Why are breasts different?
Paired human organs are rarely identical: there are differences in the eyes, ears, feet and mammary glands. The mammary gland develops under the influence of hormones, and the sensitivity of the tissues on the right and left may be slightly different, so one gland grows a little faster. A difference in volume of up to one size is considered normal. The position and shape of the chest, the condition of the spine and muscles also influence: with scoliosis and different shoulder heights, the chest visually appears more asymmetrical than it actually is.
- Natural difference between paired organs
- Different tissue sensitivity to hormones
- Features of the chest shape
- Scoliosis and different muscle tone
- A difference of up to one size is common.
- Leading arm and shoulder load
Asymmetry in adolescence
In girls, the breasts often begin to develop at different times, and the difference can be noticeable. This is a common situation that frightens teenagers and parents, but in most cases the difference decreases over time as development completes. It makes sense to evaluate the final result several years after the onset of puberty. The doctor's attention is required in cases when one gland does not develop at all, when the difference is very large and is accompanied by deformation, and also when a formation is palpable in the gland.
- Non-simultaneous onset of gland development
- Gradual leveling off with age
- Evaluation of the final result after growth is completed
- Psychological support for a teenager
- Seeing a doctor if there is severe deformity
- Treatment in the absence of development of one gland
When asymmetry appears later
A new asymmetry in an adult woman requires explanation. The cause may be a benign formation, such as a large cyst or fibroadenoma, which increases the volume of one gland. Swelling and enlargement of one breast with redness and pain occur with mastitis, more often during feeding. Reducing the volume of one gland is possible after surgery, trauma or radiation therapy. The situation when asymmetry is accompanied by retraction of the skin or nipple, a change in contour and a dense knot deserves special attention: such signs require the exclusion of a malignant process.
- Large cyst or fibroadenoma
- Mastitis and inflammatory changes
- Consequences of surgery or injury
- Changes after lactation
- Retraction of the skin and nipple is a reason for urgent examination
- The difference appeared in a few months
Survey
The doctor examines the breasts in a standing and lying position, assesses the symmetry, contours, condition of the skin and nipples, palpates the glands and axillary lymph nodes. Ultrasound of the mammary glands is the main method in young women: it shows the structure of the tissue and identifies cysts and nodes. Women over 40 years old and with suspicious findings are prescribed mammography. When a formation is detected, the doctor determines its nature and, if necessary, performs a biopsy. If the asymmetry is physiological and the structure of the glands is normal, routine preventive monitoring is sufficient.
- Examination and palpation by a mammologist
- Ultrasound of the mammary glands
- Mammography by age and indications
- Axillary lymph node assessment
- Biopsy to identify a formation
- Planned follow-up if the picture is normal
Correction
If the asymmetry is not associated with a disease, treatment is not required. For many women, properly selected underwear is enough: there are models and inserts that visually even out the difference. Working on your posture and strengthening your back muscles improves your appearance, especially with scoliosis. If the difference is pronounced and significantly affects well-being and quality of life, aesthetic surgery is discussed: enlargement of the smaller gland, reduction of the larger one, or a combined approach. Such interventions are performed after breast growth has completed and are not recommended to be planned immediately before pregnancy.
- Observation for physiological asymmetry
- Selection of underwear and corrective inserts
- Working with posture and back muscles
- Treatment of the identified cause
- Aesthetic correction at the request of the woman
- Surgery after completion of breast development
