Adenosis

What it is

Adenosis is a benign, or non-harmful, condition where the milk-producing glands, called lobules, are larger and more numerous than usual. These glands are a normal part of your breast tissue. Adenosis just means there is more of this glandular tissue than is typical.

How common it is

This is a very common finding in breast tissue. It is often seen in women during their reproductive years and around the time of menopause.

What you may notice

Often, adenosis causes no symptoms at all and is only found during a mammogram or biopsy for another reason. If it is large enough, you might feel a lump or a lumpy area. Some women also notice breast pain or tenderness that can come and go with their cycle.

What can contribute

The exact cause is not always known, but adenosis is thought to be related to the normal hormonal changes that happen during your menstrual cycle or pregnancy.

How it is usually checked

If you or your provider feel a lump, or if an area looks different on your mammogram, you may have more imaging like an ultrasound. To be certain what the area is, a provider may suggest a biopsy, which is when a tiny sample of tissue is taken for a closer look under a microscope.

Does this change my long-term risk?

Most of the time, adenosis does not change your long-term breast health risk. A specific type, called sclerosing adenosis, may slightly raise your long-term breast risk, which is why your provider may suggest a follow-up plan.

Comfort and everyday care

• A warm compress or a supportive, well-fitting bra can help ease any breast tenderness.
• Some women find that limiting caffeine or eating a diet lower in fat can help with general breast pain, though this may not help everyone.
• Gentle exercise and stress-reducing activities like yoga or meditation may help you feel better overall.
