If you have breast implants, or you are thinking about getting them, you have probably come across the term capsular contracture and wondered how worried to be. It is a fair question, and it deserves a calm answer.
Capsular contracture is when the soft scar tissue that forms around every implant tightens and squeezes it. Most women never develop a severe form. Still, it helps to know what it looks like, what may cause it and what can be done, so you can act early if something changes. Here is the full picture, from the perspective of Dr Benjamin Norris, a Specialist Plastic Surgeon in Sydney.
What is capsular contracture?
Your body treats an implant as a foreign object. That is normal. It builds a thin layer of scar tissue around the implant, called a capsule, and in most women that capsule stays soft and goes unnoticed.
In capsular contracture, the capsule thickens and tightens. The Therapeutic Goods Administration (TGA) lists it as a known complication of breast implant surgery, and the RACGP guide for general practice describes it as the most common reason for revision surgery.
It can affect one breast or both. It can show up in the first few months or many years later. It does not mean you did something wrong, and it does not mean the implant itself is faulty.
What does capsular contracture look and feel like?
Changes are usually gradual. Common signs include:
- One breast feeling firmer than the other
- An implant sitting higher than it used to
- A rounder, ball-like or distorted shape
- A sense of tightness across the chest
- Tenderness or pain, which tends to come later
Early firmness often does not hurt, so it is easy to brush off. In the first weeks after surgery, some firmness and swelling is expected, and our guide to post-op symptoms and what is normal explains the difference. Sudden swelling, warmth, redness or fever are different. Those point towards infection or a fluid collection, and you should call your surgeon the same day.
The Baker grades explained
Surgeons describe capsular contracture using the Baker scale, from Grade I to Grade IV. It is a clinical judgement made by examining the breast, so two surgeons may occasionally grade a breast a little differently.
| Grade | How it feels | How it looks | Usual management |
| I | Soft, like a natural breast | Natural, no visible change | No treatment, routine follow-up |
| II | A little firm | Looks normal | Monitoring, often with imaging if anything changes |
| III | Firm | Visibly rounder or distorted, implant may sit higher | Surgery is usually recommended |
| IV | Hard, often tender or painful | Obvious distortion | Surgery is usually recommended |
Grades III and IV usually need surgery.
What causes capsular contracture?
Nobody knows the exact cause. Researchers have several main theories, and more than one may be at work in the same woman:
- Bacterial biofilm. A thin, low-grade layer of bacteria on the implant surface may keep the capsule inflamed and prompt it to tighten.
- Haematoma or seroma. A collection of blood (haematoma) or clear fluid (seroma) around the implant after surgery may irritate the tissue.
- Radiation to the chest is the risk factor most clearly linked to contracture, which is why contracture is more common in women who have had breast cancer treatment.
- It slows healing and affects blood supply to the tissue.
- Implant rupture. A leaking implant can trigger a stronger scar reaction.
- A previous contracture. If you have had one, you are more likely to have another.
These are theories, not certainties. A woman can do everything right and still develop contracture, and another can have none of these factors and still be affected.
Can you reduce your risk of capsular contracture?
You can lower it, but no method removes it.
On the surgical side, several decisions matter. These include where the implant sits (above or below the chest muscle), the position of the incision, careful control of bleeding during the operation (haemostasis), and strict infection-control technique. Dr Norris will explain which techniques he uses, and why, at your consultation.
There are also a few things you can do yourself:
- If you smoke, quit well ahead of your operation
- Stick to the aftercare plan you are given
- Tell your surgeon about swelling or any new change early instead of waiting it out
Who performs your surgery matters as well. A Specialist Plastic Surgeon in Australia has completed years of accredited surgical training and holds the FRACS (Plast) qualification, and you can check any practitioner’s registration on the AHPRA register. Our guide to maintaining your breast implants covers what ongoing care looks like.
Is capsular contracture dangerous?
Usually not to your general health. It can be uncomfortable and it can change the shape of the breast, but it is not a cancer and does not spread.
There is one catch. Firmness that appears late, sometimes years after surgery, can occasionally be a sign that the implant has ruptured. That is why a new change deserves proper assessment, often with an ultrasound or MRI.
Contracture is also different from breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). BIA-ALCL is a rare cancer of the immune system, and its most common symptom is swelling of a breast from fluid build-up, according to the TGA. You can read more in our article on the low odds of ALCL.
How is capsular contracture treated?
Monitoring for Grades I and II
Mild contracture is usually watched rather than treated. Dr Norris will examine you at regular reviews and may suggest imaging if something shifts. Many women stay at this stage indefinitely.
Non-surgical options
Breast massage is sometimes suggested, but the evidence for it is limited. Medicines used off-label for contracture are not a standard treatment in Australia. If you have read about them online, please ask your surgeon before trying anything.
Surgery
For moderate or severe contracture, surgery is usually recommended. Depending on your situation, it may involve:
- Capsulotomy: the tight capsule is cut open so it stops squeezing the implant.
- Capsulectomy: some or all of the capsule is taken out. Taking out all of it is called a total capsulectomy.
- Implant exchange: the old implant is replaced with a new one, often at the same operation.
- Pocket change: the implant is moved to a different space in the breast.
- Implant removal: the implant comes out and is not replaced.
Which approach suits you depends on the grade, the type of implant, your breast tissue and your goals. Recovery depends on what is done, and Dr Norris will explain the timeline and activity limits before you book. As with the first operation, expect some swelling and soreness for a few weeks.
One more honest point: contracture can come back, even after revision surgery. Taking out the whole capsule and changing the implant pocket can lower the chance, but it cannot rule it out. The Cleveland Clinic notes that removing a hardened capsule can also relieve pain.
When should you see your surgeon?
Book a review if you notice any of the following:
- New firmness in one or both breasts
- A change in breast shape or implant position
- Pain or tightness that is new or getting worse
- One breast looking different from the other
- Swelling that appears months or years after surgery
You do not need to wait for an annual check. If something feels different, it is worth a call. Form & Face provides ongoing post-operative follow-up so changes can be assessed early.
Ask your surgeon whether they contribute to the Australian Breast Device Registry (ABDR). It records implant and surgery details so long-term safety can be tracked, and you can opt out if you prefer.
All surgery carries risks, including bleeding, infection and the need for further operations, and you can read more on our surgery risks and complications page. Under the Medical Board of Australia’s cosmetic surgery guidelines, you will have two pre-operative consultations and at least a seven-day cooling-off period before surgery can be booked. Dr Norris asks for a GP referral, and a second opinion is always welcome. Patients under 18 have a longer, three-month cooling-off period and an assessment by an independent psychologist, psychiatrist or GP.
Frequently asked questions
What is capsular contracture?
Capsular contracture is when the natural scar capsule around a breast implant tightens and squeezes it. The breast can feel firm, look distorted or become painful. It is the most common long-term implant complication, but most women never develop a severe form.
What are the first signs of capsular contracture?
Often it starts with one breast feeling a bit firmer than the other. The implant may sit higher or look rounder, and the chest can feel tight. Pain usually comes later, if at all. If one breast changes, book a check with your surgeon.
Is capsular contracture dangerous?
Capsular contracture is not usually dangerous to your general health, but it can be uncomfortable and change breast shape. Late firmness can sometimes signal implant rupture, so any new change should be assessed by a Specialist Plastic Surgeon, often with an ultrasound or MRI.
Can capsular contracture go away on its own?
Usually not. Once a contracture has set in, it rarely softens by itself. Milder cases (Baker Grade I or II) are often just watched over time. Grades III and IV generally need surgery, which may involve removing the capsule and replacing the implant.
How can I reduce my risk of capsular contracture?
You can reduce your risk by not smoking, following your post-operative instructions and reporting swelling early. Your surgeon lowers risk through implant placement, careful technique and strict infection control. No method removes the risk completely.
Can capsular contracture come back after surgery?
Yes, capsular contracture can recur after revision surgery, especially after radiotherapy or a previous contracture. Removing the whole capsule, replacing the implant and sometimes changing the implant pocket can lower the chance of it returning.
Does Medicare cover capsular contracture surgery?
A Medicare rebate may apply to some revision surgery for symptomatic capsular contracture, but only when strict clinical criteria are met, and it is never guaranteed. Dr Norris can explain eligibility and likely out-of-pocket costs at your consultation.
