Symptoms:

Symptoms may range from mild to severe. They typically peak before each menstrual period and improve immediately afterwards.

Symptoms include:

• Dense, irregular and bumpy "cobblestone" consistency in the breast tissue
  • Usually more noticeable in the outer upper part of the breast
• Breast discomfort
  • Usually in both breasts
  • May be persistent or it may come and go
• Breast feels full
• Dull, heavy pain and tenderness
• Premenstrual tenderness and swelling
• Occasional nipple discharge

Signs and tests:

The health care provider will perform a breast exam. A breast exam will reveal breast "masses" that move and change shape. The masses are usually rounded with smooth borders and may feel rubbery.

Mammograms may be difficult to interpret because of dense breast tissue. A breast ultrasound can help identify cystic changes in the breast. A biopsy of the breast may be necessary to rule out other problems.

Aspiration of the breast with a fine needle can often diagnose and treat larger cysts.
