— Why Treating Axillary Breast Tissue (Accessory Breast) Is Essential —

A refined upper body is not defined by slimness alone.

It is defined by the continuity of lines from the shoulders to the breasts.

One commonly overlooked area is the axillary breast tissue, often referred to as accessory breast tissue.

What Is Axillary Breast Tissue?

This refers to localized fat fullness located between the underarm and the outer breast.

When the shoulders are brought inward, this area may become more prominent and appear to “spill over” clothing, especially dresses or tight garments.

Aesthetic Impact

If left untreated, this area can:

Create irregularities along the outer breast contour

Disrupt the smooth transition between the chest and arm

Make the upper body appear heavier and less refined

Even after arm liposuction or breast augmentation,

the overall contour may remain incomplete if this area is not addressed.

Why Combined Treatment Is Important

For optimal results, we recommend addressing:

Arm liposuction

Axillary (accessory breast) fat removal

Breast augmentation when indicated

By treating these areas together, a smooth and continuous upper body contour can be achieved.

Benefits of Treating This Area

Improved transition from the underarm to the breast

More defined and natural breast contour

Better fit in dresses and garments

Important Considerations

In certain professions, such as modeling or gravure work,

some degree of fullness in this area may be preferred.

Therefore, treatment planning must be individualized based on lifestyle and aesthetic goals.

Case Overview

This case involves arm liposuction, axillary fat removal, and hybrid breast augmentation.

At 1 month post-operatively,

some swelling and firmness remain, which is expected.

The contour will continue to improve as healing progresses.

AVAN TOKYO’s Approach

At AVAN TOKYO, we do not treat isolated areas.

We design the upper body as a continuous structure, including:

Shoulders

Arms

Axillary region

Breasts

We carefully determine:

What to remove

What to preserve

Where to add volume

to achieve a refined and balanced silhouette.

Final Message

If you feel your upper body lacks refinement despite being slim,

the cause may lie in overlooked areas such as axillary breast tissue.

True aesthetic improvement comes from comprehensive design, not isolated treatment.
