In short
- The capsule is normal. Every implant ends up surrounded by a layer of tissue the body forms; it is not in itself a complication.
- There are four distinct procedures —intact total, precise total, partial and en bloc— and since 2024 they have agreed definitions, precisely because they were being used as synonyms.
- 🚨 En bloc removal has one recognised indication only: implant-associated cancer, confirmed or suspected. Not for general symptoms, not in patients without symptoms and not as prevention.
- ⚠️ And it is not harmless: the consensus itself describes it as a long, complex operation capable of leaving the breast deformed.
- Removing more capsule is not free: the more raw surface is left, the more likely bleeding and seroma become.
- A breast that increases in size late on does call for investigation. It is the sign that implant-associated lymphoma is looked for by, and in Spain there is an official protocol for it.
- Nobody has shown that removing the capsule reduces the risk of developing that lymphoma later on.
“En bloc” does not mean more complete, or safer, or better done: it is a particular kind of capsulectomy with a narrow indication. It gets asked for a great deal by name, and the international consensus that pinned down the definitions in 2024 reserves it for one scenario alone: an implant-associated cancer, confirmed or suspected after the appropriate work-up.
This does not mean the capsule is left alone. It means there are four different ways of dealing with it and that the choice is made on what is found, not on which name sounds the most definitive.
This page sets out the technical side of breast implant removal.
What the capsule is
When any implant is placed, the body isolates it by forming a layer of fibrous tissue around it. It is the normal response to a foreign body and it happens to everybody. In most patients it is thin, flexible and gives no symptom at all.
What varies between one woman and another is:
- the thickness, which can range from a barely visible sheet to a hard layer;
- the firmness and the contraction, which is what produces capsular contracture when the tissue tightens and squeezes the implant;
- the calcifications, commoner the longer the implant has been in place;
- the contents, because sometimes fluid collects between the capsule and the implant.
🔑 The capsule is also the reason an explantation is not just “taking the implant out”. What is decided in theatre is what to do with it.
The four procedures
In June 2024 the Breast Surgery Collaborative Community —a coalition bringing together surgeons, patient associations, the American Society of Plastic Surgeons and The Aesthetic Society— published a consensus document with the definitions, because the same terms were being used for different things.
| Procedure | What it involves | When it is considered |
|---|---|---|
| Intact total capsulectomy | The whole capsule is removed in a single piece | A thick or calcified capsule that can be lifted off whole |
| Precise total capsulectomy | The whole capsule is removed, not necessarily in one piece | The same, when the capsule is stuck down and comes away in pieces |
| Partial capsulectomy | Part is removed and the rest left | A thin capsule with no findings, or areas stuck to structures it is better not to strip |
| En bloc removal | The capsule is removed with the implant inside it and a margin of healthy tissue around it | Only where there is implant-associated cancer, confirmed or suspected |
⚠️ The difference between “intact total” and “en bloc” is the one most often confused, and it is not a nicety: the first removes the whole capsule; the second also removes healthy tissue around it, which is what makes it cancer surgery and not surgery on the capsule.
Why “en bloc” is not the good version
It is the most important part of this page, because the opposite is what circulates.
The 2024 consensus establishes that en bloc removal is only indicated where there is an implant-associated cancer, confirmed or suspected after the appropriate medical work-up. And it adds three reasons that are worth reading in full:
- it is a long, complex and expensive procedure;
- it can leave significant deformities of the breast and it has complications of its own, among them bleeding and wound problems;
- it is not known that removing the capsule changes the risk of developing implant-associated lymphoma later on, and cases have been described that appeared even after a capsulectomy.
🚨 Translated into the conversation in consultation: asking for “en bloc” because it sounds more complete can add risk without adding benefit. What is worth asking is what is going to be done with the capsule and why, and that the answer should match the findings.
So when is the capsule removed?
When there is a reason, and the reasons are specific:
- Symptomatic capsular contracture, with hardening, pain or deformity.
- A thick or calcified capsule, which if left keeps the shape of the implant and can be felt.
- Rupture of the implant with silicone outside it, because the material stays inside the capsule.
- Late seroma, that is, the appearance of fluid months or years after the surgery. Here it is not a matter of appearance: it is the sign that calls for investigation.
- Suspected or confirmed implant-associated lymphoma, which is the indication for en bloc removal.
And there is a reason on the other side, which is also clinical: if the capsule is thin, healthy and very stuck to the chest wall, removing it completely can carry more risk than leaving it. It is the reason partial capsulectomy exists and is not a botched version of the total one.
Late seroma and why it calls for investigation
It is the warning sign most worth knowing about, and also the easiest to ignore because it does not hurt.
A breast that increases in size months or years after surgery, with no injury and no infection, has to be investigated. It is the commonest way breast implant-associated anaplastic large cell lymphoma presents, and in Spain there is an official protocol for detecting it, drawn up by the AEMPS advisory commission together with experts in Medical Oncology and Haematology and updated in 2024.
The figures, to put it in proportion. In its sixth follow-up report, published on 3 June 2026, the AEMPS reports that up to 2025 it had received 146 notifications of suspected cases, of which 111 have been confirmed.
⚠️ Neither alarmism nor denial. No health authority recommends removing implants preventively from women without symptoms. What is called for, without delay, is to seek advice about an increase in size appearing late on. The page on BIA-ALCL lymphoma sets it out in full.
What is done with what is removed
It is a very frequent question and it has two different answers.
The capsule. It is sent for pathology when there is a reason —late seroma, a suspicious finding during surgery, a very marked contracture. The report describes what is there: inflammation, calcification, the presence of silicone, abnormal cells. Confirming a tissue reaction is not the same as identifying the material of the implant, which is a different analysis and which in practice does not change the surgery.
The removed implants. Here they are not given to the patient, and the reason is a health one: an implant that has spent years inside the body is an item with biological contamination, and as such it follows the hospital’s waste route. It is not an administrative rule that can be got round by asking beforehand.
🔑 What is done, and it almost always answers the question behind the question: you are shown photographs of the state of the implants. Anyone who asks about their implants rarely wants the object — they want to see what state they were in: whether the gel had leaked, whether there were ruptures, whether the surface had changed. That is seen far better in a photograph from theatre than in a bag.
The added risks of a capsulectomy
Removing capsule is not neutral, and the consensus says so expressly. The risks grow with the extent of what is removed:
- Bleeding and haematoma. The more capsule is lifted off, the greater the raw surface.
- Post-operative seroma, for the same reason.
- Pneumothorax, uncommon but described, because of how close the capsule lies to the chest wall when it is very stuck down.
- Deformity of the breast, particularly when the removal takes breast tissue with it.
- Longer surgical and anaesthetic time, which in a patient with other health problems is no minor detail.
🔑 This list is exactly why a capsulectomy is tailored to the findings, and is not done beyond what is needed “just in case”.

Frequently asked questions
What is en bloc explantation and when is it needed?
It is removing the implant with the capsule intact around it and, in addition, a margin of healthy tissue. The 2024 international consensus reserves it for an implant-associated cancer, confirmed or suspected after the appropriate work-up. It is not indicated for general symptoms or in patients without symptoms.
Does the capsule always have to be removed when the implant is taken out?
No. It is removed when there is a reason: symptomatic contracture, a thick or calcified capsule, rupture with silicone outside the implant, late seroma or suspected lymphoma. If the capsule is thin and healthy, removing it completely can add risk without adding benefit.
What are the risks of a total or en bloc capsulectomy?
Bleeding and haematoma, seroma, pneumothorax —uncommon but described—, deformity of the breast and longer time in theatre and under anaesthesia. The risks increase with the amount of capsule removed, and that is the medical reason it is not done beyond what is needed.
Does removing the capsule protect me from BIA-ALCL lymphoma?
There is no evidence that it does. The 2024 consensus states expressly that it is not known whether capsulectomy changes the risk of developing that lymphoma in the future, and that cases have been described appearing after a capsulectomy.
What is a late seroma and why does it call for investigation?
It is a collection of fluid around the implant appearing months or years after surgery, with no blow or infection to explain it, and it is noticed as an increase in the size of the breast. It is the commonest way implant-associated lymphoma presents, which is why the Spanish protocol requires it to be investigated rather than simply drained.
Are the capsule and the removed implants analysed?
The capsule is sent for pathology when there is a clinical reason. The implants are clinical waste and follow the hospital’s route. If you want to keep them or see them, you have to ask before the operation. And on keeping them: here they are not handed over, because they are clinical items with biological contamination. What is usual is showing you photographs of the state they came out in, which is what really answers the question.
How much does a total capsulectomy lengthen the operation?
A good deal, and it depends above all on how stuck down the capsule is. It is one of the variables that most moves the time in theatre and, with it, the quotation.
I have been told “en bloc” is the best. Is that so?
Not as a rule. “En bloc” describes a technique with a specific cancer indication, not a standard of quality. What is worth asking in consultation is what is going to be done with the capsule and for what reason, and that the answer should match what has been found on examination and on the investigations.
