knows that a breast augmentation involves adding an implant onto pre-existing breast tissue, but relatively few patients and surgeons grasp the relationship of patient desire, expectations and the physical aspects of volume enlargement.
If you’re a patient, this is what this post will help you to understand so you can arm yourself with the correct knowledge before seeing a surgeon.
A cosmetic surgeon has to look into the future to visualise the desired final result after the healing process is complete, taking into account the physical characteristics unique to each individual.
Even more importantly, a cosmetic surgeon has to delve into the patient’s mind to ascertain what the patient dreams of, wants, desires and expects. Understanding this is fundamental to a successful cosmetic surgery operation.

Most patients try to describe their desired result in vaguely defined concepts and unquantifiable terms. In my experience, many female patients are even unaware of what a breast cup size means and how cup sizes are measured.
Without the basic understanding, achieving patient expectations may be impossible.
Hence, educating the patient to make her understand her own desires and relating them to the limitations imposed by her own body and tissues is the most significant contributor towards patient satisfaction.
For many surgeons and patients, proper implant selection is an art, not a science. No single method has been proven to predict the size or shape will provide long-term satisfaction.
With detailed patient education, discussion, counselling and respect for implant soft tissue dynamics, the rate of dissatisfied patients can be reduced significantly.
The goal of augmentation is to improve the size and the shape of breasts. And while this creates a more positive self-image, the only predictable change is larger breasts. Positive psychological effects are common but are not necessarily predictable.
At the beginning of each consultation, patients are asked about two elements of what they seek.
Understanding the answer to the first gives a clearer picture of the motivation behind why they are seeking surgery and makes it easy to root out misconceived expectations and to filter out an obsessive element of the patients desire.
The answer to the second question helps the surgeon to define and quantify the patient’s desire in physical and measurable terms.
Patients seeking breast augmentation fall into three broad categories:
• young patients whose breasts have not grown to achieve a ‘normal fill’;
• patients, mostly in their 30’s, who have suffered the effects of pregnancy related changes and those related to weight fluctuations; and
• middle-aged patients, late 40s onwards, who have started with small breasts and have changed further because of ageing.
All practising surgeons have come across patients who have complained that their desired cup size has not been achieved. This has been despite the insertion of the desired volume and good, aesthetic results.
The discrepancy between a cup size and the volume arises because a cup size is not a scientific measurement and means different things to different people.
In this regard, patient education is crucial, as almost all patients will indicate the desired cup size they want.
However, if at this stage one asks the patient what she means, almost always it’s the case that she does not specifically know the size of a particular cup.
Cup size is extremely variable and inconsistent from one brand of bra to another, and it should be pointed out and explained that a cup size is only a general guideline and can’t be ordered or delivered.
Bras in the UK are normally sized in A, B, C, D… up all the way to the middle of the alphabet.
But cup sizes for breast augmentation are measured differently, in cubic centimeters. You might see this shortened to CC.
It works out differently for each body type, but a rough guide is that every 150cc’s, the breasts tend to increase about one cup size.
Again, it’s important to note this could vary on your body shape/type and even which store you shop for your bras in.
Bra size is not a measurement of a particular volume. Rather, it takes into account the volume as well as the dimensions of the breast.
The same volume placed in two women will create a different tissue stretch during healing and settling.
This means that the same volume can achieve different dimensions in different bodies and, hence, the importance of a patient’s tissue characteristics as well as difference of the cup size.
We always point out to the patients that they will be measured as different cup sizes by different shops. As well, if they pick up the same size bras from different manufacturers, these will be different in terms of proper fitting.
Hence, the most crucial piece of information that a surgeon must pass to the patient before the surgery — precise cup size cannot be guaranteed.
It is, however, not as despairing as it sounds. With proper measurements and accurate assessment of tissue characteristics, it is almost always possible to choose an implant volume in that will match the patient’s desire.
That we do not guarantee this to the patient does not mean we do not endeavour to achieve it and find the right breast implant size in cubic centimeters.

Once the surgeon has quantified the patient’s desire, defining the implants volume is the most important decision. This is the single most important determinant of failure or success of the operation.
The answer to the question — how much breast is enough? — depends on breast size in proportion to body size; the characteristic of each woman’s breast skin; and breast tissues.
The variables affecting the final breast size are numerous, but the most important are:
This is, of course, ultimately the most important factor. The skill is to reconcile the patient’s desire with the appropriate volume, taking into account this may involve a patient’s desire to modify and create realistic expectations, which will lead to patient satisfaction.
For example, a patient may desire a D cup. However, a surgeon may assess that the volume needed to achieve the patient’s desire, in adding to the pre-existing volume, may cause tissue damage.
In such cases, a detailed explanation is necessary to change the patient’s desire, or to explain the consequences, in terms of changes in the future and what other corrective surgery may need to be performed if the patient were to fulfil her desires and go ahead with what is seen to be a larger implant.
A breast cannot be seen in isolation as if hanging in the air. It has to be seen always in relation to the body.
Hence, assessing the patient’s build in height and weight, and assessing the shoulder and hips provides a basic measurement.
The base width of the breast is the most important dimension.
A second important measurement is the distance between the nipple (NAC) and the inframammary crease (IMC) as shown in the image.
Others are the distances between both anterior axillary lines and the distance of the nipples from the sternal notch.
The most important element to measure is the thickness of the breast tissue. This will determine whether there is adequate cover for an implant.
However, most surgeons make the mistake of taking absolute thickness as the important measurement.
Thickness of the tissue should always be judged against the intended volume of the implant. In other words, the bigger the volume, the more the desired thickness.
Thickness of tissue is not enough to provide adequate cover if the quality of these tissues is not good.
By quality, I mean the adherence between the skin and breast tissue to act as a single unit and envelope.
If the skin comes away from underlying tissue, the thickness needed to provide cover to the implant will have to increase significantly.
Every woman’s breast skin can stretch and enlarge by only a certain amount without sustaining damage, such as excessive stretching and thinning.
It is crucial to understand that any implant adds volume into the breast. This is extremely important in groups two and three, as their breast tissue and ligaments have already been damaged. The stronger the breast ligaments, the more volume they can hold.
It is important to remember, as well as to remind the patient, that the final volume achieved is the total of pre-existing breast volume plus the volume of the implant inserted.
No surgical option is without trade-offs. The question is how to pick the option that maximises the benefits and minimises the trade-offs.
Perfection or change to a different breast is never an option. Improvement in the existing breast is the only realistic alternative.
No plastic surgeon can totally predict what a patient’s tissues will do over time, but every surgeon and patient should consider these issues when making implant choices.
No implant will produce the same result in two patients as already explained.
This actually depends on your desired result.
What’s considered a large breast implant size for one body type, might be considered average or even small-sized for women of a different body type. We again have to look at things in terms of “volume”.
It is crucial to understand that a range of volumes, instead of a specific volume, will result in a specific cup.
For example:
In patients with a height range of 5’2-5’7 (about 158-173cm)
A weight range of 8.5-9.5 stones (about 52-58kg)
Chest measurements, generally are 29-32 cm.
To achieve a C cup in such patients, a volume range of 265-330g is generally needed.
The precise volume depends on the pre-existing breast volume, the thickness of tissue, expected tissue stretch and the strength of the holding ligaments.
Similarly, the distance between the NAC and the IMC influences the cup size (more information on NAC and IMC can be provided during your consultation).
In the frame range mentioned, a distance of 9-11cm will achieve the basic dimensions of a C cup requirement.
This means that, if the distance between NAC and IMC is less, it will need to be increased in addition to an adequate volume.
On the other hand, if this distance is more, then the patient should be informed that the cup size dimensions are already bigger than the desired cup — in this example, C. It will be a rare situation when she doesn’t already know this.
In such cases, the loss of volume has resulted in the loss of cup size, but the dimensions are still intact. Hence, a smaller volume, compared with the dimensions needed to reduce the cup size.
This relationship between dimensions and volume is crucial to understanding cup sizes as generally spoken by patients.
For most plastic surgeons, choosing the correct volume is less of a science and more of an art, based on their personal experiences.
The main advantage of such tests is not their accuracy but the onus they place on the patients to contribute in the decision making and in helping them understand the limitations a surgeon faces.
Identifying critical variables and decisions in order to create a simple system to provide surgeons with guidance is desirable.
Many surgeons in busy practices find it difficult to adopt such a system 100 per cent, due to their cumbersome nature.
First, the distance between two anterior axillary lines (AA) is measured.
Next, the NAC to IMC distance and sternal notch to NAC distance is measured (as shown in image).
Then an implant with the base size of half the AA measurement is chosen.
The base size of such an implant will be only slightly larger that the base size of the breast, hence, creating fullness both medially as well as laterally (fullness both towards and away from your body).
In plain English, the medial fullness gives cleavage and the lateral fullness balances the shoulder and hips and creates the female curviness.
The volume of this implant is noted and based on the patient’s desire, the pre-existing breast tissue, expected change in dimensions and desired shape; this volume is increased or reduced in 20g increments.
Almost always, adjustments and ideal implant volume can be found in the +/- 40-50g range.
This section might get a bit sciencey! As described, the second important measurement is NAC-IMC distance.
In an aesthetically appealing breast, the wider the breast, the longer this distance.
Determining optimal inframammary fold position at the end of breast augmentation is a major factor that affects the aesthetic result and achieves a certain cup size.
We take the following general guideline to achieve proper cup size and use the right size implants:
The chosen volume is then inserted with the incision placed according to the measurement given, taking into account any stretch that may have taken place, hence the volume and the measurement help the desired cup size.
This is a simple and effective method.
As mentioned, the concept behind this is by performing breast enlargement using this method, the whole figure is enhanced.
The importance of explaining this to the patient is she understands the breast sits on the body and the breast implants operation is being performed to enhance the whole body.
Each individual has her own special needs and desires, and once the volume has been determined, the shape, feel and projection of the implants should be explained.
Lastly, the issue of the cup size and the impossibility of guaranteeing a precise cup size should be emphasised.
The main aim of cosmetic surgery is to make a patient happy; this aim should never be ignored for any surgical procedure.

This article just provides general guidelines, and each patient, should, of course, have their own tailored operation. If your surgeon is not willing to have these discussions with you, it should raise a red flag.
