Breast Cyst Aspiration
If the ultrasound shows that the breast cyst is a “simple cyst” it can be safely watched. No immediate action is necessary.
Many cysts will resolve if left alone. Cysts are not precancerous, do not turn into cancer, and do not put women at higher risk for breast cancer.
Simple cysts are not usually aspirated or “drained” unless they are very large in size, or are painful. Cysts that are not considered “simple” cysts by ultrasound usually need drainage or biopsy.
How is it performed?
You will be placed either on your back or turned slightly to the side while the ultrasound probe is used to locate the cyst. A local anesthetic is injected to be sure that you will feel no discomfort during the procedure. The radiologist will constantly monitor the cyst with ultrasound and guide a small needle directly into the cyst and remove fluid.
Will the fluid be sent to a lab for evaluation?
Normal breast cyst fluid can be yellow, green, or gray. Studies show that analysis of breast cyst fluid is of no value unless the fluid is bloody. If your breast cyst fluid shows signs of blood, then it should be sent to the laboratory for evaluation.
