Your Concerns
Are you facing any of these concerns?
I have a bulge by the side of my armpit that concerns me.
When I wear a bra or a tank top, the side of my chest looks like it protrudes.
When I lower my arm, the front of the armpit stands out.
Before my period or after pregnancy, that area becomes larger and tender.
I have heard it can come back if only liposuction is done, and it worries me.
If any of these concerns resonate,
now is the time to speak with a specialist.

Why Liposuction Alone May Not Be Enough for Accessory Breast
Accessory (axillary) breast is residual glandular tissue that remains in the armpit or by the side of the chest. It is not made of fat alone — in many cases glandular tissue is mixed in as well. For this reason, liposuction alone can leave the gland behind, resulting in an uneven texture or a bulge that becomes prominent again over time.
At Umnagumo, we first assess the ratio of fat to glandular tissue during diagnosis, then determine whether liposuction alone is sufficient or whether glandular excision should be combined. Addressing both volume and texture together is what helps to reduce the risk of recurrence.
The incision uses the natural crease of the armpit to reduce the scar burden, and the suture tension and extent of dissection are controlled precisely. Because the armpit is an area through which nerves and lymphatics pass, a careful approach grounded in anatomical understanding is important.
Enlargement and tenderness that accompany the menstrual cycle, pregnancy, or breastfeeding are common, so consultation addresses not only cosmetic goals but also the improvement of everyday discomfort. In men, accessory breast in the armpit is a distinct condition from gynecomastia, differing in both location and cause.
At Umnagumo, all procedures are performed personally by a breast-surgery specialist with 25+ years of experience, in collaboration with anesthesiology specialists and under a comprehensive safety-management system. Accessory breast, too, is approached with an individualized plan matched to the tissue composition rather than a uniform method (individual results may vary).

FAQ
Accessory Breast Removal FAQ
It depends on the tissue composition. Where the fat proportion is high, liposuction alone may be sufficient; where there is a significant amount of glandular tissue, combining glandular excision helps to avoid a residual bulge or recurrence. The method is decided after diagnosis of the fat-to-gland ratio.
If the glandular tissue is not adequately addressed, recurrence is possible. Designing liposuction together with glandular excision according to the tissue composition helps to reduce the risk of recurrence. Hormonal changes (pregnancy and breastfeeding) may also have an influence. Results vary by individual.
The incision is minimized along the natural crease of the armpit, and the scar tends to fade between the folds over time. The extent of the scar varies with skin type and the extent of excision, so individual variation applies.
Return to daily life is generally possible relatively early. In the early phase, compression management and limiting arm and shoulder use are recommended. Strenuous exercise is resumed in stages according to progress, and recovery varies by individual.
During pregnancy and breastfeeding, hormonal changes can cause the tissue to enlarge again. If you are planning a pregnancy in the near future, we discuss timing after childbirth and breastfeeding together during consultation.
Fat-dissolving injections are sometimes mentioned, but the indications are limited and little effect can be expected on glandular tissue. They are not recommended for every case of accessory breast, and suitability is judged after diagnosis of the tissue composition.
Men can also develop accessory breast in the armpit. This is a separate condition from gynecomastia — in which the glandular tissue at the front of the chest enlarges — differing in both location and cause. A suitable method is advised after examination.
The cost varies with the size and location of the accessory breast, the tissue composition, the extent of excision, the anesthesia method, and whether one or both sides are treated. Rather than a fixed comparison or event price, we advise an individualized estimate based on the diagnostic findings, provided through consultation.
