Fibrocystic breast changes are common, with up to 80% of women experiencing symptoms at some point in their life.
Fibrocystic breasts are harmless. They're not a disease, just a common change in breast tissue that a lot of women experience.

Symptoms
Pain or discomfort in both breasts that may come and go with your period, but may last through the whole month
Breasts that feel full, swollen, or heavy
Pain or discomfort under the arms
Breast lumps that change in size with the menstrual period
Exams and Tests If you are over 40, you should have a mammogram to screen for breast cancer. For women under 35, a breast ultrasound may be used to look more closely at breast tissue. You may need further tests if a lump was found during a breast exam or your mammogram result was abnormal.
How Are Fibrocystic Breasts Treated?
Evening primrose oil. This supplement may reduce breast pain. One study found EPO, used for 6 months, resulted in reduced breast pain. It can be bought from health stores, pharmacies, and online. If you are pregnant or hoping to become pregnant, Don't take Evening Primrose oil.
Vitamin E: In one study, the use of Vitamin E for 6 months reduced breast pain. In another study, Vitamin E reduced breast pain with a dose of 200 IU twice daily.
Decrease the fat in your diet: which may decrease breast pain or discomfort associated with fibrocystic breasts.
Use a heating pad or warm water bottle to relieve your discomfort.
Diclofenac sodium 1% gel (Voltaren Arthritis Pain) - available as an OTC arthritis medication; this can be used on the breast to provide pain relief.
Adjust birth control pills. If you take birth control pills, skipping the pill-free week or switching birth control methods may help with breast pain symptoms.
Wear a well-fitting bra or sports bra
