What is breast fat necrosis?

Breast fat necrosis happens when an area of fatty breast tissue or adipose tissue becomes damaged or dies. This can occur when the blood supply to the fat cells is reduced or disrupted, meaning the tissue does not receive enough oxygen to survive.

When this happens, the body responds to the damaged tissue. This may lead to a firm lump, an oil cyst, tenderness, bruising, skin changes or a change in the shape or feel of the breast. In some cases, it may be uncomfortable or cause visible changes that affect the result of cosmetic breast surgery.

Although breast fat necrosis is not breast cancer, it can sometimes feel or look similar to more serious breast conditions such as early stage breast cancer. For this reason, any new lump, hard area or unexpected change in the breast should be assessed by a medical professional. Tests such as an ultrasound, mammogram or biopsy may be needed to confirm the cause and rule out other conditions.

In cosmetic surgery, breast fat necrosis may develop after procedures that involve trauma to fatty breast tissue, changes to the blood supply or fat transfer to the breast.

What causes fat necrosis of the breast?

Fat necrosis of the breast can happen when fatty breast tissue is damaged and its blood supply is disrupted. Without enough oxygen and blood flow, some of the fat cells can die. The body then reacts to this damaged tissue, which may cause a firm lump, tenderness, bruising, skin changes or changes in the shape of the breast.

In the context of cosmetic surgery, fat necrosis may occur after procedures that involve trauma to the breast tissue or changes to the way blood reaches the tissue. This can include:

• Breast reduction surgery: tissue removal and reshaping can affect the blood supply to areas of fat within the breast.
• Breast uplift surgery: repositioning breast tissue and the nipple area can place strain on the blood supply if not carefully planned and performed.
• Breast augmentation with fat transfer: also known as fat grafting, this involves moving fat from one part of the body and injecting it into the breast. Some transferred fat may not develop an adequate blood supply, which can lead to fat necrosis.
• Breast implant surgery: although less directly linked than fat transfer, fat necrosis may occur where tissue has been damaged during breast augmentation surgery or where healing has been affected.
• Revision breast surgery: further surgery on tissue that has already been operated on may carry a higher risk of disrupted blood flow and poor healing.

Can fat necrosis of breast tissue be caused by surgical negligence?

Fat necrosis is not automatically a sign of surgical negligence. It is a known risk of breast surgery and can happen even when a surgeon has acted with appropriate care. However, there are circumstances where it may suggest that the surgeon breached their duty of care.

Surgeons have a legal duty to assess whether you are suitable for surgery, explain the risks clearly, perform the procedure to a professional standard and monitor your recovery. If a surgeon fails to meet these obligations and you develop breast fat necrosis as a result, you may be entitled to claim compensation.

Negligence may have occurred if the condition was caused by:

Poor surgical technique

During breast reduction, breast uplift, breast reconstruction or flap-based procedures such as DIEP flap surgery, the surgeon must carefully protect the blood supply to the remaining tissue. If the blood supply is disrupted, the fat cells may not receive enough oxygen, which can lead to damaged or dead tissue.

Poor technique may include placing too much tension on a tissue flap, removing or repositioning tissue in a way that affects circulation, or failing to reconnect blood vessels properly where this is required. If these errors cause tissue death that could reasonably have been avoided, this may be considered negligent.

Issues with fat grafting

Autologous fat grafting, also known as fat transfer, involves removing fat from one part of the body and injecting it into the breast. This must be carried out carefully so the transferred fat has the best chance of developing a healthy blood supply.

If a surgeon injects too much fat into one area, the cells in the centre may not receive enough oxygen and may die. This can increase the chance of fat necrosis developing. While it is not always possible to prevent breast fat necrosis completely, poor fat placement, excessive volume in one area or failure to follow accepted clinical standards may indicate negligent technique.

Inadequate blood supply management

Whether a patient is having a smaller breast procedure or more extensive breast reconstruction, maintaining adequate blood flow is essential. This includes both arterial inflow, which brings oxygen-rich blood to the tissue, and venous outflow, which allows blood to drain away properly.

Some vascular problems are unpredictable. However, negligence may be suspected if the surgeon failed to assess risk factors before surgery, failed to plan the procedure properly or failed to monitor the tissue after surgery. If early signs of poor blood flow were missed, delayed or not acted on, this may have allowed the condition to worsen.

Failure to diagnose and respond to complications

Diagnosing breast fat necrosis usually involves a clinical assessment and may require imaging, such as an ultrasound or mammogram, to confirm fat necrosis and rule out other causes of a breast lump. If a patient reports pain, a new lump, skin changes or changes in breast shape after surgery, these symptoms should be assessed properly.

Negligence may arise if a surgeon dismisses symptoms without examination, fails to arrange suitable investigations or does not refer the patient for further medical assessment when needed. A delay in diagnosing breast fat necrosis may lead to avoidable pain, distress or further treatment.

Failure of informed consent

A surgeon must explain the recognised risks of surgery before the operation, including the possibility of fat necrosis where this is relevant to the procedure. This is especially important for procedures involving fat transfer, breast reduction, uplift surgery or breast reconstruction.

If you were not warned that fat necrosis was a possible risk, and you would not have gone ahead with the surgery had you been properly informed, this may amount to a failure of informed consent. Patients must be given enough information to make a clear and informed decision about whether surgery is right for them.

Fat necrosis can be a recognised complication, but it should still be taken seriously. If it was caused by avoidable surgical errors, poor planning, inadequate aftercare or a failure to explain the risks before surgery, you may have grounds to make a cosmetic surgery negligence claim.

What are the breast fat necrosis symptoms?

Recognising symptoms early can help reduce the anxiety associated with finding a new lump. It typically presents as a firm, round lump that is usually painless, though some people find symptomatic fat necrosis to be tender or even painful. These symptoms typically appear weeks or months after the initial tissue trauma.

Common signs include:

• Breast lumps: these may feel hard and fixed to the surrounding tissues.
• Dimpled skin: the skin over the area of necrosis may appear pulled in or pitted.
• Nipple retraction: if the necrosis is near the nipple, it may cause the nipple to pull inward.
• Skin changes: you might notice redness, bruising, or thickening of the skin.
• Oil cyst: sometimes, the damaged fat cells turn into an oily fluid, creating a cystic lesion.

Because fat necrosis can mimic breast cancer on physical examination and imaging, it is important to seek a professional breast examination and imaging to confirm the diagnosis. In many cases, symptoms may not become noticeable until months after the initial surgery or trauma.

How do you treat fat necrosis in the breast?

In many cases, treating breast fat necrosis is not medically necessary. Because it is a self-limiting condition, if the lump is not causing pain or significant changes to the breast’s shape, a doctor may suggest a “wait and see” approach. Many cases gradually improve as the body naturally absorbs the damaged or dead tissue.

However, if breast fat necrosis is confirmed and does not resolve on its own, or if it is large, painful or affecting the breast’s appearance, several treatment options may be considered:

• Fine needle aspiration: this can be used to drain an oil cyst, which may relieve pressure and discomfort.
• Surgical excision: if the necrosis is causing significant breast distortion or has formed a solid mass, the damaged fat tissue may be surgically removed.
• Fat grafting or local tissue rearrangement: depending on the size of the defect after excision, further surgery may be needed to restore the breast’s appearance. This may be considered after cosmetic breast surgery, breast reconstruction or breast conserving surgery where the shape of the breast has been affected.

While many cases go away naturally, it can take several months or even years for the fatty tissue to fully heal or for an oil cyst to dissolve. Your doctor may recommend monitoring the area during this time to check that the lump is not changing or causing further symptoms.
