A fluid-filled lump that forms within the milk-producing tissue of the breast. Breast cysts most commonly affect women in their 40s and 50s, especially in the years around the menopause. A lump can be diagnosed as a cyst by ultrasound scanning, a mammography, or by withdrawing fluid from it with a syringe and needle, which usually results in the lump disappearing. About half of all women who have a breast cyst will develop future cysts. Any new breast lump should be seen by a doctor to confirm the diagnosis.
