Perimenopause breast pain: causes, HRT and when to worry

Name: Perimenopause breast pain: causes, HRT and when to worry
Creator: MenoWoman

Sore or tender breasts are common in perimenopause because hormone levels swing, and cyclical breast pain usually becomes less common after menopause. Breast pain alone is rarely a sign of cancer, but a new lump, nipple discharge or skin changes should always be checked.

See a doctor promptly for a new lump or thickening in the breast or armpit, even if painless, a change in breast size or shape, nipple discharge, rash or crusting, or a newly inverted nipple. Go promptly too for dimpling, an orange-peel look, or redness, swelling or warmth, especially if it spreads over days. See a doctor if pain stays in one spot, lasts more than two weeks, keeps getting worse or comes with fever, and keep up with breast screening.

Why breasts get sore in perimenopause

Breast pain, also called mastalgia, is mostly driven by hormones. Perimenopause is a time when it often gets worse, because estrogen and progesterone rise and fall unpredictably.¹

Doctors split breast pain into two types.⁴

Cyclical pain follows the menstrual cycle. It is dull, heavy or aching, usually in both breasts, and worst in the week before a period.
Non-cyclical pain has no link to periods. It feels tight, burning or stabbing and is often in one area of one breast. It can happen after menopause.¹

Cyclical pain is less common after periods stop.⁴ Breast cysts, which form when hormone changes affect the milk ducts and glands, are another common cause.⁴

Breast pain on HRT and other medicines

Breast tenderness is a known side effect of menopausal hormone therapy (HRT) and birth control pills.^4,1 Some SSRI antidepressants, some blood pressure medicines and some antibiotics can also cause it.⁴

If pain started after a new medicine or a change in dose, tell your doctor. They may be able to adjust your treatment. Do not stop or change a medicine without talking to them first.²

Other causes include an injury, a poorly fitting bra, an infection and large, heavy breasts.^2,4 Women with large breasts may also have neck, shoulder or back pain.⁴

Sometimes the pain is not in the breast at all. Some "breast" pain comes from the chest wall, such as inflammation of the cartilage where the ribs meet the breastbone (costochondritis).² A doctor can usually tell the difference by examining you.

A simple diary can help your doctor. Note when the pain starts, where it is, and whether it follows your cycle.

When to worry about breast pain

Breast cancer risk rises with age. Even so, breast pain is usually not a sign of breast cancer when it is the only symptom.^2,4 A rare type called inflammatory breast cancer can cause tenderness across the breast, along with redness and swelling.⁴

The signs that matter most are changes you can see or feel, not pain alone. These include a new lump, nipple discharge or skin changes. See the box above for the full list.

A doctor will usually start with questions and an exam of your breasts and armpits. Most people need nothing more.¹ If anything needs a closer look, they may arrange a mammogram or ultrasound.¹ Pain is not a reason to skip screening. Follow the breast screening program where you live, and ask your doctor what applies to you.

Easing sore breasts

Most hormone-related breast pain settles over time. These steps may help in the meantime:

a well-fitted, supportive bra, with a new fitting now and then, as breast size changes over time²
gentle warmth on the sorest area, protecting your skin²
over-the-counter pain relief, such as tablets or a gel rubbed on the skin, if your doctor or pharmacist says it suits you²
cutting back on caffeine and fatty foods^2,4

Evening primrose oil is often sold for breast pain, but the research suggests it probably works no better than a placebo.³

Give these steps a couple of weeks. If the pain does not ease after two weeks, wakes you at night, gets in the way of daily life or keeps getting worse, see your doctor rather than waiting.^2,4 They can look for other causes and talk through prescription options if needed.¹

What helps: options rated

Option	Evidence	What the research shows
Reviewing hormone medicines with a doctor	Some evidence	HRT and birth control pills are known causes of breast pain, so a doctor may suggest a change if pain started with treatment.^4,1
Supportive, well-fitted bra	Weak evidence	Widely advised and low risk, especially for large breasts, but there is little trial evidence.²
Over-the-counter pain relief	Weak evidence	Tablets or a gel on the skin are commonly suggested. Trials of these in perimenopausal breast pain are lacking. Ask a pharmacist what suits you.²
Less caffeine and fat	Weak evidence	Some research links a high-fat diet with breast pain, and a lower-fat diet is suggested. The evidence for cutting caffeine is weak.^4,2
Evening primrose oil	Weak evidence	Probably no better than a placebo for breast pain, according to the NIH center for complementary health.³
