What is breast asymmetry correction?
It is the surgery that evens out a visible difference between the two breasts: in size, in shape, in position or height, or in the size and position of the areola and nipple. Almost no woman has perfectly identical breasts —mild asymmetry is normal and needs no surgery—; the procedure is considered when the difference is noticeable enough to affect clothing, the balance of the silhouette, or how the patient sees herself.
Asymmetry can have several origins, and the plan depends on them: differences present since development in adolescence (including tuberous breasts or one-sided hypoplasia), changes after pregnancy and breastfeeding, variation from weight loss, or asymmetry left after previous breast surgery. It is not a single procedure with one solution: it is a symmetry problem solved by combining the tools of breast surgery according to which breast has excess, which lacks volume, and at what height each one sits.
Techniques used by Dr. Arístides Arellano
There is no standard technique for asymmetry, because every case combines a volume problem with a position problem. The plan is defined at the assessment, measuring each breast separately and deciding what to do on each side:
- Differently sized or profiled implants on each breast: when the difference is mostly volume, a larger or more projected implant —or a different profile on each side— is placed in the smaller breast to match them. It is a variant of breast augmentation applied asymmetrically.
- Fat grafting (the patient’s own fat): for mild or moderate volume asymmetry, fat is harvested from another area by liposuction and grafted into the smaller breast. It avoids implants when the difference is small and helps refine the contour; its suitability depends on the patient’s fat reserves.
- Augmentation on one side and a lift (mastopexy) on the other: when, besides volume, the nipple height or the droop of the breast differs, an augmentation on one side can be combined with a breast lift on the other, to match both size and position.
- Reduction of the larger side: if one breast is markedly larger, instead of enlarging the smaller one the larger can be reduced with a breast reduction of the dominant side, balancing toward the smaller breast.
- Tuberous breast correction: a specific technique for the developmental asymmetry in which the breast base is narrow and the areola protrudes (tuberous or constricted breast), which usually requires releasing the tissue, reshaping the base and, often, an implant.
- Areola and nipple correction: when the asymmetry lies in the nipple-areola complex —different diameter or different height—, its size or position is adjusted, either on its own or within a broader plan.
- Revision correction: for patients left with asymmetry after previous breast surgery —here or elsewhere—. It is technically more demanding because of scar tissue and prior planning, and it starts from a detailed study of what was done before.
How is it performed?
Surgery is performed under general anaesthesia in a hospital operating room, and its length varies —approximately 1.5 to 3 hours— depending on how many techniques are combined and whether one or both breasts are operated on. Planning is what sets this surgery apart: the patient is marked while standing, before anaesthesia, measuring each breast separately, because the reference is not an abstract ideal but the balance between the two sides. It is generally an outpatient or short-stay procedure, with a surgical bra placed at the end.
All surgery carries risk and requires a prior medical assessment. Results may vary according to each patient, their anatomy and their individual healing process.
Who is a good candidate?
A candidate for breast asymmetry correction has a noticeable difference between the two breasts and is in good general health:
- A visible size difference between one breast and the other, noticeable in clothing or when choosing a bra.
- A difference in shape, projection or droop between the two sides.
- A tuberous or constricted breast, on one or both sides, with a narrow base and prominent areola.
- Asymmetry of the areola or nipple (different size or different height).
- Asymmetry that persists after previous breast surgery.
- Complete breast development; for adolescent asymmetry, the assessment considers whether it is better to wait until development is finished.
- Realistic expectations: the goal is much greater, natural-looking symmetry, not two mathematically identical breasts, which do not exist even naturally.
Recommended post-surgical treatments
To support a more comfortable recovery and reduce swelling, Dr. Arístides may recommend, depending on the case, manual lymphatic drainage and hyperbaric chamber sessions, along with wearing the surgical bra for the time indicated. See the full guide: Post-surgical recovery and care.
Before and after
Most patients want to see before-and-after photographs before deciding. Out of respect for each person’s privacy, Dr. Arístides Arellano shows real cases —always with documented consent— during your in-person consultation, where you can review results from patients with a starting point similar to yours. Results may vary from patient to patient.
Approximate price
Breast asymmetry correction has no single catalogue price, because it is not a single procedure: cost depends on which combination is needed —implants, fat grafting, a lift or a reduction— and on whether one breast or both are operated on. That is why it is defined at the consultation, with a written plan and before scheduling surgery. Approximate price — the definitive cost is set at your private consultation with Dr. Arístides Arellano. See the price list.
About Dr. Arístides Arellano
Dr. Arístides Arellano is a plastic surgeon holding a specialty licence: he practises under a Mexican medical licence (D.G.P. 1125959) and a specialty licence in Plastic & Reconstructive Surgery (0002008), both issued by the Directorate General of Professions (DGP), which reissued his certificate of professional standing in 2025. His career began before Mexico’s present-day specialty-board system existed: he belongs to the founding generation of plastic surgery in Puebla, the second generation of a surgical tradition started in 1971 by Dr. Francisco Arellano Ocampo. Trust is verified, not promised: both licences are public and anyone can look them up in the DGP’s National Registry of Professionals.

Recovery · step by step
- Days 1–3Relative rest, swelling and discomfort managed with prescribed analgesia; the surgical bra is worn continuously.
- Week 1Post-operative review; most patients resume light desk activity, avoiding effort with the arms.
- Weeks 2–4Visible swelling decreases; social activity resumes gradually as medically advised.
- Weeks 4–6Exercise and greater effort are progressively authorised; shape and symmetry begin to settle.
- Up to 6 monthsThe result stabilises as the breasts settle; in cases with fat grafting, the retained fat becomes defined.
Frequently asked questions
How much does breast asymmetry correction cost in Puebla?
There is no single price, because the cost depends on what is needed: differently sized implants, fat grafting, a lift or a reduction, and whether one breast or both are operated on. The exact amount is defined at the in-person consultation, with a written plan and before scheduling surgery.
Is it normal to have one breast larger than the other?
Yes. Mild asymmetry between the two breasts is normal and most women have it; it needs no surgery. Correcting it is considered when the difference is noticeable enough to affect clothing, the balance of the silhouette, or how the patient sees herself.
How is a size difference between the breasts corrected?
It depends on the magnitude. Small differences can be evened out with the patient’s own fat; larger ones by placing a differently sized implant on each side, reducing the larger breast, or combining an augmentation with a lift. The technique is decided at the assessment, measuring each breast separately.
What is a tuberous breast?
It is a developmental asymmetry in which the breast base is narrow and the areola tends to protrude, giving a constricted or tubular shape. It can affect one or both breasts, and correcting it usually requires releasing the tissue, reshaping the base and, often, an implant.
Can asymmetry be corrected with fat grafting instead of implants?
Yes, when the volume difference is mild or moderate and the patient has enough fat to harvest from another area. Fat grafting avoids implants in those cases and helps refine the contour; its suitability is assessed per patient, since part of the grafted fat is reabsorbed.
At what age can breast asymmetry be operated on?
Generally once breast development is complete. For asymmetry that appears in adolescence, the assessment considers whether it is better to wait until the breasts finish developing before operating, unless there is a specific indication discussed case by case.
Does the result leave the breasts exactly the same?
The goal is much greater, natural-looking symmetry, not two mathematically identical breasts. Perfect symmetry does not exist even naturally; surgery aims to balance size, shape and position so the difference is no longer noticeable. Results may vary.
