Facing a mastectomy is one of the most frightening things a person can go through. If you are reading this, you may have just received a diagnosis, be in the early stages of planning treatment, or be trying to process a conversation you were not expecting to have.

Breast reconstruction surgery is not a requirement and some patients choose not to have it, which is an equally valid decision, but for many women knowing that reconstruction is possible and understanding exactly what it involves makes the prospect of mastectomy far less overwhelming.

What is breast reconstruction?

Breast reconstruction is a surgical procedure (or series of procedures) that rebuilds a breast mound following the removal of breast tissue during mastectomy, and the goal is to restore breast shape and, in many cases, symmetry with the opposite breast.

It is important to be honest about what reconstruction can and cannot achieve. Reconstruction creates a breast mound, but it is not the same as your original breast. Sensation in the reconstructed breast is often altered or absent, though this can gradually improve over time, particularly with certain techniques. The appearance and feel of a reconstructed breast is generally very good, but results take 12 to 18 months to fully settle, and some patients benefit from additional minor procedures such as nipple reconstruction or contralateral breast adjustment once the main reconstruction has healed.

Reconstruction is performed by a consultant plastic or oncoplastic breast surgeon, often working alongside your breast cancer surgeon, and it can be discussed as part of your overall breast cancer treatment plan from the outset to enable you to have the information you need to make an informed decision without feeling rushed.

Immediate versus delayed breast reconstruction: which is better?

There is no universally correct answer to this question. Both approaches have real advantages, and the right choice depends on a combination of clinical and personal factors.

Immediate reconstruction

Immediate reconstruction takes place at the same time as your mastectomy, under the same anaesthetic. The advantage is that you wake from surgery with a breast shape already in place, which many patients find less distressing, and it also tends to produce better cosmetic results because the skin envelope is preserved.

Immediate reconstruction however is not always the right option. If you need radiotherapy after your mastectomy, this can affect the reconstructed tissue and implants, and radiotherapy to an implant significantly increases the risk of capsular contracture and poor cosmetic outcomes. In those cases, delaying reconstruction until radiotherapy is complete is often the more sensible clinical choice.

Delayed reconstruction

Delayed reconstruction is performed weeks, months or even years after the original mastectomy. It allows you to complete cancer treatment (chemotherapy, radiotherapy or both) before undergoing reconstruction. It also gives you more time to research your options, process the diagnosis and make a decision that feels right for you.

Delayed reconstruction does mean living without a breast mound for a period of time, which some patients find difficult. Prostheses and specialist bras can help during this time. The cosmetic outcome of delayed reconstruction can be excellent, although the surgical technique may differ slightly from immediate reconstruction.

Implant-based breast reconstruction

Implant-based breast reconstruction uses a silicone or saline breast implant to recreate the breast mound. It is the most commonly performed type of breast reconstruction and is generally the less complex surgical option.

There are two main approaches within implant-based reconstruction:

Tissue expander followed by implant

A tissue expander is a temporary, adjustable implant placed under the chest muscle at the time of mastectomy. Over the following weeks and months, saline is gradually added to stretch the skin and create a pocket of the right size and shape. Once expansion is complete, a second operation replaces the expander with a permanent implant. This staged approach is very common and allows for careful shaping of the final result.

Direct-to-implant (one-stage) reconstruction

In selected patients (particularly those undergoing skin-sparing or nipple-sparing mastectomy), it may be possible to place a permanent implant in a single procedure without the expander stage. This is only suitable where there is sufficient skin and soft tissue remaining, and where the size requirements are not too large. A mesh (acellular dermal matrix or synthetic mesh) is often used to support the implant.

Implants have a finite lifespan of typically 10 to 20 years, so you may need further surgery at some point in the future to replace them.

Radiotherapy to the reconstructed area increases the risk of complications such as capsular contracture (scar tissue forming around the implant) and this is a key consideration when deciding between implant and flap reconstruction.

Autologous (flap) breast reconstruction: DIEP and other options

Autologous reconstruction uses your own tissue, taken from another part of the body, to create a new breast. The tissue used is called a flap. The most commonly performed flap technique is the DIEP flap, though several other options exist.

DIEP flap reconstruction

DIEP stands for deep inferior epigastric perforator. In a DIEP flap procedure, skin and fat from the lower abdomen are removed and transferred to the chest to create a new breast. The blood supply to the tissue (the deep inferior epigastric vessels) is carefully preserved and reconnected to vessels in the chest using microsurgery.

The DIEP flap is widely regarded as the gold standard of autologous reconstruction because it does not sacrifice the abdominal muscle, which means core strength is preserved. The surgery takes approximately 6 to 8 hours and requires a hospital stay of 4 to 6 nights. Recovery is longer than implant reconstruction, typically 6 to 10 weeks before returning to light activity.

Because autologous tissue ages naturally with your body, the results of DIEP flap reconstruction tend to be very long-lasting and feel more natural than implants. The technique is particularly well suited to larger breast sizes where it would be difficult to achieve symmetry with an implant alone.

Other autologous options

• LD flap (latissimus dorsi flap): tissue from the back, including the latissimus dorsi muscle, is brought forward to the chest. This is sometimes combined with an implant to achieve the desired volume. Recovery is shorter than DIEP, but the technique involves a scar on the back.
• TRAM flap: uses abdominal tissue including muscle. Less commonly used now that DIEP flap is established, as the DIEP approach preserves the abdominal muscles.

How do you decide which type of reconstruction is right for you?

There is no single formula for this decision. In my experience, the most common concern at this point is that patients worry they might choose the wrong option, and a second opinion is always a reasonable step if you want one. What I want to reassure you is that both implant-based and autologous reconstruction can produce excellent results in the right patient. The decision is about finding the right fit for your individual circumstances.

The factors that influence the choice include:

• Whether you will need radiotherapy, which may affect suitability for immediate implant reconstruction
• Your body shape and the volume of tissue available for a flap
• The size of the breast being reconstructed
• Your overall health and fitness for a longer operation
• Your personal feelings about scars, recovery time and the use of implants
• Whether reconstruction is to be immediate or delayed

The comparison table below gives an at-a-glance overview of the two main approaches:

These differences are discussed in detail during your consultation. Reconstructive decisions are never made in isolation, and they are always made in collaboration with your oncology team to ensure the plan supports your cancer treatment first and foremost.

What does breast reconstruction surgery involve?

The specific steps of your surgery will depend on the technique chosen. There are, however, some elements common to all reconstruction procedures.

All breast reconstruction is carried out under general anaesthetic. You will be admitted to hospital on the day of surgery or the evening before, and before the procedure you will meet your anaesthetist and have the opportunity to ask any final questions.

Surgical markings are made while you are standing, which helps achieve the best possible symmetry.

Implant-based surgery

If you are having a tissue expander placed at the time of mastectomy, the procedure adds approximately 1 to 2 hours to the overall mastectomy time. The expander is placed in a pocket under the pectoralis major muscle, or under the skin with mesh support. Drainage tubes are placed during the operation and usually removed 1 to 3 days after surgery.

The expansion process begins a few weeks after surgery. Saline is added to the expander at regular clinic appointments until the desired volume is reached. The second operation to exchange the expander for a permanent implant is performed under general anaesthetic and usually requires 1 to 2 nights in hospital.

DIEP flap surgery

DIEP flap surgery is performed by a specialist microsurgeon and typically takes 6 to 8 hours. The lower abdominal tissue is carefully raised, preserving the deep inferior epigastric blood vessels, which are then connected to blood vessels in the chest under a microscope. Drain tubes are placed at both the chest and the donor site on the abdomen. Most patients require 4 to 6 nights in hospital.

Nipple and areola reconstruction, if desired, is generally performed as a separate minor procedure once the breast mound has fully settled, usually 4 to 6 months after the main reconstruction. Medical tattooing can be used to recreate the areola colour.

Recovery after breast reconstruction

Recovery time varies considerably depending on the technique used and your individual health. The figures below are general guidance and your care team will provide you with a personalised recovery plan.

Implant-based reconstruction

• Hospital stay: 1 to 2 nights for immediate reconstruction, and 1 to 2 nights for the implant exchange procedure
• Return to light daily activities: approximately 4 weeks
• Return to desk-based work: 4 to 6 weeks
• Return to driving: when you can perform an emergency stop comfortably, typically 4 to 6 weeks
• Strenuous exercise: 8 to 12 weeks, and your surgeon will advise
• Final result visible: 3 to 6 months after the last procedure

DIEP flap reconstruction

• Hospital stay: several nights
• Return to light daily activities: 6 to 8 weeks
• Return to desk-based work: 6 to 10 weeks
• Return to driving: typically 6 to 8 weeks
• Strenuous exercise: 3 to 4 months
• Donor site (abdomen): takes several weeks to heal, and the scar usually sits below the bikini line
• Final result visible: 12 to 18 months after surgery

During recovery you will be seen regularly in clinic to monitor healing and the progress of your result. If you are having adjuvant treatment such as chemotherapy, the timing of surgery is planned carefully to minimise any impact on your treatment schedule.

Risks and realistic expectations

All surgery carries risk, and breast reconstruction is no exception. It is important that you have a clear and honest picture of what to expect.

General surgical risks (all reconstruction types)

• Bleeding and haematoma
• Infection
• Wound healing problems, particularly in patients who have had radiotherapy or who smoke
• Anaesthetic complications
• Deep vein thrombosis (DVT) and pulmonary embolism, and you will be given preventative medication and compression stockings

Implant-specific risks

If you already have implants and are experiencing problems, see our guidance on breast implant issues.

• Capsular contracture: scar tissue forming around the implant causing firmness, distortion or discomfort
• Implant rupture or deflation
• Implant displacement or rotation
• Rippling (visible implant edges through skin)
• Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL): a very rare type of lymphoma associated with textured implants, and smooth implants are now preferred in most cases
• Need for further surgery to replace or remove the implant

DIEP flap-specific risks

• Partial or total flap loss: very rare but serious, and the blood supply to the flap is carefully monitored in the first 48 hours after surgery
• Donor site complications: wound healing issues, seroma, weakness (less likely with DIEP than TRAM)
• Abdominal scar
• Hernia at donor site: uncommon with DIEP technique

Realistic expectations

A reconstructed breast will look different from your natural breast.

Scars will fade over 12 to 24 months but will not disappear, and sensation in the reconstructed breast may be significantly reduced or absent, though some patients report gradual improvement over the years following surgery, particularly with autologous reconstruction.

Asymmetry between the reconstructed and natural breast is common, and many patients opt for a minor procedure to the opposite breast to improve balance.

Revision surgery is a normal part of the reconstructive journey, not a sign that something has gone wrong.

The final result is typically assessed at 12 to 18 months, at which point any refinements can be discussed.
