Key Takeaways

Breast changes during perimenopause are common and can include shifts in size, shape, firmness, sensitivity, and tissue composition due to changing hormone levels.

Sometimes when faced with yet another change during perimenopause, you think to yourself: “What else will I have to deal with?!” Well, you’re not alone if you’re experiencing breast changes.

Menopausal symptoms can affect physical and mental health in numerous ways, including changes to your breasts’ shape, size, fullness, firmness, and sensitivity. Many breast changes are normal. But in some cases, you may experience changes in your breasts that are a sign of something more serious.

Here’s more on how your breasts may change during perimenopause and what might be worth sharing with your doctor. There are treatment options that can help relieve uncomfortable breast changes as well as other menopausal symptoms.

🗳️ Have you noticed changes to your breasts during perimenopause or menopause?

Yes

Normal Breast Changes During Perimenopause

In perimenopause, your body starts to lose estrogen, among other hormonal changes. Estrogen plays a role in many different functions in the body, including sexual reproduction and breast development.

Changes to Breast Tissue Composition

As estrogen levels fall during perimenopause, physical aspects of the breast tissue can change. There’s a decrease in gland tissue and the connective tissue starts to have less elasticity. These are normal changes that can make the breasts feel smaller and less firm.

Size Changes Due to Weight Gain

In some cases, breast size may increase due to weight gain. Decreasing estrogen and aging in general affect the body’s metabolism and are factors in weight gain during perimenopause and postmenopause.

Benign Cysts

It’s also normal for your breasts to develop lumps during perimenopause. These are usually breast cysts, which are noncancerous fluid-filled sacs within the breast tissue. They may not be immediately noticeable or cause any discomfort.

Changes to the Nipple

The nipple, as well as the areola, the darker skin around the nipple, can also change. The areola can become smaller or less visible, and the nipple can flatten or turn inward. This occurs because milk ducts under the nipple typically dilate (expand) during perimenopause. This normal process is known as ectasia.

Pain and Tenderness in the Breasts

“I woke up with joint pain and breast tenderness. Today will be a long day because of it,” one woman wrote.

Fluctuating estrogen and progesterone levels during perimenopause can cause uncomfortable and painful symptoms that include:

Pain in one or both breasts that may be experienced as throbbing, aching, burning, or stabbing
Tenderness in one or both breasts that makes them sensitive to touch or contact
Pain or sensitivity in one or both nipples

Breast pain or tenderness may also be associated with your menstrual period, where your breasts become sore during the same phase of your cycle. These symptoms can occur a week or 10 days before your period starts. However, your cycle can become irregular during perimenopause, which could mean the cause of the breast soreness is harder to pinpoint.

Noncancerous breast cysts can also become tender or painful. Cysts can get larger or smaller at different points in your menstrual cycle.

In some cases of ectasia, the nipple may become tender or painful if the milk ducts under the nipple become blocked, inflamed, or infected. This can be painful and cause a sticky discharge from the nipple, which will require medical attention.

Hormone Therapy and How It May Impact the Breasts

Many women choose to have menopause hormone therapy (sometimes called hormone replacement therapy) during perimenopause and menopause. Hormone therapy can help control menopausal symptoms such as hot flashes, vaginal dryness, painful sex, and mood swings that may cause depression or anxiety.

However, hormone therapy can also cause breast tenderness or pain. Hormone therapy restores premenopausal levels of estrogen, which causes the milk ducts and glandular tissue in the breast to swell.

When the breasts swell due to increased estrogen, fluid can build up in the breast and cause pressure or noncancerous cysts that result in pain or tenderness. The shape and size of existing cysts may also change with hormone therapy.

Breast Changes That May Be Serious

Certain breast changes are not caused by perimenopause and a normal drop in estrogen. A lump or nipple discharge can be a sign of breast cancer.

Most lumps in the breast aren’t caused by breast cancer. But some lumps may be cancerous. Lumps that are firm, thick, or under the arm can be a sign of cancer. Any unfamiliar change in the breast may be a sign of breast cancer and should be discussed with your healthcare team.

Discharge from the nipple, changes in the nipple itself, and changes to the skin on the breast may also be a sign of breast cancer. Skin changes on the breast that may be a sign of cancer include:

Itchiness or discoloration
Darkening of skin
Scaling on the skin
Dimpling or puckering on the skin or nipple
Unusual swelling

It’s essential to talk to your doctor if you experience any changes in the breast that seem unusual.

Menopause and Breast Cancer Risk

As you age and approach menopause, you have an increased risk of breast cancer. Approximately 80 percent of breast cancer cases occur in women over the age of 50. Other factors, such as a family history of breast cancer and your overall health can also increase your risk of breast cancer.

Some research indicates that going through menopause later in life may increase the risk of breast cancer. This is believed to be caused by a greater lifetime exposure to estrogen during menstrual cycles.

Some studies have shown that women over the age of 50, who don’t have a history of breast cancer, may have a slightly higher risk of developing breast cancer if they take combination hormone therapy (estrogen plus progesterone) long term (for more than five years).

Higher-dose hormone therapy may also increase the risk of breast cancer. Talk to your doctor about your individual risk factors if you’re considering hormone therapy for symptoms of perimenopause.

It’s also important to know that breast pain and tenderness is uncommon once you’ve reached menopause and your periods have permanently stopped. If you experience new breast pain at this stage, be sure to reach out to your doctor.

How To Support Your Breast Health

Because breast changes during perimenopause and after menopause may be confusing, it’s essential to have regular breast screenings. Early detection of issues can help ensure you get the treatment you need in a timely manner.

Breast cancer screening includes the following tests and exams:

Physical breast exam with a healthcare provider to detect unusual changes or lumps in the breast
Mammogram, which uses low-dose X-rays
Ultrasound imaging or magnetic resonance imaging (MRI) if more detailed imaging is needed

Depending on your particular risk factors, your healthcare provider will advise you on which testing you may need and how often you should have breast cancer screening.

You can also help protect your breast health with healthy lifestyle choices that support your overall health. Some steps you can take include:

Maintaining a healthy weight, supported by a healthy diet
Getting physical activity and regular exercise
Limiting the amount of alcohol you consume
Quitting smoking

If you need help with lifestyle changes, talk to your healthcare team for support. Also be sure to follow your doctor’s guidelines for yearly mammograms to help monitor and protect your breast health.
