Mastodynia, mastalgia or mammalgia are names for a medical symptom that means breast pain (from the Greek masto-, breast and algos, pain).

Pain can range from minor discomfort to severely incapacitating pain. Many women are more worried about a possible cancer risk than about the pain.

Breast pain during lactation or after weaning is not included into this definition but usually classified as breast engorgement or mastitis.



It can be classified into 2 main clinical patterns:

  • cyclical when the pain intensity is changing during the menstrual cycle.
  • non-cyclical when the pain remains essentially unchanged during the menstrual cycle. This type is less frequent.


Cyclical breast pain (cyclical mastalgia) is very often associated with fibrocystic breast changes or duct ectasia and believed to be caused by aberrations in dynamic hormonal changes mainly involving prolactin response to thyrotropin. [1] [2] Some degree of cyclical breast tenderness is normal in the menstrual cycle, and is usually associated with menstruation and/or premenstrual syndrome (PMS).[3]

Noncyclical breast pain has various causes and is harder to diagnose. Noncyclical pain has frequently its root cause outside the breast. Some degree of non-cyclical breast tenderness can normally be present due to hormonal changes in puberty (both in girls and boys), in menopause and during pregnancy.[3] After pregnancy, breast pain can be caused by breastfeeding.[3] Other causes of non-cyclical breast pain include alcoholism with liver damage (likely due to abnormal steroid metabolism), mastitis and medications such as digitalis, methyldopa (an antihypertensive), spironolactone, certain diuretics, oxymetholone (an anabolic steroid), and chlorpromazine (a typical antipsychotic).[3] Also, shingles can cause a painful blistering rash on the skin of the breasts.[3]

Treatments for cyclical breast pain

While in many cases it would possible to predict which treatment will be most effective with a series of endocrinological investigations involving thyroid and complicated pituitary hormone testing [4], this is rarely done in practice.

Treatments which demonstrated some effectiveness:

  • Vitex agnus-castus extract: there is convincing evidence that Vitex agnus castus is safe and efficient in the treatment of cyclical mastalgia. It is assumed, that like bromocriptine it works by reducing prolactin secretion from the pituitary gland. [5]
  • Topical and systemic NSAIDs, analgesics
  • Progestin based birth control pills or topical progesterone application. This method is effective only in a minority of women but is often tried because of its well known safety profile. Cyclic progestin on days 14-25 did show promising results.[6]
  • Dopamine agonists, best results with a better side effect profile than bromocriptine can be achieved with Dostinex.[7]The older bromocriptine has been found very efficient with relatively good safety, is however associated with many unpleasant adverse side effects. [8] There is very little although promising data on lisuride[9] and quinagolide.[10]
  • Iodine: supplementation with supraphysiologic levels of iodine has been shown effective in the treatment of breast pain. Not yet widely recommended until the long term effects of supraphysiologic doses of iodine on thyroid health are better understood. [11] [12]
  • Danazol: low dose danazol treatment has been found very efficient with modest side effects. The lowest dose tested in one trial produced the most favorable long term results and was associated with least adverse effects.[13]
  • Thyroid hormone supplementation, especially when hypothyroidism or subclinical hypothyroidism has been diagnosed. However even levothyroxin supplementation in normal patients has been shown effective. [14]
  • Tamoxifen has been shown effective but is very rarely used because of serious concerns about safety in premenopausal women.
  • Anthocyanins from bilberry.[15]

Treatments for non-cyclical breast pain

Determining the appropriate treatment for noncyclical breast pain is more difficult, not only because it is hard to pinpoint where the pain is coming from, but also because the pain may not have hormonal causes and very often does not respond to hormonal treatment.

Breast cancer risk

Great majority of breast cancer cases do not present with symptoms of pain.

Some epidemiological investigations suggest that women with symptoms of breast pain may have an increased risk of subsequently developing breast cancer and risk increases with duration of symptoms. [16] This is consistent with the observation that a few special subtypes of fibrocystic breast changes exhibit increased breast cancer risk – see breast cancer risk of fibrocystic breast changes.
