Overview
Mastalgia is usually a benign disorder in young women due to hormonal imbalance during their menstrual cycle. During a menstrual cycle the breasts swell and become lumpy and tender. During a period, the breasts reabsorb the extra fluid inside instead of discharging it, causing breast pain. A breast exam and a breast ultrasound should be performed to make sure nothing is hidden.
Classification
Breast pain can be categorized into 2 main clinical patterns, cyclical and non cyclical.
Treatment
Prevention
There is not really any way to prevent most breast pain, but wearing a well-fitting bra for support may help.

Overview
Breast pain can be categorized into 2 main clinical patterns, cyclical and non cyclical.
Classification
It can be subdivided into 2 main clinical patterns:
- Cyclical when the pain is worse prior to each menstrual cycle
- This may occur with a woman’s natural menstrual cycles and is not due to any hormone or breast disease.
- It may be caused by use of hormonal contraception.
- Non-cyclical when the pain is unrelated to periods.
- It may be related to the underlying muscle.
- Trauma and resulting hematoma
- Infection is sometimes responsible, particularly during times of breast feeding.
- Breast engorgement during breast feeding (mastitis)
- Arthritis pain in the chest or neck felt as if it is coming from the breast.

Pathophysiology
Associated Conditions
- Breast cancer is, in 19 out of 20 cases, normally not painful in the early stages. New onset of a painless lump should therefore be promptly assessed.

Overview
Two thirds of breast pains are cyclical and one third have non cyclical cause.[1]
Cyclical breast pain 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. Some degree of cyclical breast tenderness is normal in the menstrual cycle, and is usually associated with menstruation and/or premenstrual syndrome (PMS).
Noncyclical breast pain has various causes and is harder to diagnose.It is more likely to be unilateral and variable in its location in 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, during pregnancy and breastfeeding. Other causes of non-cyclical breast pain include alcoholism with liver damage (likely due to abnormal steroid metabolism), mastitis, shingles and some medications.

Epidemiology and Demographics
- Most common breast symptom leading to office visit
- More common in premenopausal women
- Rarely a presenting symptom of cancer
- Study of women with known breast cancer: 7% presented with mastalgia alone.
- Women referred for mammogram because of mastalgia:
- 0.4% had breast cancer (same as controls)
- 87% had normal mammogram
- 9% had benign abnormalities
