What causes breast cysts?
Fibrocystic breasts occur from changes in the glandular and stromal (connective) tissues of the breast. These changes are related to a woman’s menstrual cycle and the hormones, estrogen and progesterone. Women with fibrocystic breasts often have bilateral cyclic breast pain or tenderness that coincides with their menstrual cycles.





During each menstrual cycle, normal hormonal stimulation causes the breasts’ milk glands and ducts to enlarge, and in turn, the breasts may retain water. Before or during menstruation, the breasts may feel swollen, painful, tender, or lumpy. The severity of these symptoms varies significantly from woman to woman. Some women only experience mild breast swelling during menstruation, while others experience constant breast tenderness. Because the condition is hormone-related, it will usually affect both breasts (bilaterally). Symptoms of fibrocystic breasts usually stop after menopause but may be prolonged if a woman takes hormone replacement therapy.While having fibrocystic breasts is usually not a risk factor for breast cancer, the condition can sometimes make breast cancer more difficult to detect. Therefore, in some cases, breast imaging exams, such as mammography or ultrasound, will need to be performed on women who show symptoms of fibrocystic breasts. However, screening mammography may be more difficult to perform on women with fibrocystic breasts because the breast density associated with fibrocystic breasts may eclipse breast cancer on the mammogram film. In some cases, additional mammography or ultrasound imaging, followed by fine needle aspiration or biopsy, will be performed on women with fibrocystic breasts to determine whether breast cancer is present. Fine needle aspiration (to drain large, painful cysts) may also be performed by a physician help relieve some of the more severe symptoms of fibrocystic breast condition.

Reply:My girlfriend had it. Don't know what causes it, but if the docs say its not harmful, don't worry about it! It's really nothing.
Reply:Breast Cysts are caused by estrogen dominance (too much estrogen). Synthetic artificial chemicals in our environment mimic estrogens that encourage breast cysts to form. Avoid these chemicals to get rid of breast cysts.
