Lactating Adenoma

What it is

A lactating adenoma is a harmless, solid lump made of milk-producing cells. These lumps are a response to the normal hormonal changes that happen during pregnancy and breastfeeding. They are not contagious and do not spread.

How common it is

Lactating adenomas are not very common. They are found in a small number of women during pregnancy or while they are breastfeeding.

What you may notice

You might feel a smooth, firm, and moveable lump in your breast. It is usually not painful.

What can contribute

The main reason these lumps form is because of the normal hormonal shifts your body goes through to prepare for and support breastfeeding.

How it is usually checked

Your provider will likely do a physical exam. They may also suggest an ultrasound to get a better look at the lump. Sometimes, a small sample of the lump, called a biopsy, is taken to confirm what it is.

Does this change my long-term risk?

Having a lactating adenoma does not change your long-term breast health risk. These lumps usually shrink and go away on their own after you stop breastfeeding.

Comfort and everyday care

• Wearing a supportive, comfortable bra can help ease any discomfort.
• Some women find that continuing to breastfeed or pump regularly from both breasts helps.
• Ensure you are getting enough rest, as your body is working hard during this time.
