Is only one breast treated?
Yes, unilateral reduction means reducing one breast.
If the plan includes a lift or another procedure on the opposite breast, that is additional surgery and should be explained separately.
Breast & Chest
Unilateral Breast Reduction for Asymmetry
Unilateral breast reduction removes tissue and skin from the larger breast to bring its size and shape closer to the other breast.
Will both breasts match?
The aim is a closer balance, not an exact match.
Differences in breast width, nipple position, skin and chest-wall shape can remain.
Does it leave scars?
Yes. Reduction requires permanent incisions.
The scar pattern depends on how much tissue and skin need to be removed and how the nipple is repositioned.
01 · Overview
Understanding reduction on one side
A reduction removes breast tissue, fat and excess skin. The surgeon reshapes the remaining breast and may reposition the nipple and areola. For unilateral reduction, this work is performed on the larger side. [1]
This differs from a bilateral reduction, which reduces both breasts, and from a breast lift, which mainly addresses sagging rather than size. Matching one breast to the other requires considering volume, shape, nipple height and the way each breast sits on the chest. [2]
Your consultation should explore how long the difference has been present, whether it is changing and what matters most to you. A new size change, lump, discharge or skin change needs medical evaluation before cosmetic planning.

Can one-sided reduction address nipple height too?
Often, the nipple and areola can be repositioned as the larger breast is reshaped. Differences in the untreated breast or chest wall may still limit how closely the sides align.
Does the smaller breast need surgery?
Not necessarily. Leaving it untreated may suit your goals. If closer shape balance would require a procedure on that side, ask what improvement it might add and what extra scars, risks and recovery it would involve.
02 · Concerns & Goals
What you may want to change
Breasts naturally differ. If that difference affects your comfort, clothing or confidence, you can discuss whether reducing one side fits your goals.
Uneven breast volume
One breast may fill a bra cup more than the other or make fitted clothing feel uneven.
Heaviness on one side
The larger breast may contribute to pulling, strap pressure or irritation. Reduction may help, but discomfort can have other causes.
Different shape or position
The larger breast may hang lower or have a different nipple position. Volume reduction alone may not address every difference.
Feeling self-conscious
You may want a less noticeable difference without changing the breast you already feel comfortable with.
03 · Options
How the approaches differ
These approaches are not interchangeable. Your surgeon will recommend a plan based on the size difference, skin, nipple position and blood supply.
Vertical-scar reduction
Reshapes the breast through incisions around the areola and down to the breast crease.
How it worksThe surgeon removes tissue and skin, reshapes the breast and repositions the nipple when needed.
May suitMay suit selected breasts where this pattern allows enough reduction and skin tightening.
Main tradeoffLeaves a lollipop-shaped scar and may not address substantial excess skin as well as a wider incision pattern.
Anchor-pattern reduction
Adds an incision along the breast crease.
How it worksThe additional incision allows removal of more excess skin and broader reshaping.
May suitMay suit a larger reduction or greater sagging on the treated side.
Main tradeoffCreates a longer scar, including a junction where wound healing can be slower.
Liposuction-only reduction
Removes fat through small incisions in carefully selected cases.
How it worksLiposuction reduces fatty volume without removing excess skin or directly lifting the nipple.
May suitMay suit a modest difference when the larger breast has enough fatty tissue and good skin elasticity.
Main tradeoffOffers limited control over glandular tissue, sagging and nipple position.
Reduction with free nipple graft
An uncommon approach for selected very large reductions.
How it worksThe nipple and areola are detached and placed back as a graft rather than kept attached to supporting tissue.
May suitMay be considered when the surgeon judges that an attached-nipple approach would not be safe.
Main tradeoffPrevents breastfeeding from that nipple and can cause permanent loss of sensation, pigment changes or graft loss.
The incision pattern and the method used to preserve nipple blood supply are separate parts of planning. Ask your surgeon to explain both for the breast being treated. [1] [2].
Can I choose an exact cup size?
Cup sizes vary between bra brands and cannot reliably define a surgical result. Discuss proportions, clothing fit and the amount of difference you hope to reduce instead.
Could a lift alone be enough?
A lift may help if position is the main difference, but it does not substantially reduce volume. If the breast is both larger and lower, a reduction may address both concerns.
04 · Results
What may improve and what may remain
Closer balance
Reducing the larger side may make the difference less noticeable.
- Exact symmetry is not realistic.
- Breast width, chest-wall shape and the untreated breast can limit the match.
Comfort and clothing
A lighter breast may improve fit and reduce some one-sided discomfort.
- Pain relief is not guaranteed.
- Bra fit is best reassessed after swelling and shape have settled.
Changes over time
The result continues to evolve after early recovery.
- Scars usually soften and fade but remain permanent.
- Pregnancy, weight changes and aging can affect the two breasts differently.
Swelling can temporarily exaggerate unevenness. Final shape takes months to assess, and further surgery may sometimes be considered. [1]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery depends on the amount of reduction, incision pattern and your health. The treated breast may look and feel different from the untreated side while it heals. Follow your surgical team's instructions.
Step 1 · Day of surgery
Treatment day
Dressings and a support garment may be placed. A drain is sometimes used. If you go home the same day, arrange transportation and help from a responsible adult.
Step 2 · First several days
Early healing
Soreness, swelling, bruising and tightness are common. Your team will explain wound care, medicines, sleeping position and any drain care.
Step 3 · Following weeks
Gradual return
Activity increases as the incisions heal and your surgeon clears you. Returning to work does not mean the breast is fully healed.
Step 4 · Following months
Settling and scar care
Shape, sensation and scars continue to change. Ask when scar treatments are appropriate and when the balance between breasts can be meaningfully assessed.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
Desk workPlanning context: Some people return within about one to two weeks; others need longer. [1]What affects it: Pain, fatigue, wound healing and commuting can affect timing.
DrivingPlanning context: Resume only when cleared and able to steer and brake safely without impairing medicines.What affects it: Chest discomfort and restricted arm movement may interfere with control.
Lifting and exercisePlanning context: Strenuous activity commonly remains restricted for several weeks. [1]What affects it: Heavy lifting and chest strain can stress healing incisions.
Bathing and swimmingPlanning context: Ask separately when showering and soaking are allowed.What affects it: Open incisions or drains can delay immersion in water.
These are planning guides, not personal clearance. Your team should tailor restrictions to your operation, job and healing.
Before your procedure
- Discuss your goals and whether the smaller breast will remain untreated.
- Share prior breast surgery, radiation, imaging results and any recent breast changes.
- Review medicines and supplements; change them only as directed.
- Discuss nicotine use and the team's requirements for stopping before and after surgery.
- Ask whether breast imaging or other testing is needed before surgery.
- Arrange transportation, early help at home and time away from lifting or strenuous work.
Should I use compresses for swelling?
Ask your surgical team whether compresses are appropriate and exactly how to use them.
Why might the treated breast look too high or firm at first?
Swelling and reshaping can temporarily change its position and firmness. Attend follow-up visits rather than judging the match early. Sudden swelling, severe pain or a rapid change needs prompt assessment.
06 · Safety
Risks and what your clinician assesses
Temporary soreness, bruising, swelling, tightness and altered nipple or skin sensation are common. Their intensity and duration vary; worsening or unexpected symptoms should be discussed with your team.
Bleeding or fluid collection
Blood or fluid can collect in the breast and may require drainage or another procedure.
Infection or delayed healing
Incisions can become infected or separate. Some areas may need prolonged wound care.
Blood-supply problems
Fat, skin or nipple tissue can lose blood supply, causing firm areas, tissue loss or the need for additional treatment.
Sensation and breastfeeding changes
Nipple or breast sensation may change permanently. Milk production and breastfeeding from the treated breast may be reduced or lost.
Scars or remaining unevenness
Scars may widen or thicken, and differences in size, shape or nipple position may remain. Revision surgery has its own risks.
Anesthesia and blood clots
Anesthesia reactions and clots in the legs or lungs are possible and can be serious.
Discuss these risks and your individual health history with your surgeon. [3]
What your clinician assesses
- Breast size, skin quality, nipple position and chest-wall differences
- Breast health, previous treatment and imaging needs
- Medical conditions, nicotine use and healing or clotting risks
- Goals, future pregnancy plans and acceptance of scars or remaining asymmetry

08 · Questions
Common questions
Can insurance cover reduction on only one side?
Possibly. Coverage depends on the reason for surgery, symptoms, documentation and your policy. Cosmetic asymmetry alone may not qualify. Ask about authorization and your expected share before scheduling.
Can I breastfeed afterward?
It may be possible, but milk supply from the treated breast can be reduced or lost. The untreated breast may still produce milk, though adequate supply cannot be promised. Discuss future feeding goals before choosing a technique.
What if I plan to become pregnant?
Pregnancy and breastfeeding can change breast size and balance. Your surgeon can help you weigh having surgery now against waiting until these changes have settled.
Will I still need breast screening?
Yes. Continue screening based on your age and risk. Tell your imaging team which breast was reduced and when, because surgery can change how tissue looks on imaging.
