Apocrine Metaplasia

What it is

Apocrine metaplasia is a harmless condition where some cells lining your breast ducts change. These cells become larger and look like the cells found in sweat glands. This is a very common part of how breast tissue can change over time.

How common it is

This is a very common finding, especially during your reproductive years and beyond. It is often found by chance on a mammogram or a biopsy that was done for another reason.

What you may notice

Most of the time, you will not notice anything at all. Occasionally, these changed cells can form a small, fluid-filled cyst that you might feel as a small, soft lump. In rare cases, it might cause nipple discharge.

What can contribute

The exact cause is not known, but these changes are thought to be related to the normal hormonal shifts that happen in your body.

How it is usually checked

Your provider usually finds apocrine metaplasia on a routine mammogram or ultrasound. If a biopsy is needed for any reason, a specialist looks at the tissue sample under a microscope to identify the cells and confirm what they are.

Does this change my long-term risk?

Finding simple apocrine metaplasia is considered harmless. On its own, it does not change your long-term breast health risk.

Comfort and everyday care

• Wearing a comfortable, well-fitting bra can help with general breast comfort.
• Some women find that maintaining a balanced diet helps them feel their best overall.
• Gentle stress management techniques, like deep breathing or taking a walk, can support your general well-being.
