Breast implants - Complications 

Risks associated with breast implants 

Like any type of operation, surgery to fit breast implants is associated with a number of complications.

These may be related to the operation itself, or they may occur later as a result of a problem with the implants.

In some cases, additional surgery may be needed to treat problems that develop.

General risks of surgery

All forms of surgery carry some degree of risk. Complications that can affect anyone who has surgery include:

  • an adverse reaction to the anaesthetic
  • excessive bleeding
  • infection
  • blood clots

There are also complications specifically associated with breast implant surgery. Some of these are discussed below.

Capsular contracture

After having a breast implant, your body will create a capsule of fibrous scar tissue around the implant as part of the healing process. This is a natural reaction that occurs when any foreign object is surgically implanted into the body.

Over time, the scar tissue will begin to shrink. This shrinkage is known as capsular contraction. The rate and extent at which the shrinkage occurs varies from person to person. In some people, the capsule can tighten and squeeze the implant, making the breast feel hard. You may also experience pain and discomfort.

Capsular contracture is an unavoidable complication of breast implant surgery. Everyone who has breast implants will experience capsular contracture to some degree and it is likely further surgery to resolve the problem will be needed in the future.


A rupture is a split that occurs in the implant's casing. It can be caused if the implant's outer shell gets weaker over time, the implant is damaged during the operation, there is a flaw in the implant, or the breast is injured.

When implants were first developed, they had very thin walls and rupturing was a common problem. However, modern implants used in the UK since the 1990s rupture much less frequently.

If your implant ruptures, it is recommended you have it removed and replaced with a new one.

It is not always possible to tell if a breast implant has ruptured, but signs can include lumpiness, swelling, redness and tenderness in the breast.

If you have a saline (salt water) implant, any leakage from the implant should not cause you problems. As saline is a sterile salt-water solution, your body is able to safely absorb it. 

If you have silicone implants, the silicone that leaks out of a ruptured implant may cause problems, such as siliconomas or a gel bleed.

If your implant was fitted privately, you may need to pay for any special investigations needed to confirm a suspected implant rupture.


If you have a silicone breast implant that ruptures, the silicone may spread outside of the scar capsule and into your breast. This can lead to small lumps known as siliconomas developing.

Siliconomas can be tender to touch and they may need to be removed if they are causing significant pain. In rare cases, the silicone can spread to the muscles under your breast, your lymph nodes (glands) under your armpit, or around the nerves to your arm.

Gel bleed

Gel bleed occurs to some degree in all breast implants. It is where small molecules of silicone polymer separate from the surface of the implant and are taken up into the surrounding tissues or lymphatic system (the network of vessels that help the body fight infection found in several places around the body, including in the armpit).

If the silicone molecules get into the lymphatic system, they may cause your lymph nodes (glands) to become slightly swollen. This is usually a minor problem, although in some cases the enlarged lymph nodes can become uncomfortable.


After having breast implant surgery, fluid can build up around your implant. This is known as a seroma and is fairly common. Further surgery may be needed to drain away the fluid in severe cases, but most seromas resolve without needing to be drained.


After breast implant surgery, you will have some degree of scarring. In most cases the scarring is relatively mild.

However, in a few cases the scarring is more severe. For these women, their scars may be red, lumpy, thick or painful.

These symptoms should improve gradually and over time the scars will begin to fade. But in some cases it may take several years before there is a noticeable improvement.

Creasing and folds

Sometimes a breast implant can affect the appearance of the skin on your breast. For example, after your operation you may find your skin has creases, kinks, folds or ripples.

Creasing and folds tend to be more common in women who have very small breasts before having breast implant surgery.

Altered nipple sensation

After breast implant surgery, about one in seven women find their nipples are less sensitive or completely desensitised (have no sensation at all).

Alternatively, your nipples may be more sensitive after having breast implant surgery. Sometimes the nipples can become so sensitive they are painful. Increased sensitivity usually lasts for three to six months.

If your nipples are painful, speak to your GP or surgeon about it.

Breastfeeding problems

Having breast implants should not stop you breastfeeding, although some women will find they are not able to breastfeed after breast implants. You may also produce slightly less breast milk than you would without implants.

Your baby will not experience any side effects if you have implants and breastfeed.

Infection and bleeding

Infection and bleeding are relatively rare after breast implant surgery. However, if you are having an implant fitted for breast reconstruction after a mastectomy (breast removal), you may have a greater risk of infection and bleeding.

Most infections can be treated using antibiotics. But if your breast becomes severely infected, you may need to have the implant removed to prevent further complications developing. You should be able to have the implant reinserted after the infection has cleared up.

However, it is important the implant is not reinserted too soon, as this can increase the risk of infection. Waiting a few months after the implant was removed is usually recommended.

Some research suggests your risk of infection and bleeding may be increased if you smoke because your wounds will take longer to heal. Your surgeon may recommend not smoking before your operation to reduce the risk of developing complications.


All types of breast implants are associated with a slightly increased risk of a very rare form of cancer called anaplastic large cell lymphoma (ALCL). However, it is not clear if the implants themselves directly cause this condition, and the overall risk is still extremely small.

In the US, figures from the National Cancer Institute state only around 1 in every 500,000 women is diagnosed with ALCL each year, and only around 3 in every 100 million are diagnosed with ALCL in the breast.

Breast cancer

There is strong scientific evidence to suggest having breast implants will not increase your risk of developing breast cancer, but it is still important for women with breast implants to attend breast screening appointments when invited.

Breast implants can affect breast screening as it may be more difficult to interpret the mammograms of women who have implants fitted. You should tell the healthcare professional taking the scan you have implants so they can ensure the best possible images are taken. Having a mammogram is unlikely to cause rupture of an implant unless it is already damaged.

If you have breast implants and develop breast cancer, your chances of making a full recovery will not be affected, but it is likely you would need to have your implants removed during the course of your treatment.

Silicone implant safety concerns

In recent years the safety of silicone breast implants has been debated. A small number of women have reported serious complications after silicone gel breast implant surgery. These complications include:

  • muscle spasms and pain
  • swollen and painful joints
  • rashes
  • changes in eye and saliva fluid
  • hair loss

It was thought these complications may have occurred as a result of silicone gel leakage that spread to other parts of the body.

In response to these concerns, the Department of Health set up an independent review group to investigate the safety of silicone implants. The group found no scientific evidence to support the relationship between silicone implants and illness in women.

However, in March 2010 the Medicines and Healthcare Products Regulatory Agency (MHRA) advised surgeons not to use certain implants produced by a company called Poly Implant Prothese (PIP). These implants are filled with a type of silicone gel that has not been approved.

As yet there is no evidence to suggest the gel inside them is harmful. However, speak to your GP or the clinic where the implants were fitted if you have these gel implants and have any concerns.

I have had my breast implants for 15years and I am having some issues. Mine are saline....they really should have been replaced 5 years ago. My NHS doctor has said replacements are not covered which is fine. I have seen though that removals are covered by NHS. Does anyone have any experience of the removal on NHS then replacement privately. Is there a waiting period between removal and replacement surgeries? Or is it advisable to just have private replacement surgery and is there any further cost for the old removal if the surgeon is doing the replacement? Some advice would be fab :)

The procedure of breast enlargement surgery is very simple as the surgeon implant behind the natural breast tissue as it helps in increasing the size of the breast. The surgery only takes 2-3 hours and general anesthesia have been used before performing surgery. After having surgery patient has to suffer some swelling and soreness for some days but most of the patients recover within 4-5 days. It is instructed to wear a support bra the stitches will also be removed within a week. Most of the people think that breast enlargement surgery increases the risk of breast cancer, and it also affects your ability to breast feed but no scientific evidence has yet proven this. Breast enlargement surgery helps in adding volume and contours the breast that lacks fullness and shape. Breast enlargement surgery is performed by plastic surgeons but it is very important that you may select and experienced, well trained and professional surgeon.

I had implants fitted by harley medical nearly 4 years ago . Last year I found out they were pip ones and both ruptured !! It took me 6 mnths of hassle , chasing surgeon round the country and endless waiting on the phone . I finally had them replaced july 2012 . The operation was free but they didnt pay ANY expenses . I also paid £300 for STRONGER ones . Ive never been happy with shape of left one and now it is mishapen and hard . I rang harley , had to then ring pip helpline (they are NOT pip ones now ) .They said surgeon does not practice anywhere near me and Id have to go to harley st London to see him . Further surgery would not be free . I was pleased with the first implants if they hadnt fitted sub standard ones I would not have had to have them replaced !!! Im going to my gp to see if he can help as he was kind and sent me for nhs scan last year . My point to harley is the second operation was because THEY fitted the wrong ones in the first place . Im crying with worry , They look worse now than before I ever had implants . The first ones were great , but unfortunately pip ones . Do others think i have a point that harley should pay again ?

I had bilateral NHS breast implants at Mount Vernon in 1987. They had been in place for over 25 years with only 1 hospital follow up consultation. I wasn't aware that I had developed capsular contraction in the L.breast and routine mamograms had also failed to indicate problems. (I now know that only certain MRI scans will conclusively indicate the presence of leaked silicone) but I certainly had all the symptoms of Fibromyalgia from about 1996. I had an acromeoplasty and excision of L.shoulder blade in 2007 - probably caused by the wastage of the pec muscle that was 'melted' by leaked silicone. Despite surgery, my fibro symptoms worsened. Then, in the summer 2011, I thought I'd found cancer. A biopsy confirmed silicone leakage in the R.breast. Bi-lateral explantation followed in September 2011 but the L.implant breached. My condition deteriorated post-op and I was told I was a 'mystery.' Antibiotics were having no impact. Over the following 8wks the tissue in L.breast became necrotic and most of it was ultimately removed at the end of Nov 2011 after watching it 'die' for 8 agonising weeks. Exactly the same is now happening to the r.breast, only this time the leaked silicone that should have been a straightforward removal in Feb 2012 has now migrated to the tubes in the mammary gland as well as the nipple, muscle tissue and armpit. Ironically I had asked for a bilateral mastectomy in the first instance but I keep being told it is better to leave well alone.This is a living nightmare and my body clearly does not want this evil toxic substance any longer ! I have private medical insurance but treatment is denied because my implants, although done on the NHS, were not related to cancer. All complications since the explantation are also regarded as related to cosmetic not medical needs. Yet although I am not entitled to any NHS counselling, I'll be offered reconstruction the same as any other cancer patient. It all seems very unfair and frustrating - Help !

Great thread. @Joanm- I am in the exact same position- I had NHS implants put in 5 years ago when I was 25 (after a big battle to get them!) but one of them never felt right and I just ignored it and continued my daily exercise regime- running mainly. Anyway I got an infection last year in the same boob and my breast swole up really badly- it was never fully explained to me at the docs but she gave me antibiotics and the swelling went down. The surgeon sent me away as well. After 6 months I asked to see surgeon again, did a number of MRI scans and they finally agreed it is capsular contracture and to re-operate and replace the implant. The operation is going to be tomorrow and while I am pleased I'm scared in case the other one looks deformed on some level. Any feedback or speculation would be most welcome! Thanks!

I also had implants on nhs 15 years ago and had one check up 2 weeks later I had no problems till about 8 years ago I stepped off the side and the worst pain ever shot through my breast I called nhs direct and they advised me to go to casualty when I got there my breast was swollen red and hot to touch and the slightest movement caused pain I was examined by a doctor who said I had an infection in the muscle behind the implant I was given antibiotics which cleared the swelling ,pain and redness ever since my breast has looked lower than the other I haven't been back to the doctors as I don't have any other symtons other than it looking lower no pain I now am concerned that my breast had ruptured as I do always feel tired but put that down to being a mum of 3 and working I would welcome any advice thanks

I had breast implants on the NHS 15 years ago. Because of all the worrying press over PIP,
I contacted the hospital. i got an appointment and was assured that mine are not PIP, I asked if I could have a scan anyway because I had them put in so long ago. I just wanted confirmation that they are fine.I had a scan and was shocked to be told they are ruptured,
I have never had any problems with my breasts, no lumps or pain so would not even have known if I hadn't made contact. I have however had other health problems over the last 5 years which i'm now wondering if they could be the result of leaking silicone. When I had my implants i recieved 2 follow up appointments after year 1 and year 2. since then i have never been contacted by the nhs for any sort of after care or scan. Am i the only patient who didn't recieve any further appointment, this is for 13years. I was not unduly worried because I thought if an implant ruptured I would have know, so if my breasts had changed or hurt i would have gone to my GP for a referal. I am now thinking that surely the nhs know that they can rupture without obvious symptoms and so it should surely be their responsibility to continue to care for their patients or call them in for a scan every few years to check the condition of them or at least make patients aware that they can rupture and you wouldn't even know it so you could book a scan yourself every few years. Please let me know if you have had implants for a considerable length of time with or without any follow up appointments. thanks

I had saline breast implants about 8 years ago. I am now having problems with them, lumpy and painful under my arms. Does anyone know if my GP can refer me on the NHS to get them checked out or do I have to go private again? I know if I have to have them replaced I'll have to pay but not sure if I'll have to pay for a scan.

Any help would be appreciated.

Went to Transform to check if my implants were PIP they weren't. However I discovered that I had a ruptured implant. Now Transform say I am not covered for the cheap removal that is granted to PIP implants and they have reneged on the fee they were going to charge me and now want to inflate the price for removal. I now don't know what to do. Does anyone know your rights if your implant ruptures, I don't expect them to replace them for free, but I had the surgery because I was told I would have a lifetime guarantee that if anything went wrong they would remove the implants free. Now Transform are saying this has never been a part of their guarantee. Can anyone help with advice on what to do?

These are things that need to be spelt out clearly and carefully prior to surgery. However because this is an industry that is primarily profit-oriented, it will tend to only appear in the small print. Plus, most women who are seeking breast augmentation are so highly motivated that it is unlikely there will give this musch thought. Lately there has been further reason for a pause for thought as seen in this short article:

Will the NHS remove and replace my breast implants?

If you develop problems with your breast implants, you can usually have them removed on the NHS.

However, it is unlikely the NHS will replace the implants unless the original operation to fit them was carried out on the NHS.

If your implants were fitted privately, you may need to pay to have them replaced.
