Frequently Asked Questions
Why is This Exam Done?
The Ultrasound will show whether the lump is a fluid-filled cyst or a solid lump. It also shows whether a cyst is a “simple cyst” or “complex cyst.” An Ultrasound Guided Cyst Aspiration will remove fluid from inside a lump.
How Does it Work?
Ultrasound uses high-frequency sound waves to produce images of the body’s tissues, structures, and blood flow. A transducer/probe and ultrasound gel work in combination to absorb the reflected sound waves to produce images on the monitor.
What Will Happen During the Exam?
- A specially trained Radiologist will perform the procedure assisted by a Sonographer or Mammographer
- You may be asked to remove any clothing from the area having the procedure and change into a gown
- Warm gel will be applied to the area and the ultrasound transducer/probe will be moved on the area to locate the cyst
- The area will be cleansed and numbed with a local anesthetic which initially may cause a slight sting. Your breast will become numb within a short time.
- A thin needle will be inserted and then guided into the cyst with the ultrasound
- Fluid will be drained into a syringe
- Depending on the appearance, the fluid will either be discarded or sent to the laboratory for analysis
- Pressure will be applied to the procedure site for a few minutes, a bandage applied and cold/ice packs provided
- If the aspiration is in the breast, you may have a mammogram with limited compression to ensure that the cyst is gone
- Post procedure instructions will be provided
How Should I Prepare?
- There are no diet restrictions, eat and drink as usual
- You may perform normal daily activities prior to the procedure
- Take usual medications on exam day unless asked not to
- Aspirin and anticoagulants increase the risk of bleeding and bruising
- Patients taking anticoagulants (blood-thinners) or aspirin may be asked to stop using them for a few days prior to the procedure
- Herbal substances that affect bleeding, such as Gingko biloba, should be stopped prior to the breast biopsy
What Are the Benefits and Risks?
The benefits of Breast Biopsy (Fine Needle Aspiration):
- Can verify that the cyst is a simple cyst- fluid-filled sacs
- Removal of fluid will provide relief for painful cysts
Risks you should be aware of:
- Bleeding – unusual
- Hematoma, or a collection of blood at the biopsy site can occur. Less than 1% of patients.
- Bruising – resolves within a few weeks
- Infection – Any procedure where the skin is penetrated carries a risk of infection. Less than 1 in 1,000 patients.
- Cysts may recur after the aspiration
