Breast Pain (Mastalgia): Causes, Warning Signs & Relief

What is breast pain?

Breast pain (mastalgia) can feel like tenderness, heaviness, aching, burning or sharp twinges in one or both breasts, sometimes spreading to the armpit. Most women experience it at some point. On its own, breast pain is rarely a sign of breast cancer, but it is important to know which features need medical attention.

Cyclical breast pain

Cyclical pain is linked to the menstrual cycle. It usually starts in the days before a period, affects both breasts – often the upper outer areas – and eases when the period starts. It is most common in the 30s and 40s and usually stops after the menopause. Hormonal contraception, fertility treatment and hormone replacement therapy can also cause tenderness. Lumpy, tender breasts, described as fibrocystic changes on our breast lumps page, are part of the same picture.

Non-cyclical breast pain

Non-cyclical pain does not follow the cycle and is often felt in one specific area. Causes include:

a cyst or a benign lump;
breastfeeding problems such as mastitis or a blocked duct – see breastfeeding after breast surgery;
pain from the chest wall: strained muscles, rib cartilage inflammation (costochondritis) or posture;
a poorly fitting bra, especially with large, heavy breasts;
after breast surgery, nerve regeneration or, with implants, capsular contracture;
certain medicines, including some antidepressants.

When is breast pain a warning sign?

See your doctor promptly if the pain:

is new, in one specific spot and does not go away after your next period;
comes with a lump, skin dimpling, nipple changes or discharge;
comes with redness, warmth and swelling, or a fever (possible infection or, rarely, inflammatory breast cancer);
appears after the menopause without an obvious reason;
wakes you at night or keeps getting worse.

The checks are the same as for a lump: examination, ultrasound and/or mammography. Our page on breast cancer symptoms lists the signs to watch.

Relief for breast pain

A well-fitting, supportive bra – professionally measured – during the day, and a soft sports or sleep bra at night when pain is cyclical.
A good sports bra for exercise.
Pain relief: simple painkillers, or anti-inflammatory gels applied to the breast, if suitable for you.
Keeping a pain diary for two or three cycles, which helps your doctor distinguish cyclical from non-cyclical pain.
Reviewing medication with your doctor if pain started with a new hormone treatment.

Evidence for supplements such as evening primrose oil is weak. Severe, persistent pain is sometimes treated with prescription medicines under specialist supervision.

Breast pain at different stages of life

Puberty: developing breasts are often tender, and one side may grow before the other. This is normal.

Pregnancy and breastfeeding: tenderness is one of the first signs of pregnancy. During breastfeeding, pain may come from engorgement, a poor latch, a blocked duct or mastitis; a midwife or lactation consultant can help, and a red, hot, painful area with fever needs prompt medical attention.

Perimenopause: fluctuating hormones can make cyclical pain worse for a few years before it settles.

After the menopause: breast pain is less common unless you take hormone replacement therapy, so new pain at this age is a good reason to see your doctor.

After breast surgery: after a breast lift, augmentation or reduction, aching and sharp "zings" as nerves recover are normal for weeks to months. Our recovery guide explains what to expect. Pain that suddenly increases, especially with swelling of one breast, should be reported to your surgeon straight away.

Heavy breasts, back pain and breast reduction

When pain comes from the sheer weight of very large breasts – aching shoulders and neck, back pain, deep bra-strap grooves, rashes under the breasts and difficulty exercising – the cause is mechanical. Physiotherapy and better bras help, but a breast reduction is the definitive solution for many women and often brings major relief. The operation removes tissue and lifts the breast at the same time; see also our page on breast lift surgery. New City Clinic explains the procedure on its breast reduction page.

Frequently asked questions

Is breast pain a sign of cancer?

Rarely on its own. Most breast pain is hormonal or from the chest wall. Pain with a lump, skin or nipple changes, or pain in one spot that persists should be checked.

Why do my breasts hurt before my period?

Hormone changes in the second half of the cycle make breast tissue retain fluid and become tender. It usually eases once the period starts.

Can a bra really make a difference?

Yes. Many women wear the wrong size; a properly fitted supportive bra often reduces both cyclical pain and pain from heavy breasts.

Can breast reduction cure back pain?

When back and neck pain are caused by heavy breasts, many women report significant improvement after a reduction. Other causes of back pain should be ruled out first.

Is breast pain normal after breast surgery?

Some discomfort, sensitivity and shooting nerve pains are normal for weeks or months. New pain with hardening of the breast or swelling should be checked by your surgeon.

Can men have breast pain?

Yes, often due to gynecomastia, medicines or hormonal changes. A firm lump or nipple changes in a man should be examined.

Should I have a mammogram because of breast pain?

Not always. If your pain is cyclical and the examination is normal, imaging may not be needed. Localised, persistent pain, or pain with other changes, is usually investigated with ultrasound and, depending on your age, mammography. Your doctor will decide which test is appropriate.

Do diet and lifestyle affect breast pain?

Evidence is limited. Some women notice less tenderness when they reduce caffeine or saturated fat, stop smoking or exercise regularly. These changes are harmless to try, but they should not delay a medical check if you have warning signs.

Can breast pain be caused by stress?

Stress does not directly damage the breast, but it can make you more aware of pain and tension in the chest wall muscles. Relaxation, sleep and regular exercise help many women.
