Is Underarm Fullness Caused by Axillary Breast Tissue?

If you notice a bulge near the outer breast or armpit, it could be fat, loose skin, or accessory breast tissue. When the area stays full after weight loss, feels tender around your period, or rubs against clothing, an evaluation can help you find out what’s causing it and what your options are.

At Halvorson Plastic Surgery, we match axillary breast tissue removal in Asheville to what’s causing your fullness. Your treatment might involve liposuction, surgical excision, or a combination of both.

How Does Axillary Breast Tissue Differ From Ordinary Fat?

Axillary breast tissue develops along the embryonic milk line and may include fat, glandular tissue, skin, or a nipple or areola. A 2023 clinical study of axillary breast tissue management found that tissue type, skin laxity, and an accessory nipple can guide procedure planning.

You may notice:

• Fullness where the outer breast meets the underarm
• Tenderness or swelling that changes with your menstrual cycle
• More noticeable tissue during pregnancy or breastfeeding
• Chafing, clothing irritation, or restricted arm movement
• A bulge that remains despite weight changes

These signs can point to accessory breast tissue, but only an examination will tell for sure. An exam helps sort out whether you’re dealing with glandular tissue, ordinary fat, or loose skin.

When Should You Have Underarm Fullness Checked?

A new or growing lump needs medical evaluation. Mayo Clinic recommends having a new or enlarging armpit lump checked, especially if it feels firm or appears with skin changes.

If the area changed quickly, became painful, feels hard, or showed up on just one side, see a doctor before considering cosmetic treatment. Underarm swelling can have several causes, so it’s important to get checked first.

Does Liposuction or Excision Work Better?

Liposuction can help if fatty tissue is causing most of the bulge. Surgical excision works better for firmer glandular tissue or extra skin that liposuction can’t remove. If you have both, combining these techniques can help create a smoother contour between your breast and underarm.

When you come in for a consultation for axillary breast tissue removal in Asheville, Dr. Halvorson will look at your tissue, skin quality, and symmetry. Your procedure will be tailored to your anatomy.

What Results Can Axillary Breast Tissue Removal Provide?

Surgery can reduce underarm fullness, chafing, and irritation, and help create a smoother contour. It only treats a specific area and won’t affect your overall weight.

You can expect a scar, some temporary swelling, and changes in contour as you heal. Surgery can’t guarantee perfect symmetry or a scar that’s completely hidden. Weight changes, pregnancy, and aging can also affect the area over time.

FAQ

Can axillary breast tissue return after removal?

Once the tissue is removed during surgery, it usually doesn’t come back. The surrounding fat and skin can still change with weight, hormones, pregnancy, or aging.

Can I combine removal with another breast procedure?

You might be able to combine removal with a breast lift, reduction, or augmentation if it fits your health, anatomy, and recovery plan.
