Breast implant exchange carries the general risks of any operation, including bleeding, infection, blood clots and anaesthetic complications, plus implant-specific risks such as capsular contracture, implant malposition, rippling, altered nipple sensation and the need for further surgery. Because revision involves previously operated tissue, some risks are higher than after a first augmentation, so careful planning matters.
Why revision carries extra considerations
Every previous operation leaves scar tissue and changes the blood supply and thickness of the breast tissues. The old capsule may be thickened or calcified, the pocket may be stretched, and skin may be thinner. This makes revision technically more demanding and results a little less predictable than a first operation. Knowing this in advance helps you weigh up the benefits and risks realistically.
General surgical risks
- Bleeding (haematoma): a collection of blood around the implant, most likely in the first day or two. It may need a return to theatre. Stopping certain medicines and supplements beforehand, as advised, reduces the risk.
- Infection: may cause redness, heat, fever or discharge. Antibiotics and careful sterile technique reduce the risk; an infected implant sometimes has to be removed until healing is complete.
- Blood clots (VTE): deep vein thrombosis or pulmonary embolism. Early walking, compression stockings and, for some patients, blood-thinning injections help reduce this risk.
- Anaesthetic risks: including nausea and, rarely, more serious reactions. You will meet your consultant anaesthetist before surgery to discuss your health.
- Wound healing problems: slow healing or wound breakdown, more common in smokers or where an uplift is combined.
Implant-specific risks
- Capsular contracture: the scar tissue around the new implant tightens, causing firmness, distortion or pain. It can recur after revision.
- Malposition: the implant sits too high, too low or too far to the side, including bottoming out or a double bubble.
- Rippling and palpability: visible or palpable implant edges, more likely with thin tissue.
- Seroma: a collection of fluid around the implant, sometimes needing drainage.
- Altered sensation: numbness or increased sensitivity of the nipple or breast skin, usually temporary but occasionally long-term.
- Asymmetry: some difference between the two sides is common and may persist.
- Further surgery: implants are not lifetime devices, and more surgery may be needed in future.
BIA-ALCL and breast implant illness
Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare type of lymphoma that develops in the fluid or scar tissue around an implant and has been linked mainly to textured implants. It usually presents as a swelling of one breast, often years after surgery, and is treated by removing the implant and capsule. Some people also report a range of symptoms they attribute to their implants, often called breast implant illness. Mr Nassab will discuss both openly at consultation, including your implant type and any concerns you have.
How risks are reduced
Careful assessment, including previous operation notes and a scan where appropriate, allows problems such as rupture or a thick capsule to be anticipated. Choosing an implant size that suits your tissues, meticulous technique, operating in a CQC-registered hospital and structured aftercare all contribute to safety. Stopping smoking, reaching a stable weight and optimising any medical conditions before surgery make a real difference.
Normal after surgery versus a concern
Tightness, aching, bruising, mild swelling and some difference between the two sides are expected in the early weeks. Contact the surgical team urgently if one breast swells rapidly or becomes tense and very painful. Contact the team the same day if you develop fever, spreading redness or wound discharge. For calf pain or one-sided leg swelling, seek same-day assessment through your GP or NHS 111; for chest pain or breathlessness, call 999.
Late changes to report
Months or years after surgery, report any new swelling, lump, hardening, change in shape or persistent pain. These do not necessarily mean something serious, but they should be assessed rather than ignored. If you have silicone implants, a scan may be recommended to check for silent rupture when symptoms arise. Keep a record of your implant make, size and serial numbers, which are listed on your implant card, so that any future surgeon has the information they need. Cosmetic surgery is only offered to adults aged 18 and over.
Frequently Asked Questions
Is implant exchange riskier than a first augmentation?
Some risks are higher because of scar tissue and previous surgery, but careful planning helps keep them as low as possible.
Can capsular contracture come back after replacement?
Yes. It can recur, although removing the capsule and changing the pocket may reduce the chance.
Should textured implants be replaced because of BIA-ALCL?
Current UK guidance does not advise removing textured implants in people without symptoms. Discuss your individual situation at consultation.
Are drains needed?
Drains are sometimes used after capsule removal or extensive revision and are usually removed within a day or two.
