What is capsular contracture?
Capsular contracture is a tightening and thickening of the natural scar tissue that forms around a breast implant, which can make the breast feel firm, look rounded or distorted and, in more advanced cases, become painful.
Whenever a foreign object such as an implant is placed in the body, the body walls it off with a thin layer of scar tissue called the capsule. This is normal and expected. In most women the capsule stays thin and soft, holds the implant in position and cannot be felt.
In capsular contracture, the capsule gradually becomes thicker and starts to shrink. Because the implant cannot shrink with it, the capsule squeezes the implant. This is what causes the firmness, the change in shape and sometimes discomfort.
Capsular contracture is one of the most common reasons for further surgery after breast augmentation and after implant-based breast reconstruction. It can develop at any time, but it is most often noticed within the first one to two years after surgery. It usually affects one breast, although both can be involved.
It is important to know that capsular contracture is not cancer and is not dangerous in itself. It is a problem of comfort, shape and appearance, and there are effective ways to treat it.
What are the Baker grades of capsular contracture?
The Baker classification grades capsular contracture from I to IV, where grade I is a normal, soft breast and grade IV is a hard, painful and visibly distorted breast.
The scale was developed for cosmetic breast augmentation and is still the system most surgeons use to describe how severe a contracture is. A modified version is often used after reconstruction, because a reconstructed breast never feels quite like a natural one.
| Grade | How the breast feels | How the breast looks | Usual approach |
|---|---|---|---|
| Grade I | Soft, like a natural breast | Natural | No treatment needed |
| Grade II | A little firmer than normal | Still looks normal | Usually observation |
| Grade III | Firm | Visibly abnormal: rounder, higher or distorted | Surgery is often considered |
| Grade IV | Hard, often tender or painful, may feel cold | Clearly distorted | Surgery is usually recommended |
Grades I and II are often called “clinically insignificant”, meaning most women do not need any treatment. Grades III and IV are the ones that usually lead women to seek advice, because the change is visible and may be uncomfortable.
The grade is decided by a clinical examination. Imaging is not needed to grade a contracture, although an ultrasound or MRI scan may be arranged to check the implant itself, for example to look for rupture.
What are the symptoms of capsular contracture?
The main symptoms of capsular contracture are a breast that feels increasingly firm or tight, an implant that looks rounder or sits higher than before, visible distortion, and in severe cases aching or pain.
Symptoms usually come on gradually over weeks or months. Common signs include:
- One breast feeling harder or tighter than the other.
- The implant appearing more rounded, “ball-like” or less natural in shape.
- The implant riding higher on the chest, sometimes with the nipple appearing to point downwards.
- Visible edges, folds or rippling that were not there before.
- Asymmetry between the breasts that has developed over time.
- Tenderness, a feeling of pressure, or pain, particularly when lying on that side or during exercise.
Some changes can look similar to capsular contracture but have a different cause. A breast that suddenly becomes swollen, larger or tender months or years after surgery may have a fluid collection (seroma), an infection or, rarely, a condition called breast implant-associated anaplastic large cell lymphoma. These need prompt assessment; you can read more on our BIA-ALCL page.
Any new lump, sudden swelling, redness or fever after breast implant surgery should be checked by a doctor promptly, rather than assumed to be capsular contracture.
What causes capsular contracture?
The exact cause of capsular contracture is not fully understood, but the leading explanation is a low-grade bacterial layer on the implant surface (biofilm) that keeps the surrounding tissue mildly inflamed, together with factors such as bleeding, radiotherapy and implant rupture.
Biofilm and subclinical infection
Small numbers of bacteria, often ones that normally live on the skin or in the breast ducts, can attach to an implant during surgery. Instead of causing an obvious infection, they may form a thin, protective film on the implant surface. This “subclinical” infection does not cause fever or redness, but it is thought to keep the capsule in a state of low-level inflammation, which encourages it to thicken and contract. Much of modern prevention is aimed at reducing this contamination.
Bleeding and fluid around the implant
A collection of blood (haematoma) or fluid (seroma) around the implant after surgery appears to increase the risk of contracture, probably by increasing inflammation and scarring.
Radiotherapy
Radiotherapy to the chest wall or breast changes the skin and underlying tissue, making it stiffer and less elastic. Implants placed in irradiated tissue, or irradiated after placement, have a considerably higher risk of capsular contracture.
Implant rupture and other factors
A ruptured silicone implant may provoke an inflammatory reaction that leads to contracture. Other factors that have been associated with a higher risk in some studies include smoking, the incision site, the implant surface and the position of the implant. In many women, no single cause is found.
Who is at higher risk of capsular contracture?
Capsular contracture is more likely after radiotherapy, after a haematoma or infection, after a previous contracture, and with implants placed above rather than beneath the chest muscle.
The main risk factors usually discussed are:
- Radiotherapy — probably the strongest single risk factor, particularly in women who have had implant reconstruction after breast cancer.
- Previous capsular contracture — a woman who has had one contracture is more likely to develop another.
- Haematoma, seroma or infection after the original operation.
- Implant position — many studies show lower rates when the implant sits partly or fully beneath the chest muscle compared with directly beneath the breast tissue.
- Smoking — affects blood supply and healing and has been linked to more complications overall.
- Implant rupture, especially of older silicone implants.
- Incision site — some studies report a higher risk with incisions around the areola, where the implant may pass through breast ducts that carry bacteria, than with an incision in the fold beneath the breast.
Implant surface has been debated for many years. Older studies suggested textured implants had lower contracture rates in some settings, but textured implants have been linked to BIA-ALCL, and many surgeons now prefer smooth or minimally textured implants. The choice of implant is a balance of risks that your surgeon should explain to you.

- Ribs
- Muscle cover
Can capsular contracture be prevented?
Capsular contracture cannot be prevented completely, but careful surgical technique aimed at reducing bacterial contamination and bleeding appears to lower the risk considerably.
Many plastic surgeons follow a set of measures, sometimes described as a “no-touch” approach, which includes:
- Antibiotics given into a vein shortly before surgery.
- Careful skin preparation and keeping the implant away from the skin as much as possible, for example using a funnel-type insertion device.
- Choosing an incision in the fold beneath the breast where appropriate, rather than around the nipple or through the armpit.
- Covering the nipples during surgery to reduce contamination from breast ducts.
- Rinsing the implant pocket with an antiseptic or antibiotic solution.
- Meticulous control of bleeding to reduce the risk of haematoma.
- Opening the implant only when it is ready to be inserted, and handling it as little as possible.
- Placing the implant partly or fully beneath the muscle where this suits the patient.
What you can do yourself is more limited, but it helps: stopping smoking well before surgery, following wound-care advice, reporting increasing swelling or bleeding early, and attending follow-up. Some surgeons advise antibiotics before certain dental or other procedures in the first months after surgery; practice varies, so ask your own surgeon.
Breast massage and implant “displacement exercises” were once widely recommended. There is no strong evidence that they prevent contracture with modern smooth implants, and advice varies between surgeons.
Can capsular contracture be treated without surgery?
There is no reliable non-surgical cure for established capsular contracture; some medications and therapies have been tried, but the evidence is limited and surgery remains the main treatment for grades III and IV.
Options that are sometimes discussed include:
- Leukotriene-receptor antagonists such as montelukast or zafirlukast, which are asthma medicines. Small studies suggest they may soften early contracture in some patients, but this use is off-label, the evidence is weak and the medicines can have side effects, including mood and sleep changes with montelukast. They should only be used after discussion with a doctor.
- Massage, ultrasound therapy and similar treatments, which have little good-quality evidence.
- Observation, which is entirely reasonable for grade I and II contracture that does not bother you.
“Closed capsulotomy”, in which the capsule was broken by squeezing the breast firmly from the outside, was used in the past. It is no longer recommended, because it can rupture the implant, cause bleeding and often fails, and implant manufacturers advise against it.
If your breast is firm but comfortable and you are happy with how it looks, you do not have to have treatment. The decision depends on your symptoms and wishes, not on the grade alone.
How is capsular contracture treated with surgery?
Surgery for capsular contracture usually involves either releasing the capsule (capsulotomy) or removing it (capsulectomy), most often combined with replacing the implant and sometimes moving it to a new pocket.
Capsulotomy
In an open capsulotomy, the surgeon makes cuts in the tight capsule from inside, allowing the pocket to expand so the implant can sit more naturally. It is a smaller operation, but because the capsule stays in place, the risk of the contracture returning may be higher in some situations.
Capsulectomy
In a capsulectomy, the thickened capsule is removed. A partial capsulectomy removes the part causing the problem; a total capsulectomy removes the whole capsule. Removing the diseased capsule creates a fresh surface for a new capsule to form, and many surgeons prefer it for significant contracture, although it is a larger operation with a slightly higher risk of bleeding.
En bloc capsulectomy
An en bloc capsulectomy removes the implant and its capsule together as one intact piece. It is mainly used when there is a ruptured silicone implant or suspected BIA-ALCL. For ordinary capsular contracture, a total capsulectomy is often enough, and en bloc removal is not always possible or necessary, for example when the capsule is very thin or attached to the ribs.
| Procedure | What is done | Often used for |
|---|---|---|
| Open capsulotomy | Capsule is cut and released, left in place | Milder contracture, thin capsule |
| Partial capsulectomy | Part of the capsule is removed | Localised thickening |
| Total capsulectomy | Whole capsule is removed | Thick, calcified or recurrent contracture |
| En bloc capsulectomy | Implant and capsule removed together | Silicone rupture, suspected BIA-ALCL |
The removed capsule is often sent to the laboratory for examination, especially if there is fluid or any unusual appearance. You can read more about the operation on our breast implant removal and exchange page.

Will I need a new implant or a new implant pocket?
In most capsular contracture operations the old implant is replaced with a new one, and the implant is often moved to a different pocket to lower the chance of the contracture coming back.
Implant exchange
Because bacteria may be living on the surface of the old implant, most surgeons recommend replacing it rather than putting the same implant back. This is also an opportunity to review size, shape and surface type.
Changing the pocket
If the implant was placed directly beneath the breast tissue, moving it beneath the chest muscle (or to a fresh pocket created between the capsule and the muscle, sometimes called a “neo-subpectoral” pocket) is a common strategy. The new pocket has not been exposed to the old capsule and biofilm. In some reconstructions the opposite move is made.
Support materials and fat grafting
For recurrent contracture, some surgeons use an acellular dermal matrix (ADM) or a similar biological or synthetic mesh to line or support the pocket. Some studies suggest this may lower recurrence, although evidence is still developing and these materials have their own risks and costs. Fat grafting, using your own fat to add a soft layer over the implant or to improve irradiated tissue, is another option used in selected cases.
Removing the implants altogether
Some women decide not to have implants again. The implants and capsules can be removed, and the breast reshaped with a lift or fat transfer if needed. This is a valid choice, and a surgeon should discuss it openly alongside replacement.
Capsular contracture after breast reconstruction and radiotherapy
Capsular contracture is considerably more common in women who have implant-based breast reconstruction and radiotherapy, and in many of them the most reliable long-term solution is to replace or support the implant with their own tissue.
Radiotherapy is an important part of breast cancer treatment for many women and should never be avoided for the sake of reconstruction. Its effects on the skin and chest wall develop over months and years, so a reconstructed breast that looks good at first may gradually become firm, high and tight.
The options after radiotherapy often include:
- Capsulectomy and implant exchange, sometimes with fat grafting or ADM. This can help, but the risk of recurrence is higher in irradiated tissue.
- Conversion to autologous reconstruction, where the implant is removed and the breast is rebuilt with your own tissue, for example with a DIEP flap from the lower abdomen. Your own tissue brings a new blood supply and is not affected by capsular contracture.
- Latissimus dorsi flap from the back, often combined with an implant, which places healthy, non-irradiated tissue around the implant.
- Fat grafting, which may soften irradiated skin and improve contour.
The best approach depends on your body, previous surgery, the condition of the skin and your wishes. More detail is available on our pages on reconstruction after radiotherapy and autologous reconstruction. Any decision about timing should be made together with your oncology team.
Can capsular contracture come back after surgery?
Yes, capsular contracture can come back after surgery, and the risk of recurrence is higher than the risk of a first contracture, particularly after radiotherapy or repeated operations.
Published recurrence rates vary widely because studies include different patients, implants and techniques. Measures that may lower recurrence include removing the diseased capsule, replacing the implant, moving it to a new pocket, strict anti-contamination technique, and in some cases ADM or fat grafting. Even so, no surgeon can guarantee that contracture will not return.
What is recovery like?
Recovery after capsulectomy and implant exchange is often similar to, or a little longer than, the original operation:
- Many patients go home the same day or after one night.
- Drains may be used for a few days after a capsulectomy.
- A supportive bra is usually worn for several weeks.
- Light daily activities are often possible within a week; heavier lifting and strenuous exercise are typically avoided for about four to six weeks.
- Swelling settles over several weeks, and the final shape may take a few months.
Long-term follow-up helps detect a recurrence early. If your breast starts to feel firmer again, it is worth having it checked rather than waiting.
How a plastic surgeon can help
A plastic surgeon can assess how severe your capsular contracture is, explain whether treatment is needed, and plan the operation that best balances shape, comfort and the risk of recurrence.
Dr. Fatih Kılıç is a plastic, reconstructive and aesthetic surgeon who treats implant problems after both cosmetic augmentation and breast reconstruction. An assessment usually includes:
- A history of your previous operations, implant type and any radiotherapy.
- An examination to grade the contracture and assess the skin and soft tissue.
- Review of existing ultrasound or MRI reports, and arranging imaging if implant rupture is suspected.
- A discussion of the options: observation, capsulotomy, capsulectomy, implant exchange, pocket change, fat grafting, conversion to your own tissue, or removal without replacement.
If you have had breast cancer, plans are made in coordination with your oncology team, who remain responsible for your cancer care and follow-up. For wider correction of shape and balance between the breasts, see our page on revision and symmetry.
Getting an opinion on capsular contracture from Germany, Bulgaria or the UK
If you live in Germany, Bulgaria or the UK and your implants have become firm, distorted or painful, you can share photographs, operation notes and any ultrasound or MRI reports online for an initial opinion from Dr. Fatih Kılıç on whether surgery may help and which approach could suit you. Istanbul is about 1 hour 15 minutes by air from Sofia and about 3 hours from major German airports, so assessment and surgery can be planned as a short, focused stay. Any sudden swelling, redness or new lump should first be checked by your own doctor at home. After treatment you receive a written summary for your doctor at home to support follow-up. See international patients or contact us.
Frequently asked questions
How do I know if I have capsular contracture?
The usual signs are a breast that feels increasingly firm or tight, an implant that looks rounder or sits higher, visible distortion and sometimes aching or pain. A plastic surgeon confirms it by examination and grades it from I to IV. Sudden swelling is different and should be checked promptly.
How common is capsular contracture?
Capsular contracture is one of the most common complications of breast implants, but most women do not develop significant contracture. Rates vary widely between studies and are considerably higher after radiotherapy. Your surgeon can explain your personal risk.
When does capsular contracture usually happen?
It is most often noticed within the first one to two years after implant surgery. However, it can develop many years later, sometimes after an injury, a rupture or radiotherapy.
Is capsular contracture dangerous?
Capsular contracture is not cancer and is not dangerous in itself. It affects comfort and appearance and can be painful in severe cases. Any new lump, sudden swelling or redness should still be checked by a doctor.
Can capsular contracture go away on its own?
Established capsular contracture rarely improves on its own. Mild grade I or II contracture often stays stable and may not need treatment. Grades III and IV usually require surgery if they are bothering you.
Does massage help capsular contracture?
There is no strong evidence that massage prevents or reverses capsular contracture with modern implants. Some surgeons still recommend it after surgery and others do not. Follow the advice of your own surgeon.
Can medication treat capsular contracture?
Asthma medicines such as montelukast or zafirlukast have been used off-label, and small studies suggest they may soften early contracture in some patients. The evidence is limited and these medicines can have side effects, so they should only be used after discussion with a doctor.
What is the difference between capsulotomy and capsulectomy?
In a capsulotomy the tight capsule is cut and released but left in place. In a capsulectomy the capsule is partly or completely removed. Capsulectomy is a larger operation but is often preferred for thick or recurrent contracture.
Do I need an en bloc capsulectomy for capsular contracture?
Not usually. En bloc capsulectomy, where the implant and capsule are removed together in one piece, is mainly used for ruptured silicone implants or suspected BIA-ALCL. For ordinary contracture a total capsulectomy is often sufficient.
Will my new implants get capsular contracture again?
Recurrence is possible and is more likely than a first contracture, especially after radiotherapy. Removing the capsule, using a new implant, changing the pocket and careful technique may reduce the risk, but no surgeon can guarantee it will not return.
What can I do after radiotherapy if my implant reconstruction becomes hard?
Options include capsulectomy with implant exchange, fat grafting, adding a latissimus dorsi flap, or replacing the implant with your own tissue such as a DIEP flap. Autologous tissue is not affected by capsular contracture. The right choice depends on your tissues, previous surgery and wishes.
How long is recovery after capsular contracture surgery?
Many patients return to light daily activities within about a week. Strenuous exercise and heavy lifting are usually avoided for around four to six weeks. Swelling settles over several weeks, and the final shape may take a few months.
