Small Breasts (Micromastia)
Also known as: flat chest · underdeveloped breasts · breast hypoplasia · micromastia · small bust · no breasts · AA cup · breasts never developed
Medically reviewed by Dr. Paulo Michels, Board-Certified Plastic Surgeon· Updated 29 September 2026
Small breasts, called micromastia or breast hypoplasia when underdeveloped, are a normal variation rather than a disease. They need treatment only if they bother you. Bras, exercise and creams do not add lasting volume; the reliable options are silicone implants, fat transfer for a modest gain, or a hybrid of both. Dr. Paulo Michels plans each option individually at Elyzee Hospital in Abu Dhabi.
Treated with
What counts as small breasts or micromastia?
“Small” is personal. There is no cup size below which breasts become a medical problem, and small breasts are healthy breasts: they respond to hormones normally, can usually breastfeed, and need no treatment for health reasons. Doctors use the terms micromastia or breast hypoplasia for breasts that are small or underdeveloped relative to the body, but these terms describe a shape, not an illness.
Women who consider treatment usually describe the same experiences: tops and dresses that do not fit the upper body, padded bras worn every day, a figure that feels out of proportion with the hips, or a lifelong feeling that the breasts never developed. Those are valid reasons to seek advice — and equally, it is entirely reasonable to decide that nothing needs to change.
What causes small breasts?
- Genetics and body build — the most common reason; breast size tends to run in families.
- Low body fat — the breast contains fat as well as glandular tissue, so very slim and athletic women often have smaller breasts.
- Developmental shape — tuberous or constricted breasts can look small because the base is narrow and the lower breast has not expanded; they need a different surgical plan from simple small breasts.
- Volume lost after pregnancy, breastfeeding or weight loss — breasts that were once fuller have deflated; see deflated breasts after pregnancy and “Ozempic breasts”.
- Hormonal conditions — occasionally, particularly when puberty itself was delayed or incomplete; these are assessed medically first.
When one breast is clearly smaller than the other, the priority is balancing the two sides, which is covered on the page on breast asymmetry.
Can small breasts be enlarged without surgery?
It is worth being direct, because a great deal of money is spent on products that do not work:
- Exercise strengthens the chest muscle behind the breast. It can improve posture and slightly lift the appearance of the chest, but it does not enlarge the breast itself.
- Pills, herbal supplements and creams have no reliable evidence of producing lasting growth, and some contain plant oestrogens whose long-term safety is uncertain.
- Vacuum pumps and devices may cause temporary swelling but no durable, meaningful increase.
- Injectable fillers are not recommended for breast enlargement. They can form lumps, move, become infected and interfere with mammograms and breast ultrasound.
- Weight gain increases breast size in some women, but unpredictably and together with the rest of the body.
What genuinely works without surgery is clothing: a well-fitted bra, a push-up or padded design, or removable inserts. These change how the breasts look in clothes, and for many women that is enough.
Which operation adds breast volume?
There are three reliable surgical options. The choice depends on how much change you want, how much breast tissue and skin you have, how much fat is available elsewhere, and whether you prefer to avoid an implant.
| Option | What it offers | Best suited to |
|---|---|---|
| Silicone implants | Predictable volume and shape, from subtle to substantial | Most women wanting a clear increase in size |
| Fat transfer | A modest, soft, natural increase with no implant | Women wanting a small change who have spare fat to donate |
| Hybrid (implant + fat) | Implant volume with softer edges and cleavage | Thin women with very little tissue to cover an implant |
Breast augmentation with implants
Breast augmentation with implants is the most predictable way to add volume. Dr. Michels uses cohesive silicone implants from premium brands (Motiva, Mentor, Polytech), with smooth or nano-textured surfaces preferred. The incision is usually placed in the fold beneath the breast, where it is hidden in the natural crease, and the implant is placed in the Dual Plane — partly behind the chest muscle, which covers the upper edge and gives a natural slope. Permanent sutures reinforcing the breast fold (the Internal Bra principle) help prevent the implant from settling too low over time.
To reduce contact between the implant and the skin during insertion, Dr. Michels uses the Keller Funnel. Before surgery, sizes and profiles are previewed on a 3D model of your own body with Crisalix 3D simulation — a planning and communication aid, not a guarantee of the final result.
Fat transfer
In fat transfer, fat is taken by gentle liposuction from the abdomen, flanks or thighs, purified and injected in small amounts throughout the breast. The result feels entirely natural and there is no implant to maintain. The limits are real: the increase per session is modest, part of the fat is reabsorbed, a second session is sometimes needed, and you need enough spare fat — which very slim women often do not have.
Hybrid augmentation
For thin patients with very little breast tissue, a hybrid augmentation combines a carefully chosen implant with fat placed around it. The implant provides the volume; the fat softens the edges and the cleavage, so the implant is less visible and less palpable.
How is the right size chosen for very small breasts?
In a very small breast, the limiting factor is the skin envelope and tissue cover, not the size you would like. Tight skin can only accommodate a certain implant width and volume comfortably. An implant chosen too large for the chest can look round and artificial, be felt at the edges, cause rippling in thin tissue and stretch the lower breast over the years. Dr. Michels measures the width of your chest and breast base and the thickness of your tissue, then shows the options within that safe range on the 3D simulation. The article on choosing breast implant size explains this process in more detail.
What does recovery look like?
- Light walking on the day of surgery
- Comfortable early days, helped by ultrasound-guided nerve blocks placed during surgery
- Support bra for 4 to 6 weeks
- Back-sleeping for 4 to 6 weeks
- No high-impact exercise or upper-body weights for 4 to 6 weeks
The implants sit high and feel firm at first and take several months to soften and settle. The recovery guide covers each week in detail.
What are the risks, and what can surgery not do?
Breast augmentation carries the risks of any operation — bleeding, infection, scarring, changes in nipple sensation — and implant-specific risks: capsular contracture (hardening of the scar capsule around the implant), rippling, malposition and rupture. A rare lymphoma, BIA-ALCL, has been associated mainly with textured implants, which is why smooth or nano-textured surfaces are preferred. Implants are not lifetime devices; further surgery may be needed in the future.
Surgery also has limits. It cannot create cleavage where the breasts are naturally far apart without risking complications — see the page on a wide gap between the breasts. It cannot guarantee breastfeeding; most women can breastfeed after augmentation, as explained in this article, but it is never guaranteed. And it does not stop the breasts from changing with time, pregnancy or weight.
When is it time to see a surgeon?
It is reasonable to seek a consultation when your breasts have finished developing, your weight has been stable for some months, you are not pregnant or breastfeeding, and the wish for change is your own. It is sensible to postpone surgery if you are planning a pregnancy soon, since pregnancy and breastfeeding change the breasts again.
How are small breasts assessed at the consultation?
Dr. Paulo Michels is a Brazilian board-certified plastic surgeon (SBCP) with more than 18 years’ experience and a member of ISAPS, ASPS and EPSS. At the consultation he measures the chest and breast, assesses skin elasticity and tissue thickness, checks for a constricted breast shape or asymmetry, and discusses the result you have in mind. The options — implant, fat transfer or hybrid — are then compared on a 3D simulation of your own body.
Surgery takes place at Elyzee Hospital in Abu Dhabi, a fully licensed private hospital, where patients from Dubai and across the UAE are seen, with visits grouped to reduce travel.

Questions, answered
Small Breasts (Micromastia) — your questions
What is micromastia?+
Micromastia — also called breast hypoplasia — is the medical term for breasts that are small or underdeveloped relative to the body. It is a description, not a disease: small breasts are healthy, function normally and do not need treatment. Surgery is considered only when the size affects how clothes fit, your proportions or your confidence, and the decision is entirely yours.
Why are my breasts small?+
Breast size is mostly determined by genetics and body build. Low body fat, as in very slim or athletic women, also means less breast volume, because the breast contains fat as well as glandular tissue. Less commonly, breasts are small because of a developmental shape such as tuberous breasts, a hormonal condition, or volume lost after pregnancy, breastfeeding or weight loss.
Can small breasts grow naturally after my teenage years?+
Breast development is usually complete by the late teens or early twenties. After that, breasts change mainly with weight, pregnancy, breastfeeding and hormonal contraception, and those changes are variable and often temporary. There is no exercise, food, supplement or cream proven to make adult breasts grow.
Do breast enlargement pills, creams or pumps work?+
There is no reliable evidence that pills, herbal supplements, creams or vacuum devices produce a lasting increase in breast size. Some products contain plant oestrogens whose safety is not well established. The honest non-surgical options are clothing and bra choices, which change how the breasts look rather than their size.
Can fillers be injected to make breasts bigger?+
Injectable fillers are not recommended for breast enlargement. Filler injected into the breast can form lumps, move, become infected and interfere with mammograms and breast ultrasound, and removal can be difficult. Where a patient wants volume without an implant, the surgical alternative is fat transfer using your own fat.
Is fat transfer a good alternative to implants for small breasts?+
It suits some patients. Fat transfer uses your own fat, taken by liposuction, so it feels natural and leaves no implant. The gain per session is modest, part of the transferred fat is reabsorbed, and a second session is sometimes needed. It needs enough donor fat, which very slim women may not have. It adds softness and a moderate increase rather than a large change in size.
What is hybrid breast augmentation?+
Hybrid augmentation combines a silicone implant with fat transfer. The implant provides reliable volume and projection; the fat is placed around it to soften the edges and the cleavage. It is particularly useful for thin patients with very little breast tissue, in whom an implant alone might be more visible or palpable at the edges.
Which implants does Dr. Paulo Michels use?+
Cohesive silicone implants from premium brands — Motiva, Mentor and Polytech — with smooth or nano-textured surfaces preferred. They are usually placed in the Dual Plane through an incision in the fold beneath the breast and inserted with the Keller Funnel, a no-touch technique. The size and profile are chosen from your measurements and previewed with Crisalix 3D simulation.
How do I choose the right size if my breasts are very small?+
The main limit is how much your skin and tissue can cover. Very small breasts have a tight skin envelope, so an implant that is too large for your chest width can look unnatural, be felt at the edges, or stretch the tissue over time. The implant is selected from the width of your chest and breast and your tissue thickness, then previewed with 3D simulation.
Can I breastfeed after breast augmentation?+
Most women can. With an incision in the breast fold and the implant placed behind the breast tissue, the milk ducts and the nerves to the nipple are largely left alone. Breastfeeding cannot be guaranteed after any breast surgery, and some women with very underdeveloped breasts have limited milk production regardless of surgery.
How long do implants last?+
Implants are not lifetime devices. They do not have a fixed expiry date, but over the years some women need further surgery — for rupture, capsular contracture, a change of size, or sagging of the breast around the implant. Many implants last well for many years; regular follow-up and imaging when advised are part of having implants.
What are the risks of augmentation for small breasts?+
Risks include bleeding, infection, changes in nipple sensation, capsular contracture (hardening of the scar tissue around the implant), rippling, implant malposition and rupture. A rare lymphoma, BIA-ALCL, has been associated mainly with textured implants, which is one reason smooth or nano-textured surfaces are preferred. These risks are discussed individually at the consultation.
What is recovery like after breast augmentation?+
Light walking starts immediately. Ultrasound-guided nerve blocks keep the first days comfortable. A support bra is worn for 4 to 6 weeks; back-sleeping is recommended for 4 to 6 weeks; and high-impact exercise and upper-body weights are avoided for 4 to 6 weeks. The implants take several months to soften and settle into their final position.
How much does breast augmentation for small breasts cost?+
Costs are individual and depend on the implant chosen, whether fat transfer or a hybrid approach is added, and the details of your surgery and hospital stay. A personalised quote is given after the consultation, once the plan has been defined with you; no price list is published, because no two plans are the same.
