Small or Asymmetrical Breasts
Small or asymmetrical breasts are common variations in female breast anatomy. Small breasts (micromastia) may be due to genetic factors, hormonal influences, or developmental issues. Breast asymmetry, where one breast differs from the other in size, shape, or position, affects most women to some degree, though significant asymmetry may cause physical discomfort or emotional distress. These conditions are not medical concerns but may impact body image and self-confidence. Both can be addressed through various surgical and non-surgical approaches, depending on individual anatomy and personal goals.
Causes
- Genetic factors - Breast size and shape are largely determined by hereditary traits passed down through families.
- Hormonal variations - Differences in hormone levels during development can affect breast growth and may contribute to asymmetry.
- Developmental conditions - Conditions like tuberous breast deformity or Poland syndrome can cause underdevelopment or significant asymmetry.
- Puberty variations - Differences in the timing and progression of development during puberty can lead to asymmetry.
- Weight fluctuations - Significant weight changes can affect breast tissue differently on each side.
- Pregnancy and breastfeeding - Changes during pregnancy, lactation, and weaning can alter breast size and shape, sometimes asymmetrically.
- Trauma or surgery - Injury to the chest or previous surgeries, including biopsies, can affect breast development or appearance.
- Scoliosis or skeletal asymmetry - Differences in the underlying chest wall structure can create apparent breast asymmetry.
- Juvenile hypertrophy - Rare condition causing one breast to grow significantly larger than the other during puberty.
- Aging - Natural aging processes can affect breasts differently, potentially increasing asymmetry over time.
Signs and Symptoms
- Noticeable difference in breast size between left and right sides
- Variation in breast shape or projection between breasts
- Differences in nipple or areola size, shape, or position
- Underdevelopment of one or both breasts
- Conical or tubular shape to one or both breasts
- Abnormal or constrained lower breast development
- Physical discomfort from uneven weight distribution with significant asymmetry
- Difficulty finding properly fitting bras and clothing
- Breast size disproportionately small relative to body frame
- Psychological impacts including self-consciousness, body image concerns, or reduced confidence
- Potential physical discomfort during physical activities with significant asymmetry
Diagnosis
Physical Examination
A plastic surgeon will perform a comprehensive breast examination to assess the degree of asymmetry or size concerns. They will evaluate differences in breast volume, shape, position, skin quality, nipple-areola complex position and size, and the underlying chest wall structure. Measurements of breast dimensions help quantify the asymmetry and plan appropriate treatment.
Medical History Review
Your doctor will discuss your medical history, including breast development, previous breast conditions or surgeries, family history of breast abnormalities, pregnancy history, and weight fluctuations. They'll also ask about when you first noticed the asymmetry or concerns about breast size, and whether there have been recent changes.
Imaging Studies
For significant asymmetry, imaging may be recommended to rule out underlying breast conditions. Ultrasound is often used for younger patients, while mammography may be appropriate for older women. These imaging studies ensure there are no masses, cysts, or other abnormalities causing or contributing to the asymmetry.
Photography
Clinical photographs are typically taken from multiple angles to document the current appearance, assess the degree of asymmetry, and aid in surgical planning. These images help both the surgeon and patient discuss specific concerns and desired outcomes.
Three-Dimensional Imaging
Some practices offer 3D imaging technology that can measure breast volume differences more precisely and simulate potential surgical outcomes. This can be particularly helpful for visualizing how different implant sizes or surgical approaches might address asymmetry.
Treatment Options
Non-Surgical Approaches
For mild asymmetry or those who prefer non-surgical options, specially designed bras, breast forms, or inserts can help create the appearance of symmetry when clothed. Push-up bras, bras with removable padding, or custom-fitted bras may be used to compensate for size differences. While these approaches don't address the underlying asymmetry, they offer a non-invasive way to achieve a balanced appearance in clothing.
Breast Augmentation
For small breasts or asymmetry, breast augmentation using implants can increase volume and improve symmetry. Different sized implants may be used on each side to correct asymmetry. Silicone or saline implants of various sizes, shapes, and profiles can be selected based on individual anatomy and goals. The procedure involves creating a pocket for the implant either behind the breast tissue or beneath the chest muscle.
Fat Transfer Breast Augmentation
This technique uses liposuction to harvest fat from other areas of the body (such as abdomen, thighs, or flanks), which is then processed and injected into the breasts to add volume. For asymmetry, different volumes can be added to each breast. This approach provides a modest increase in size using the patient's own tissue, with the added benefit of contouring the donor areas.
Combination or Specialized Procedures
Complex asymmetry may require tailored approaches. Options include breast lift (mastopexy) combined with augmentation; breast reduction on the larger side; correction of tuberous breast deformity through specialized techniques; or adjusting the inframammary fold position. These procedures are customized to address specific anatomical issues contributing to the asymmetry.
Home Remedies
Specialized Bras and Inserts
Invest in bras designed to address asymmetry, with features like removable padding or pockets for inserts. Partial breast forms or "cookies" can be placed in the bra cup of the smaller breast to create balance. Various products range from simple foam inserts to more realistic silicone forms that mimic breast tissue.
Clothing Choices
Select tops and dresses with design elements that minimize the appearance of asymmetry. Ruching, draping, patterns, layers, and strategic necklines can all help camouflage differences. Avoid form-fitting tops or those made of thin, clingy fabrics if you're concerned about asymmetry being noticeable.
Chest Exercises
While exercises cannot significantly change breast size (as breasts consist primarily of fat and glandular tissue, not muscle), strengthening the pectoral muscles beneath can improve chest appearance and posture. Push-ups, chest presses, and chest flies help develop the chest muscles, potentially creating a more balanced appearance.
Posture Improvement
Poor posture can accentuate breast asymmetry. Practice standing and sitting with shoulders back, spine straight, and chest open. Regular posture-focused exercises like yoga, Pilates, or specific posture correction stretches can help develop the habit of better alignment.
Self-Acceptance Practices
Some degree of breast asymmetry is normal and extremely common. Practicing positive self-talk, mindfulness, and body acceptance can help manage emotional aspects of concerns about breast appearance. Consider working with a therapist specializing in body image if these concerns significantly impact your well-being.
Preventive Care
- Maintain a stable weight, as fluctuations can affect breast tissue and potentially worsen asymmetry.
- Wear properly fitted, supportive bras to maintain breast position and minimize stretching of breast tissue over time.
- Consider professional bra fitting to ensure you're wearing the correct size and style for your breast shape and any asymmetry.
- Perform regular breast self-exams to monitor for any changes in breast tissue, especially if asymmetry is new or changing.
- Attend recommended screening mammograms and other breast imaging as advised by your healthcare provider.
- Practice good posture to prevent exacerbating the appearance of asymmetry due to uneven shoulders or spinal alignment.
- If considering surgery, thoroughly research qualified plastic surgeons with experience in breast asymmetry correction.
- Discuss potential impacts of pregnancy and breastfeeding on breast appearance with your doctor if you're planning future pregnancies.
- If breastfeeding, try to nurse from both breasts equally to prevent one side from becoming significantly larger than the other.
- Avoid tobacco products, as smoking can affect skin elasticity and healing if surgical correction is eventually pursued.
Surgical Options
Asymmetric Breast Augmentation
A customized approach using different sized or shaped implants for each breast to create symmetry. This procedure can address both size and shape discrepancies, with implants selected based on precise measurements of each breast. The surgeon may also use different implant placement techniques or pocket dissections on each side to achieve the most natural-looking symmetry.

For significant asymmetry, an implant may be placed only in the smaller breast to match the larger one. This approach is appropriate when one breast is well-developed and the patient is satisfied with its size, requiring enhancement only of the smaller breast to create balance.

This combination procedure addresses both size and position asymmetry by adding volume while also reshaping and repositioning the breast tissue and nipple-areola complex. Different degrees of lifting may be performed on each breast, along with potentially different sized implants, to achieve symmetry in both size and position.

Using liposuction, fat is harvested from areas like the abdomen or thighs, processed, and then precisely injected into the breasts to add volume. For asymmetry, different volumes can be added to each breast. This technique provides a modest size increase using the patient's own tissue and can create very natural results.

For asymmetry caused by tuberous breast deformity (characterized by constricted breast base, herniation of breast tissue into the areola, and underdevelopment), specialized techniques release the constricted tissues and reshape the breast. This often involves a combination of tissue expansion, implant placement, and nipple-areola complex reduction or repositioning.
