Fibrocystic breast disease, commonly called fibrocystic breasts or fibrocystic change, is a benign (noncancerous) condition in which a woman develops fluid-filled sacs, which develop in the breast tissue, are called breast cysts.
The condition is so common that more than half of women will develop fibrocystic breast disease at some point in their lives.
Most cysts go away by themselves and are nothing to worry about.
If the cyst is large or causing discomfort, your specialist may draw off the fluid using a fine needle and syringe. Sometimes this is done using ultrasound to help find the cyst. The fluid drawn off from the cyst can vary in colour and range from clear to very dark. It will only be sent to a laboratory for testing if the fluid is bloodstained.
