Common Problems After Breast Reduction Surgery

Dr Scott J Turner | Specialist Plastic Surgeon (FRACS) | Sydney

Every week in clinic I see women who’ve spent years carrying breasts that have ground down their posture, left deep bra-strap grooves on the shoulders, triggered persistent skin rashes under the breast fold, and effectively ruled out the kind of exercise they’d like to do. Reduction mammoplasty, or breast reduction to most patients, is one of the operations that genuinely changes the day-to-day of people dealing with all of that. It’s also, at the end of the day, surgery. General anaesthetic, incisions, tissue being moved around, weeks of healing. Complications happen, and you deserve a clear picture of what they look like before you sign a consent form. Here’s the short version. Most complications are minor and settle with time. Wound healing issues at the incision lines are what you’re most likely to bump into. The serious stuff, the kind that lands you back in theatre or in hospital for a second stay, sits in the low single-digit percentage range across the published literature.

I’m Dr Scott J Turner, Specialist Plastic Surgeon (FRACS), and I consult and operate at Bondi Junction and Manly in Sydney. What follows is a plain-language walk through the common complications after breast reduction. What they are. How often they happen. How we deal with them. And what to watch for during your recovery.

The Complication Rate in Context

A quick word on numbers before we get into specifics.

Go hunting through the literature and you’ll find complication rates for breast reduction ranging from about 2% up to around 20%, which is unhelpfully wide. The reason the range is so broad is that studies don’t agree on what actually counts as a complication. Some papers only record things that needed a return to theatre or a hospital readmission. Others count every minor wound redness and every patient who needed a dressing change. Different populations, different surgical techniques, different follow-up windows. So the honest answer to “how often do complications happen” is that it depends on what you’re counting and who’s doing the counting.

What the papers do agree on is this. When complications happen, most of them are minor. A patch of wound that’s slow to close. A small area of fat that doesn’t heal well. Temporary numbness. The sort of things that sit somewhere between “annoying” and “frustrating” rather than “serious”. The serious end of the spectrum, return to theatre, hospital readmission, meaningful intervention, is uncommon.

And your personal number shifts a lot depending on who you are. Smokers are at meaningfully higher risk of almost everything on the list below. Same for obesity, uncontrolled diabetes, very large reductions, and a handful of medical conditions that mess with blood supply or healing. On the other side of the coin, if you’re a non-smoker at a stable weight in otherwise good health, your personal risk profile is going to sit well below the averages you’ll read in any study.

In rough order of how commonly they show up:

Delayed Wound Healing

The most frequent issue I see after breast reduction. It turns up most often at the T-junction, the point where the vertical scar meets the horizontal scar in the inframammary fold. The blood supply to that corner is always the poorest of any point on the closure, purely because of geometry. Minor wound separation or slow healing at the T-junction is genuinely common.

Published numbers vary. One well-known series found some degree of T-junction breakdown in around 21% of patients. Most of what I see is minor: a small area that closes up with dressings, saline, and time. The bigger breakdowns are the ones that need active management, antibiotics, occasionally a minor procedure to tidy things up. It’s worse in smokers. Worse with very large reductions. Worse when the closure is under tension.

Bruising and Prolonged Swelling

Bruising and swelling aren’t complications. They’re part of having surgery. Everyone gets them, and for the first couple of weeks they usually look worse than they feel. What crosses into complication territory is bruising that’s unexpectedly severe, markedly worse on one side than the other, or that doesn’t seem to be settling on the timeline we’d expect. Same with swelling. Expected early. Worth a phone call if one side is significantly larger than the other after the first couple of weeks, or if it’s increasing rather than decreasing.

Severe bruising can hint at ongoing bleeding underneath. Persistent one-sided swelling is often a seroma, meaning a collection of tissue fluid. The smaller versions of both usually settle on their own. The bigger versions sometimes need draining, which is a straightforward in-clinic procedure in most cases. The recovery guide goes into what normal looks like day to day, and what doesn’t.

Haematoma

A haematoma is a collection of blood inside the breast tissue after surgery. It usually declares itself in the first 24 to 72 hours, and it’s the one complication that I think most about in the early recovery window. Published rates sit around 3 to 4%. The breast feels dramatically more swollen, firmer, and more painful than the other side.

This is one of the main reasons I keep patients in hospital overnight after breast reduction. Catching a haematoma early, when you’re still in a hospital bed, is relatively straightforward. Catching it at home a day later, when you might not know what you’re looking at, is harder. Treatment is a return to theatre to evacuate the collection and find the bleeding point. Results are generally good when it’s caught and dealt with promptly.

Infection

Uncommon after breast reduction. Published rates typically under 2 to 3%. Usually appears somewhere between days three and ten after surgery, with a warm, red, tender area around an incision, sometimes with discharge, sometimes with a fever.

Most infections I see respond to a course of oral antibiotics. The more serious ones need IV antibiotics and occasionally surgical drainage. Smokers, people with diabetes, people with a higher BMI, and patients who’ve had previous surgery in the same area are all at higher risk.

Seroma

A seroma is a collection of clear tissue fluid, most commonly turning up in the first two to three weeks after surgery. Published rates around 1%, though small seromas that resolve without anyone doing anything are probably more common than the data suggests.

The ones that matter clinically present as persistent one-sided swelling or a palpable fluid pocket. Treatment is aspiration, literally drawing the fluid off with a needle in the clinic. Occasionally we need to repeat this over a couple of visits until the fluid stops accumulating. Surgical drainage is rare.

Scarring

Scarring isn’t really a complication. It’s an inevitable part of the operation. Every breast reduction leaves scars. The question is how well they mature, and that depends on surgical technique, your individual healing, your genetics, and how you look after the scars during the first year.

The standard anchor pattern produces three scars: one around the areola, one running vertically from areola to fold, and one along the fold itself. For most patients the vertical and fold scars fade to something reasonably subtle over 12 to 18 months. Some patients develop thicker or more prominent scars despite everything being done correctly. Genetics plays a significant role here, and there isn’t a way to fully predict it.

Keloid and hypertrophic scars are the more troublesome end. These are more common in patients with darker skin tones or a family history of keloid formation, and they can stay raised and red for a long time. Silicone-based products, occasional corticosteroid injection, and consistent sun protection all help. Results vary.

Nipple Sensation Changes

Sensation changes in the nipple and the surrounding skin are expected after breast reduction. Almost every patient has some change, at least in the short term. For most it’s temporary, a period of altered or reduced sensation that recovers over months. Some patients have permanent changes, usually reduced sensation, occasionally altered or heightened.

How often permanent change happens depends on the size of the reduction and the technique used. Pedicle techniques that preserve the main nerve supply to the nipple typically have lower rates of permanent sensation change than free nipple graft techniques, where the nipple is detached and replaced, and sensation is usually lost permanently.

Breastfeeding Changes

Breast reduction can affect breastfeeding. Many women go on to breastfeed successfully after reduction surgery, but some find supply is reduced, and a smaller group find they can’t breastfeed on the operated side. It depends on the surgical technique and how much of the ductal system has been preserved. Pedicle techniques hold onto more breastfeeding function than free nipple graft techniques.

If future breastfeeding matters to you, please tell me at consultation. It’s not a reason to avoid the operation, but it does influence technique choice and it influences the conversation we need to have about realistic expectations.

Fat Necrosis

Areas of fat that lose their blood supply during surgery can form firm, sometimes tender lumps under the skin. Most resolve over months without anyone doing anything. Larger or persistently firm areas occasionally need a minor procedure to remove. Rates are higher in large-volume reductions and in smokers.

Worth knowing: fat necrosis lumps can be confused with breast lumps of other causes on examination, and they can also look unusual on imaging. If you end up needing a mammogram or ultrasound in the years after your reduction, mention to the radiologist that you’ve had the surgery. It saves a lot of unnecessary investigation.

Asymmetry After Surgery

Natural breasts aren’t usually a perfectly matching pair. That’s worth remembering before you judge your surgical result too harshly. Post-operatively, the two breasts heal at different rates, swelling settles unevenly, and small differences in size, shape, or nipple position are common in the first few months.

Clinically significant asymmetry that’s still bothering you once everything has settled may be worth revising. Most asymmetry, though, improves as swelling fully resolves and tissues mature. Revision rates for asymmetry specifically sit under 5% in most published data.

Need for Revision Surgery

Revision surgery after breast reduction is uncommon but possible. Reasons include persistent significant asymmetry, wound healing problems that leave poor scars, recurrent ptosis (the breasts dropping more than expected over time), fat necrosis that needs excision, and occasionally unhappiness with final volume.

Overall revision rates in the first year post-operatively are generally reported under 5%. Some patients end up having revision surgery years later for reasons that have nothing to do with the original operation, more to do with aging, weight change, or pregnancy.

Deep Vein Thrombosis

Clots forming in the deep veins of the legs are a risk of any major surgery. Breast reduction specifically isn’t high risk compared to longer abdominal or orthopaedic operations, but the risk isn’t zero. Rates are typically well under 1%. Prevention looks like early mobilisation, compression stockings during and after surgery, good hydration, and a proper risk assessment for anyone with additional risk factors.

Warning signs of a DVT: calf pain, swelling, or redness. Sudden chest pain or unexplained shortness of breath can be a pulmonary embolism, meaning the clot has moved to the lung, and that needs emergency assessment, not a call to the rooms.

Pulmonary Complications

General anaesthetic carries small risks related to breathing. Atelectasis (when small airways in the lungs partially collapse), pneumonia, and other respiratory issues are uncommon after breast reduction specifically. They’re more relevant in longer operations or patients with pre-existing lung disease.

Is Breast Reduction Surgery Safe?

Yes. For most patients. That’s the honest answer.

Breast reduction has been performed for decades, by thousands of surgeons across the world, with a substantial body of outcome data behind it. As surgeries go, the steps are well understood, the recovery is predictable, and the range of possible results is reasonably well defined. In the hands of an appropriately trained surgeon, on a suitable patient, it sits firmly in the “generally safe” category.

That said, safe does not mean risk-free, and I won’t pretend otherwise. Every general anaesthetic carries risk. Every operation involving incisions can bleed, get infected, or heal badly. Every procedure on breast tissue carries specific risks around nipple sensation, breastfeeding capacity, and how the final scars look. These things are real, and they deserve your attention.

What works in your favour? A few things. The operation is well refined, so surgeons are working from a solid playbook with predictable steps. Serious complications turn up uncommonly in the literature. Most complications that do occur are the kind that get managed in the clinic or with a short course of antibiotics. Long-term data on revision rates, patient-reported experience, and scar maturation is substantial and reasonably consistent across populations.

What works against you? Smoking, more than anything else. It significantly increases wound healing complications, infection rates, and fat necrosis. Obesity and poorly controlled diabetes both reduce healing capacity. Very large reductions carry higher complication rates than smaller ones, and the relationship isn’t linear, it’s worse than you’d expect. Previous chest surgery or radiation affects blood supply to the operated area. And a handful of medical conditions affecting circulation or healing will push your numbers up.

Where does that leave you? If you’re a non-smoker at a stable weight with otherwise good general health, your individual complication rate is likely to sit below the published averages. If you don’t fit that description, you’re not automatically ruled out. What it means is that we need to have a genuine conversation at your consultation about your specific risk profile, and about whether the likely benefit is worth the likely risk for you personally.

When to Get Problems Checked

Most complications are better managed caught early. Call the rooms straight away for any of:

Increasing pain: pain should decrease with time, not the other way around
Asymmetric swelling or bruising: markedly worse on one side can mean haematoma or seroma
Temperature over 38°C: possible infection
Red, warm, tender area around incisions: possible infection
Yellow or green discharge: possible infection
Wound edges separating: needs active management
Persistent one-sided swelling after other swelling has settled: possible seroma
Calf pain, swelling, or redness: possible DVT, needs urgent assessment
Sudden chest pain or breathlessness: possible pulmonary embolism, do not call us first, go to emergency

Early review is always better than late review. If something feels wrong, don’t sit on it overnight. Call.

Reducing Your Risk

Here’s the thing about risk factors: most of the ones that actually matter are within your control. Not all of them, but most. The things I ask patients to think about before surgery, in rough order of how much they matter:

Smoking. Stop. Vapes, cigarettes, nicotine patches, all of it. At least six weeks before surgery. Nicotine constricts blood vessels and interferes with wound healing at a cellular level. Every healing complication I’ve mentioned above gets worse in active smokers. I will tell you honestly if you can’t commit to stopping, we probably shouldn’t be operating.

Weight. Being at a stable weight around the time of surgery is associated with fewer complications. Major weight loss after a breast reduction can affect the shape and position of the breasts, and significant weight gain can do the same. Stable is what you’re aiming for.

Diabetes. Well-controlled diabetes doesn’t preclude surgery, but it needs to be optimised beforehand. Poorly controlled diabetes significantly raises complication rates, and that’s a conversation I have with your GP as part of planning.

Medications. Blood thinners, some anti-inflammatories, certain herbal supplements, all need managing around the time of surgery. We go through your full medication list at consultation and give you specific instructions for the weeks leading up to the date.

Follow the post-op instructions. Sounds obvious, but it matters. Wear the compression garment. Respect the activity restrictions. Show up to your follow-up appointments. Patients who follow post-op guidance have fewer complications than those who don’t.

Keep your expectations realistic. Patients who go in with a clear understanding of what surgery can and can’t do tend to cope better with the whole process, regardless of exactly how recovery unfolds. Unrealistic expectations are a major driver of dissatisfaction even when the surgery itself has gone without a hitch.

AHPRA Consultation Requirements

The AHPRA cosmetic surgery guidelines came into effect on 1 July 2023, and they include specific requirements around how consultations are run for cosmetic procedures. You’ll need a GP referral. A minimum of two consultations with me before surgery is booked. A psychological evaluation, depending on your circumstances. And a mandatory cooling-off period between your consent and the surgical date.

Use the process. Don’t try to shortcut it. The two consultations exist so that you have time between visits to think through questions, second-guess yourself, raise new concerns. Write things down. Come back with more questions at the second visit. Take the cooling-off period for what it is, a genuine pause to sit with a significant decision. This is surgery. You shouldn’t feel rushed.

Frequently Asked Questions

What is the most common problem after breast reduction surgery?

Delayed wound healing, by a long way. Most often at the T-junction, where the vertical incision meets the fold incision in the inframammary crease. Published studies report minor wound issues at this spot in up to around 21% of patients, though the majority are small and settle with dressings and time rather than needing anything surgical. Larger breakdowns that need active management are much less common. The T-junction is vulnerable because the blood supply to that corner point is naturally lower than anywhere else on the closure. Smoking, large reductions, and wound tension all increase the risk.

Is breast reduction surgery safe?

For most patients, yes. Breast reduction is one of the better-studied operations in plastic surgery, with decades of outcome data behind it. Serious complications are uncommon in the literature. Most complications that do happen are minor and manageable. That said, no surgery under general anaesthetic is risk-free. Wound healing issues, scar concerns, changes in nipple sensation, and changes to breastfeeding capacity are all recognised possibilities. Your individual risk depends on factors like smoking status, weight, diabetes, and how much tissue is being removed. Non-smokers at a stable weight in good general health typically sit below the published averages.

How common is infection after breast reduction?

Infection rates after breast reduction are typically under 2 to 3% in published series. Most cases respond to a course of oral antibiotics. More serious ones occasionally need IV antibiotics or surgical drainage. Infection usually shows up between days three and ten after surgery, with warmth, redness, tenderness around an incision, sometimes discharge, sometimes fever. Risk factors include smoking, obesity, diabetes, and previous surgery in the same area. Staying alert to the early signs and being seen quickly gives the best chance of a simple outcome.

Can breast reduction surgery affect breastfeeding?

Yes, it can, though many women still breastfeed successfully after reduction surgery. How much depends on the surgical technique used. Pedicle techniques preserve the connection between the nipple-areola complex and the underlying ductal system, which maintains more breastfeeding function than free nipple graft techniques, where breastfeeding is typically not possible. If future breastfeeding is important to you, raise it specifically at consultation. It influences the timing advice (most patients are advised to complete their family first) and the surgical approach we plan for.

What are the long-term risks of breast reduction?

Long-term considerations include ongoing scar changes (mostly improvement with time, occasionally thickening), permanent changes in nipple or breast sensation, reduced breastfeeding capacity, and the possibility of needing revision surgery years later for reasons related to aging, weight change, or pregnancy rather than anything wrong with the original operation. Long-term follow-up studies describe generally positive patient-reported experience, with many women continuing to report relief from the back, neck and shoulder symptoms that drove them to surgery in the first place. Long-term breast cancer surveillance continues as normal, and the procedure itself does not appear to increase breast cancer risk.

Consult with Dr Scott J Turner

Reading about risk is one thing. A proper consultation is where we actually sit down with your history, examine you, and work out what your individual risk profile looks like. That’s where informed consent really happens, not in a blog article.

I consult at both Sydney clinics, Bondi Junction in the Eastern Suburbs and Manly on the Northern Beaches. I also run consulting clinics in Brisbane, Canberra and Newcastle. You’ll need a GP referral before your first consultation, which is an AHPRA requirement and, frankly, a useful filter, because your GP is best placed to document your symptoms over time for both the clinical picture and any Medicare application.
