Breast Cyst Aspiration

If a breast ultrasound confirms the presence of a fluid filled area (cyst), a breast cyst aspiration procedure may be performed. Some cysts can be quite tender and aspirating them (removing the fluid) may alleviate symptoms. Also, a large cyst may limit visualization of breast tissue and may need to be drained to allow optimal mammographic interpretation. Occasionally, cyst aspiration is needed to confirm that an abnormality found on an ultrasound examination is in fact a fluid filled cyst.

Most patients experience little discomfort with this procedure. The breast is numbed with a local anesthetic injection (usually Lidocaine). To precisely locate the cyst, a radiologist uses ultrasound imaging and/or your mammogram films to guide the placement of a hollow needle into the cyst to withdraw the fluid inside of it. After the aspiration, you will be able to resume your usual activities.

How to prepare for breast cyst aspiration

If you are taking Coumadin, or any other anti-coagulants or blood thinners, consult with your healthcare provider before scheduling this procedure. It is generally advised to stop these medications for three to five days before this procedure to avoid excessive bleeding.

To avoid delay or rescheduling of your cyst aspiration

Arrive 15 minutes before your scheduled appointment time to register. Plan for an additional one hour to complete your procedure.
