Sclerosing Adenosis

What it is

This is a harmless condition where extra tissue grows inside your breast’s tiny milk-making glands, called lobules. These extra cells can get crowded and form small, firm areas. Sclerosing adenosis is not a health risk.

How common it is

Sclerosing adenosis is quite common. It is often found on breast biopsies that are done for other reasons.

What you may notice

You may feel one or more small, firm lumps, a general area of thickness, or have some breast pain. Often, though, it causes no symptoms at all and is only found on a mammogram.

What can contribute

The exact cause is not fully understood. However, it is thought to be related to the normal hormonal changes that happen in your body over time.

How it is usually checked

On a mammogram or ultrasound, sclerosing adenosis can look like other conditions. Because of this, your provider will likely recommend a biopsy to get a small sample of the tissue. This allows them to look at the cells under a microscope to confirm the diagnosis.

Does this change my long-term risk?

By itself, sclerosing adenosis is considered harmless and does not change your long-term breast health risk. Sometimes it is found alongside other types of cells, which is why your provider may suggest a specific follow-up plan for you.

Comfort and everyday care

• For any breast tenderness, a warm compress or a supportive, comfortable bra can provide relief.
• Some women find that limiting caffeine or eating a diet lower in fat helps with general breast soreness.
• Gentle movement, like walking or stretching, can support your overall well-being.
