Squamous Metaplasia

What it is

Squamous metaplasia is a benign, or non-harmful, condition where cells inside your breast ducts change form. The cells that normally line the ducts transform into cells that are similar to skin cells. This is just a change in cell type, not a growth.

How common it is

This is an uncommon finding on breast biopsies. It is not something you would typically feel or see on your own.

What you may notice

You will likely not notice any symptoms. Squamous metaplasia is usually found by a pathologist looking at breast tissue from a biopsy under a microscope.

What can contribute

The exact reason for this change is not always clear. It is sometimes linked to long-term inflammation, irritation, or other benign breast conditions.

How it is usually checked

This finding is diagnosed by looking at a tissue sample from a needle biopsy or surgical biopsy. Your provider may have recommended a biopsy because of a finding on your mammogram or ultrasound, or to check another breast condition.

Does this change my long-term risk?

By itself, squamous metaplasia is benign and does not change your long-term breast health risk. It is sometimes seen alongside other breast findings, which your provider will review with you.

Comfort and everyday care

• Eating a balanced diet full of fruits, vegetables, and whole grains can support your overall body health.
• Gentle movement like walking or stretching can help you feel good and manage stress.
• Some women find that wearing a well-fitting, supportive bra can improve general breast comfort.
