Breast Enlargement & Augmentation

Breast Enlargement Surgery

Breast enlargement surgery, also known as breast augmentation, is one of the most regularly performed procedures in the UK and involves the insertion of implants under the breast tissue to increase the size or change the shape of the breasts. Many women choose to have breast augmentation surgery to boost body confidence and to feel comfortable with the size and shape of their breasts. 

"Breast surgery continues to be one of the most common procedures in the UK. By using mentor we can insert the implants in a way that suits you to hide and minimise any scarring" Simon Smith, Medical Director at The Harley Medical Group.

There are a multitude of reasons why our patients are happy with the results:

About Breast Enlargement | Harley Medical Group

At The Harley Medical Group, all of our medically led team of Surgeons and Cosmetic Surgery Nurses have years’ of experience and all are registered with the General Medical Council (GMC). Patient care is our number one priority, and that is why we insist on a minimum of two pre-surgery consultations, a full assessment of your current health and medical history, and ongoing post-operative care.

The operation is carried out under a general anaesthetic, your Consultant Anaesthetist will speak to you about this on the day of your operation. The operation time will vary from patient to patient and can take up to an hour. The surgeon will make an incision in the skin about 3 to 5cms long, usually in the crease below the breast but incisions can also be made in the underarm or around the areola (nipple).  Your surgeon will discuss the appropriate incision in your case. 

The surgeon will then create a pocket for the implant to be placed in and this can be between the breast tissue and chest muscle (sub glandular placement) or behind the chest wall muscle (sub muscular placement). Some surgeons use what is called a “dual plane” placement and in this case the implant will be placed partly behind the breast tissue and partly behind the muscle. The size and shape of the breast, the looseness of the skin and your own anatomy will determine which position the surgeon feels is the best option for you and this will be explained and discussed at your consultation. 

Surgeons at The Harley Medical Group use the Keller Funnel™ to introduce the implant into the created pocket rather than the traditional method of the surgeon using their gloved fingers. This medical device provides a low friction or less traumatic insertion method for silicone gel implants and means a shorter incision length. It is also believed to reduce the risk of potential infection which can otherwise occur by contamination from the patient’s skin. 

The incision will be stitched and these may be dissolvable stitches rather than ones which require removing and they will be covered by dressings and then a sports type bra which you will be advised to take with you. There may be drainage tubes in place which will be removed before you go home. You will be advised beforehand whether your surgery is being performed as a day case or if you will need to stay overnight. However, don’t forget that even day case patient can occasionally need to stay overnight if they are initially not well enough to go home. 

From your very first consultation with one of our Cosmetic Surgeons you will have a committed nursing team to talk you through the surgery and to provide all of the support you need.

You can see what the implants might look like after the surgery with our Virtual Breast Enlargement tool.


At The Harley Medical Group we endeavour to provide the best for our patients; the best procedures, the best care and the best results. Which is why we are always looking at ways to improve our offering to ensure we achieve this.

We are delighted to announce that with every breast enlargement procedure our expert cosmetic surgeons will be using a Keller Funnel. The Keller Funnel is an FDA (US Food & Drug Administration) approved device which has multiple benefits including a shorter incision length, meaning fewer stitches are required and scarring is reduced. In addition, the funnel aids implant placement and reduces friction so there is also less post-operative bruising and faster recovery time.

Ask one of our medical professionals at your free, no obligation, consultation for more information about our expert breast surgery techniques.




After the surgery you will be required to wear a post-surgical bra (similar to a sports bra) 24-hours a day, to support and protect your breasts after the surgery. Every patient is different but a full recovery is usually made between four and six weeks, returning to work after just one to two weeks depending on the nature of your occupation.

Breast Enlargement Aftercare | The Harley Medical Group

Before leaving the hospital you will be given a full guide to help you to make a full and speedy recovery, along with a phone number so that you can call any day, any time that you need us. You may require a night or short stay in hospital to have your progress monitored, but you should be back to work in one to two weeks depending on your occupation, and a full recovery should be made between four and six weeks after surgery.

It is important that you take things steady when you return home in order to rest and to fully recover from the surgery. We recommend that women who have a Breast Enlargement have an MRI scan three years after the surgery, and every two years after that, to ensure that everything is as it should be.

After surgery with The Harley Medical Group you are one of our patients forever, meaning that we are here for you whenever you need us.

Further, Mentor Memory Gel implants has one of the best warrantees on the market.

• Free automatic enrolment
• Lifetime product replacement in case of confirmed rupture
• In the case of confirmed rupture, up to €1000* of financial assistance, for a period of 10 years from the date of its implantation

You have changed my life. Thank you!


The shape was always there, however the size wasn't, which made me feel very self-conscious when wearing dresses.

What does the procedure entail and how long does it take?

The procedure usually takes between one and two hours to complete, is carried out under general anaesthetic and may require an overnight stay in hospital so that your progress can be monitored.

Your cosmetic surgeon will begin by making small incisions in the natural crease underneath the breast, in the armpit or the underside of the nipple area. They will then insert the implant either behind or over the muscle and breast tissue to give a natural shape before closing the incisions with surgical sutures. Your surgeon will advise which position will deliver the best results for you. You can discuss the procedure in more detail with your cosmetic surgeon during your consultation.

Is Breast Enlargement right for me?

People choose to have Breast Enlargement for many different reasons. The procedure is most suitable for and most commonly performed on patients with small breasts, asymmetrical breasts or breasts that have lost volume or shape due to weight loss or pregnancy. There is no right or wrong reason to have the procedure but what’s essential for all patients is that you do thorough research and talk to your chosen cosmetic surgeon.

How much does Breast Augmentation cost?

Prices for breast augmentation surgery start from £4,450.

As the procedure is different for every patient, there is no set price. An accurate cost can be given following consultations with your cosmetic surgeon, this will address whether you need an overnight stay and all aftercare appointments.

Am I too old / young?

Breast Enlargement surgery is not recommended for women who have not fully developed, as the body shape can change a lot, naturally. To have this procedure at The Harley Medical Group, you must be over 18 and in good general health. Your cosmetic surgeon will have access to your medical records too, so they will be able to advise you on whether the procedure is suitable for you. We thoroughly assess all patients, regardless of age so please book a free consultation to find out if you’re a suitable patient.

Is it possible/safe to breastfeed with breast implants?

Yes absolutely. It is important to let your surgeon know if you plan to have children and breastfeed as it may influence where the incisions are made.

What is capsular contracture?

Capsular contracture is when natural breast tissue (from scar tissue and collagen) can form around the implants, which in time may thicken and harden the breast. This can cause discomfort and the breasts to look and feel different. 

When you have Breast Enlargement surgery, your body will usually form a layer of healthy tissue around the implant to make it a part of your body. This thin layer of natural breast tissue is called the capsule and is a natural and healthy part of the healing process. If you’re experiencing redness, inflammation or pain, you should always contact your clinic immediately. 


What are the Benefits of Mentor Breast Implants?

At The Harley Medical Group we use Mentor breast implants. Mentor, a Johnson & Johnson brand, has been producing the highest quality breast implants for more than 20 years. They are approved by the US FDA (Food and Drugs Administration), come with a 10-year warranty and exceed CE and MHRA testing standards following more than 20 years of clinical data. They are also the UK’s leading provider of implants for breast reconstruction patients. 

How do I choose the right cup size?

Choosing the right size is crucial and this will be a big part of your surgical consultations. The sizes available to you will depend on your current breast size, your build and the amount of loose fat or skin in the chest area. We recommend that you don’t increase your breast size by more than one or two cup sizes. 

How long will it take me to fully recover?

Every patient is different so recovery times for breast enlargement surgery can vary, however we usually expect patients to make a full recovery and return to normal activities four to six weeks after surgery. Most people return to work one to two weeks after the procedure.

As part of the recovery process, you will need to wear a special, supportive post-surgical bra 24 hours a day. This is a bit like a sports bra and is designed to support your new breasts and protect them during the healing process. 

Will I be left with scars?

Surgical incisions are made in the most discreet places possible. This means that scarring is minimal and usually hidden in the armpit or under the natural creases of the breasts. Any scarring you are left with will fade over time until you are left with very faint marks that are barely noticeable.

How long do breast implants last?

We use Mentor breast implants and these come with a 10-year warranty (which includes free replacement in the case of capsular contracture.  It’s important to bear in mind, breast implants will usually last between 10 and 12 years, after which they’ll need to be replaced.

Do I need to take any long-term precautions after Breast Enlargement surgery? 

No. The only precautions you’ll need to take are any that you took before you had your surgery. There are many myths surrounding breast implants and flying for example, but these have no basis in truth.

How do I choose a reputable cosmetic surgeon?

It is important that your cosmetic surgeon is fully qualified and experienced. To make sure your cosmetic surgeon is reputable, ensure the clinic is registered with the Care Quality Commission (CQC) or The Healthcare Inspectorate Wales (HIW). You should also look for cosmetic surgeons who are registered with The General Medical Council (GMC) and ask if they are carrying out cosmetic surgery procedures on a daily basis. Because the procedure is different for every patient, there is no set price. An accurate cost can be given following consultations with your cosmetic surgeon and this will include an overnight stay and all aftercare appointments.

What aftercare is available to me?

A high level of aftercare is crucial after any surgical procedure, that’s why you’ll only ever deal with qualified, caring professionals at The Harley Medical Group.  From your first free consultation, to the dedicated check-ups following your procedure, you’ll have a committed nurse and surgeon team to guide you through. As our patient, we will do everything we can to ensure you have a full and speedy recovery.  Before you leave the hospital you will be given full post-operative advice, as well as a phone number you can ring 24-hours a day if you have any questions or concerns. We pride ourselves on always being there to put your mind at ease in the weeks, months and years following Breast Enlargement surgery.  We recommend that women with silicone gel-filled breast implants have an MRI three years after the procedure and every two years after that. It’s also important that you get into good habits straight away, by checking your breasts regularly for any changes in the shape, size or position of your implants.

What happens if I have an implant rupture?

We care about you and that’s why we use Mentor implants. We are completely confident in their high quality and very low rupture rate and that’s why they come with a Lifetime Replacement Policy for confirmed rupture. In this unlikely event, you will be entitled to free implant replacement regardless of the age of the implant. 

How soon after my procedure can I go on a sun-bed?

While at The Harley Medical Group we do not recommend the use of sun-beds under any circumstances we understand that they are a popular way to prepare the skin before a holiday. We recommend waiting for six weeks (by this time you will not have to wear your sports bra) before going on the bed, and then only if your nurse and surgeon have confirmed the wounds have healed normally. The incisions must be covered for the duration and we recommend also using at least SPF25 on them for additional protection. The scars should be white before they’re exposed to the sun, new skin can pigment if exposed to UV. 

How soon after my procedure can I fly?

If your surgeon is happy with the way you are your healing you can fly two weeks after surgery, however at The Harley Medical Group we highly recommend you wait for at least six weeks to ensure you are fully healed. This is also a practical recommendation, until six weeks post operation of your breast augmentation you will be unable to wear a bikini, go swimming in the pool, spa or sea or lift your luggage... which doesn’t make for the most entertaining holiday.  

What are the risks?

The risks with Breast Enlargement are the same as with any surgical procedure that requires general anesthetic. Capsular contracture   is the most common complication of Breast Enlargement surgery. The risks and details of the procedure will be fully explained during your consultation. 

What is ALCL?

ALCL stands for Anaplastic large cell lymphoma, the full title is Breast Implant Associate Anaplastic large cell lymphoma (BIA-ALCL), and is an extremely rare cancerous tumour that can potentially grow around breast implants. ALCL affects between 1 and 3 in a million (or 0.0003%) women who have implants.

It usually presents with a sudden swelling in the breast surrounding an implant, although can present with a mass. It usually happens many years after the implants have been placed, an average of 8 years.
Most cases are easily treated by having the implant removed, along with the capsule that surrounds it (total capsulectomy).

Simon Smith, our Medical Director, comments:

 “BIA-ALCL is very rare - between 1 and 3 in a million, and can affect  women having implants placed for cosmetic or reconstructive reasons.  It seems likely that few women are likely to change their mind about  implants, but they should have full awareness of this condition before  agreeing to implants, as part of their consent process.

Women who have implants already, certainly should not be alarmed, but  if they get a sudden swelling in their breasts, they should seek a  referral from their GP to their local breast unit, who will follow  guidelines set down by the ABS to ensure that there is no underlying serious cause for it. Treatment for BIA-ALCL is usually simple, but it must be actively managed.”

Patient safety has been and always will be our priority which is why we recommend Mentor implants.  MENTOR® Breast Implants are backed by substantial clinical data demonstrating safety and effectiveness in patients having undergone primary and revisionary augmentation and reconstruction surgeries. Mentor continues to support ongoing inquiries into the association of ALCL and breast implants.

Will the implants come with a warranty?

Mentor Memory Gel implants has one of the best warrantees on the market "You can’t put a price on peace of mind. So neither have we".

Limited Warranty Plan for Mentor® and PERT HESE™ Silicone Gel-filled Breast Implants*

** For all other MENTOR® and PERTHESE™ Breast Implants,please refer to the Mentor Lifetime Product Replacement Policy

What is the difference between round and CPG (teardrop) breast implants?

The only difference between the round and the CPG (teardrop) breast implant is the shape. Both implants have the same unique, patented Memory Gel and outer shell and both come in a variety of projections and sizes. Most importantly both implants are tested to the highest exacting standards. 

A round breast implant, currently the most popular style in the UK, looks like half a sphere is no defined top or bottom. Round implants give a full look directly under the nipple area providing the classic augmented appearance. 

The CPG implant, also known as teardrop or anatomical implant, is currently the most widely used implant in the world. Teardrop implants have less volume towards the top of the implant and are fuller at the bottom, more closely resembling the look of a natural breast. Teardrop implants do have a slightly longer recovery time, but produce a far more natural result, which is becoming increasingly popular.

What is a CPG Implant?

The Contour Profile Gel (CPG) breast implant, also known as an anatomical implant, is the teardrop shaped implant that is designed to follow the curves of your body. The implant has less volume towards the top and are fuller at the bottom, result is a more natural looking fuller breast. This style of implant is the most requested across the world, particularly in Europe and America, and is growing in popularity in the UK where the trend for more discreet implants is growing. 

How do I choose the right size?

There is no formula to select the exact CPG style for a given patient, nor is there a single right answer. In general, the lower the height and the greater the projection, the more the breast will look round. The final selection should always be left to the surgeon, as they will know the shape with which they could most enhance a breast.

What is a Keller Funnel?

The Keller Funnel is an FDA* approved medical device that allows the surgeon to position the breast implant with minimal contact to the implant itself. This means that the implant never meets your skin during surgery ensuring it remains perfectly sterile. The funnel also allows the surgeon to make a smaller incision, which  means that recovery time after surgery should lessen as the procedure is less impactful on the body.

At The Harley Medical Group we believe this is the safest ways to perform breast enlargement surgery, which is my we have made it policy that all procedures are undertaken with a keller funnel as standard, and at no cost to our patients.
