Breast pain occurs more frequently in younger, premenopausal women, although women who are postmenopausal can experience breast pain, too.

About one in 10 women experiences moderate to severe breast pain that lasts more than five days a month.  There are cases where women can have severe breast pain that lasts throughout their entire menstrual cycles.

Breast pain is usually classed as either:

Cyclical breast pain - where the pain is related to periods. Typically, this occurs during the second half of the monthly cycle, getting worse in the days just before a period, OR
Non-cyclical breast pain - where the pain is not related to periods.

Symptoms of cyclical breast pain
For most women the symptoms are mild. However, in some women the pain can be severe and last longer, sometimes up to 1-2 weeks before a period.  The pain may normally ease up soon after a period starts. 
Typically, the pain affects both breasts. It is usually worst in the upper and outer part of the breast, and may travel to the inner part of the upper arm.
Quality of life too can be significantly affected. Physical activity such as jogging can make the pain worse.

Symptoms of non-cyclical breast pain
Breast pain may present itself all the time, or 'come and go' in a random way. This type of breast pain is usually not related to periods. It is quite prevalent in women over 40. The pain may be in just one breast. Further, it may be localized to one area of the breast. There are various presentations, such as
(a)Pain coming from the breast tissue itself in the absence of any lumps, tumours, or other abnormality being detected.(b)Pain coming or radiating from the chest wall under the breast rather than the breast itself. (c)Infection is a cause in a small number of cases. In many cases the cause is often not clear and further investigation is required.  As there are various causes it is best to see a doctor for a detailed assessment.

Breast pain alone rarely suggests that there is  breast cancer. However, if you do have unexplained breast pain, get checked by a qualified breast specialist. In case you feel any lump in a breast., do visit a doctor promptly.
