Mastodynia, or breast pain, affects up to two thirds of women of childbearing age and is a frequent reason for seeking medical advice. Although generally benign, these pains can considerably affect quality of life. In our Maghreb countries, where women’s health deserves particular attention, understanding these symptoms becomes essential in order to reassure women and offer them appropriate solutions.
Mastodynia, or breast pain: definition and manifestations
What is mastodynia?
In medical terms, “mastodynia” refers to any pain felt in the breasts. These pains can take a variety of forms: pulling sensations, burning, tightness, a feeling of heaviness, shooting pains or cramps. The intensity varies considerably from one woman to another, ranging from mild discomfort to disabling pain.
Mastodynia, or breast pain, may be:
- Unilateral: affecting one breast only
- Bilateral: affecting both breasts
- Diffuse: spreading across the whole breast
- Localised: concentrated in one specific area
Accompanying symptoms
These pains are often accompanied by other signs:
- Hypersensitivity to touch
- Swelling and a feeling of heaviness
- Increased visibility of the superficial veins
- Discomfort even from the touch of clothing
- Possible radiating pain as far as the armpits
Causes of mastodynia, or breast pain
Hormonal factors: the main cause
Mastodynia, or breast pain, is closely linked to hormonal fluctuations. During the menstrual cycle:
- Oestrogens cause breast tissue to grow and increase vascular permeability
- Progesterone tempers some of the effects of oestrogens
- An imbalance between these hormones leads to congestion and pain
These pains typically appear a few days before menstruation and generally disappear when it arrives or shortly afterwards.
Taking hormonal contraception (the pill, an implant, a hormonal coil) can cause mastodynia, or breast pain. These symptoms often signal an unsuitable dose requiring a medical adjustment.
Mastodynia is frequently the first sign of pregnancy, even before a missed period. During breastfeeding, several factors contribute to the pain:
- Breasts engorged with milk
- Irritation of the nipples
- Cracked skin and inflammation
- The baby learning to latch on
The premenopausal period
In one woman in two, intense mastodynia appears before the menopause. The signs can be dramatic:
- Breast enlargement of up to two bra sizes
- Redness and heat in the breasts
- Very visible veins
- Throbbing pain lasting over long periods
These symptoms often point to fibrocystic disease, characterised by the development of cysts and nodules that are generally benign.
Other causes of mastodynia, or breast pain
- Breast cysts: benign fluid-filled masses
- Fibroadenomas: benign tumours, common in young women
- Fibrocystic dystrophy: a benign change in the breast tissue
- Mastitis: an infection affecting breastfeeding women in particular
- Large breasts: strain placed on the Cooper’s ligaments
- An unsuitable bra: compression or lack of support
- Intense sporting activity without appropriate protection
Some pains radiate towards the breasts without originating there:
- Intercostal or spinal neuralgia
- Muscular pain in the pectorals
- Venous circulatory disorders
How common is mastodynia, or breast pain?
International data
The statistics reveal the scale of the phenomenon: in a population of 1,048 sub-Saharan African women seen in hospital consultations, 16% had breast pain, of which 13% was non-cyclical and 3% cyclical.
In the United States, a study of 1,659 women reports a mastodynia prevalence of 51.5%. More telling still, 10% of women report having had breast pain for more than 50% of their lives.
Breakdown by age
Prevalence varies with age:
| Age group | Prevalence of mastodynia |
|---|---|
| Before 20 | 40% |
| Between 40 and 50 | 65% (peak) |
| After 60 | Back down to 40% |
This distribution confirms the close link with female hormonal activity.
Mastodynia and breast cancer: a legitimate concern
The statistical reality
One of the main fears among women with mastodynia, or breast pain, concerns the risk of cancer. The data are reassuring: out of 14,325 patients who underwent a full breast investigation, 5,841 (41%) complained of breast pain, but only 705 (5%) actually had cancer.
More precisely, among women with isolated pain and no clinical lump, one study finds:
- 86.5%: normal imaging results
- 8.6%: benign abnormalities
- 3.6%: probably benign abnormalities
- 0.8%: suspicious abnormalities
- 0.4%: confirmed cancer
Inflammatory cancer: the exception
Although the majority of breast cancers do not cause pain, inflammatory breast cancer (1 to 5% of breast cancers) may present with:
- Intense pain
- Redness and heat
- Breast oedema
- A “peau d’orange” (orange-peel) appearance
Diagnosing mastodynia, or breast pain
Clinical examination
The consultation begins with detailed questioning, exploring:
- The characteristics of the pain: location, intensity, duration
- Its relationship with the menstrual cycle
- Current treatments (contraception, hormones)
- Personal and family medical history
The physical examination includes careful palpation of the breasts, looking for masses, nodules or abnormally tender areas.
Assessment tools
It makes it possible to quantify the intensity of the pain objectively and to distinguish cyclical pain from non-cyclical pain.
This simple tool helps characterise cyclical mastodynia by recording the intensity of the pain each day over several cycles.
Further investigations
In the absence of a palpable abnormality, further investigations are generally not necessary. However, if suspicious signs are detected:
The reference examination after the age of 40, it shows the architecture of the breast and detects abnormalities.
Particularly useful in young women with dense breasts, it distinguishes solid masses from fluid-filled ones.
Not recommended if mammography and ultrasound are normal, it may be indicated in particular cases.
Treating mastodynia, or breast pain
First-line management
After a normal work-up, information and reassurance are often the most effective treatment. Explaining that the symptoms are benign is enough in many cases.
A well-fitted bra, offering optimal support without excessive compression, significantly improves comfort. For women with large breasts, a model with wide straps and side reinforcement is recommended.
Drug treatments
- Paracetamol: effective for moderate cyclical pain
- Non-steroidal anti-inflammatory drugs (NSAIDs): particularly useful applied locally (gels)
If simple measures fail:
- Topical progesterone: gels to be applied to the painful area
- Danazol: effective, but side effects need monitoring
- Tamoxifen: reserved for severe, resistant cases
Natural approaches
- Evening primrose oil: rich in essential fatty acids, it reduces the intensity of mastodynia
- Sage: hormone-balancing properties (contraindicated in case of a history of hormone-dependent cancer)
- Vitex: a natural regulator of the cycle
Several essential oils show some effectiveness:
- Bay laurel: anti-inflammatory and pain-relieving properties
- Juniper: decongestant action
- Clary sage: hormone-balancing
- Copaiba: a natural anti-inflammatory
- Cutting down on salt: limits water retention
- Reducing caffeine: may reduce breast sensitivity
- Regular physical activity: improves circulation
- Managing stress: relaxation techniques
