Lobular Hyperplasia

What it is

Lobular hyperplasia means there are more cells than usual growing inside the tiny glands, or lobules, where breast milk is made. This is a benign (not harmful) finding. The cells themselves are normal, there are just more of them than expected.

How common it is

This is a common finding, and it is often found by chance when a breast biopsy is done for another reason.

What you may notice

Often, you will not notice any symptoms at all. If you do, you might feel an area of lumpiness or experience some breast pain or tenderness.

What can contribute

The exact cause is not fully understood. It is thought to be related to the normal hormonal changes your body goes through over your lifetime.

How it is usually checked

Your provider may see an area on a mammogram or ultrasound that needs a closer look. To confirm what it is, they may suggest a biopsy, where a tiny sample of tissue is taken to be studied.

Does this change my long-term risk?

Lobular hyperplasia itself does not change your long-term breast health risk. If your report mentions 'atypia' (called atypical lobular hyperplasia), this may slightly raise the long-term risk, and your provider may suggest a plan for closer follow-up.

Comfort and everyday care

• Wearing a supportive, well-fitting bra may help ease general breast tenderness.
• Some women find that limiting caffeine can help reduce breast pain and tenderness.
• A warm compress or a relaxing bath can sometimes provide comfort for sore breasts.
