Breast Reduction Risks: Scars, Nipple Circulation, Sensation and Breastfeeding

Breast reduction is widely performed and often brings relief, but it involves trade-offs. Understanding them supports informed consent.

General risks

• Bleeding, infection and wound-healing problems
• Reactions to anaesthesia
• Blood clots

Risks specific to reduction

• Scarring: visible, widened or thickened scars, sometimes lasting
• Nipple and areola circulation: partial or, rarely, complete loss of blood supply, which is more likely in large reductions and smokers
• Sensation changes: reduced or lost nipple and breast sensation, which may be permanent
• Breastfeeding: milk production may be reduced or lost, particularly with large reductions or nipple grafts
• Asymmetry in size, shape or nipple position
• Fat necrosis, causing firm lumps
• Skin and wound breakdown, particularly at scar junctions
• Regrowth or changes with weight gain, hormones or pregnancy
• Further surgery

Risk factors

Smoking, higher body weight, large resections, diabetes and other conditions affecting healing can raise risk.

Blood supply needs close attention

Moving the nipple and removing tissue changes the blood supply to skin, fat and the nipple-areola complex. A surgeon will assess this during and after surgery, but compromised circulation can still occur. Increasing pain, unusual coldness, darkening, marked paleness or a worsening wound needs prompt review.

General health risks still apply

A preoperative assessment considers anaesthesia, blood clots, bleeding, medicines and medical conditions as well as the breast operation itself. Tell the team about prior clots, sleep apnoea, allergies, supplements and nicotine in all forms. Follow instructions about fasting and prevention of clots.

If further treatment is needed

Dressings, antibiotics, drainage, scar treatment or a further operation may be needed if healing does not follow the expected course. This can extend time away from work and alter the final shape. Ask how the team manages common complications and who to contact outside normal hours.

Personal plans matter

Before consenting, discuss pregnancy, breastfeeding, major weight change and your priorities around scars and sensation. There may be no option without trade-offs. The most suitable plan is one that reflects your health and goals, not simply the smallest scar or largest possible reduction.

Reducing risk

• Stop smoking before and after surgery
• Reach a stable, healthy weight
• Follow aftercare advice
• Choose an experienced surgeon

Breast screening

Scars and tissue changes can affect mammograms. Tell the imaging team about your surgery.

Questions to ask

• What are my specific risks?
• How likely is a nipple graft?
• What is the chance I could still breastfeed?
