Lobular Involution

What it is

Lobular involution is the natural, gradual process where the milk-producing glands, called lobules, in your breasts get smaller and are replaced by fatty tissue. This is a normal part of your breast's life cycle as you age. It happens as your hormone levels change, especially around and after menopause.

How common it is

This is a very common and expected change. Most women's breasts go through this process as they get older.

What you may notice

You will likely not feel or see any signs of lobular involution. It is a term your provider might use to describe a normal pattern they see on your mammogram or in a tissue sample. It can make the breasts look less dense on imaging.

What can contribute

This is a natural part of aging. Your personal hormone patterns and your history with pregnancy and breastfeeding can influence how and when your breast tissue changes over time.

How it is usually checked

Lobular involution is not something you check for at home. A provider might see these normal changes on your mammogram or when looking at a tissue sample under a microscope. They may note it in your report to describe what they see.

Does this change my long-term risk?

Lobular involution is a normal part of aging. Some studies suggest women whose breast tissue goes through less involution have a slightly higher long-term breast risk, which is one more thing your provider may consider.

Comfort and everyday care

• Eating a balanced diet with plenty of fruits and vegetables can support your overall health and well-being.
