Women’s bodies can change in different ways at every life stage — from puberty to pregnancy to menopause. In your 40s, for example, you may start to notice breast changes during perimenopause into menopause.

Fortunately, you don’t need to become an expert in breast health to know if something may be off. Here we’ll cover which breast changes are not uncommon after 40 and what breast changes to be on the look out for as you age.

Common Breast Changes After 40

While the average age of menopause in the United States is 51, the decade-long period leading up to it — known as perimenopause — brings it’s own host of symptoms and bodily changes.¹

As estrogen and progesterone levels fluctuate and then eventually decline, you may notice breast changes—many of which often accompany aging or changes in weight. Some of the more common breast changes experienced during menopause can include: ^{2,3,4, 5 6}

Breast Pain: Breasts may feel tender, achy, heavy, or throbbing. “Cyclic breast pain” may occur the week before your period during perimenopause, while “noncyclic breast pain” occurs randomly, may be periodic or constant, and may continue into postmenopause.
Nipple Sensitivity: Nipples may increase in sensitivity or you may experience some nipple pain.
Breast Cysts: Benign (non-cancerous) breast cysts, also known as fibrocystic breast cysts, may develop during perimenopause. These cysts may fluctuate in size throughout the menstrual cycle and cause tenderness if they are larger.

Breast Changes to Pay Attention to in Perimenopause

Certain breast changes are an uncommon part of aging. However, it’s important not to assume that every change you experience is menopause driven. Understanding what’s normal for you can help you recognize any changes that warrant a visit with a healthcare provider, including: ^7,8

A lump or firm area in or near the breast or underarm
A change in size in one or both breasts
Skin changes on the breasts, including dimpling, puckering, thickening, or skin that resembles an orange peel
Redness and/or swelling. In women with darker skin, concerning changes may appear as skin that is darker, red, or purple compared to surrounding skin.
Nipple inversion (nipples turning inward), nipple flattening, or changes in the shape or direction of the nipple (that don’t correlate with temperature changes or sexual stimulation)
Scaling, peeling, crusting, or flaking breast skin
Nipple discharge unrelated to pregnancy or breastfeeding (especially if bloody)
Changes in nipple appearance, including sores, rashes, or skin changes that don’t heal

When to See a Healthcare Provider for Breast Changes

Health experts recommend most women begin breast cancer screenings by age 40, or earlier if you have a familial or personal history of cancer.⁹ However, if you experience any of the breast changes discussed here, it’s important to consider scheduling an appointment with a healthcare provider. When caught early, many early-stage breast cancers are both detectable and treatable, so it’s always best to err on the side of caution if you have any new symptoms or concerns.¹⁰

Breast Health After 40 Starts with Awareness

Knowing your body is the first step in advocating for your health and well-being, through perimenopause and beyond.

If you experience breast changes, no matter your age or life stage, be sure to talk with a healthcare provider about evaluating your symptoms and receiving recommendations for additional testing, if necessary.
