Causes (sweat glands and odor mechanisms)

On the skineccrine glandapocrine glandThere are two types of sweat glands (sweat-producing organs).
The main causes of axillary odors areapocrine glandis.

  • eccrine glandWidely distributed throughout the body. Mainly water and involved in the regulation of body temperature.
  • apocrine glandThe most common areas are: armpits, vulva, (ear canal, eyelid rim, nose, nipples, etc.) and other areas with pores.

The secretions of the apocrine glands contain lipids and proteins, which are broken down by the action of bacteria on the skin surface,
It is believed that the odor characteristic of axillary malodorsis occurs.

Factors related to deterioration (genetics, puberty, stress, etc.)

The general commentary of the Japanese Society of Plastic Surgeons also states that the following factors are involved in the development and secretion of apocrine glands

  • genetic predisposition(may be seen within the family)
  • sex hormone (e.g. estrogen, testosterone)(noticeable since puberty)
  • Amount of armpit hair
  • psychological factor(stress, tension, etc.)
  • Sweating due to sports, etc.

In other words, "sweating does not necessarily mean armpit cancer," but rather a combination of sweat gland type, secreted components, and lifestyle background may result in a strong odor.

Guideline for medical examination / Self-check

An objective evaluation in a medical examination is recommended if any of the following situations exist

  • Family members, roommates, or close relations pointed out the odor.
  • Yellowing and odor residues easily appear on the sides of clothing
  • Lack of improvement with antiperspirants and deodorants
  • High stress at school, work, or in interpersonal situations

The perception of odor varies from person to person, and it is possible for a patient to be strongly bothered by an odor that is medically very mild (or of a different cause).
In such cases, do not rush into surgery, but proceed first by sorting out the cause.
