What is a breast cyst?
A breast cyst is a fluid-filled pouch that may develop in women's breasts.
Are breast cysts usually cancerous?
No. Although breast cysts may cause discomfort, they are usually not cancerous.
Why is breast cyst aspiration performed?
Breast cyst aspiration, which is the draining of the cyst, is usually performed to determine whether or not the cyst is cancerous. In many cases, the cyst collapses upon aspiration.
Is breast cyst aspiration safe?
Breast cyst aspiration is a safe procedure, with no associated risks. Radiation is not used during the procedure.
How does a patient prepare for breast cyst aspiration?
There is no special preparation for breast cyst aspiration.
How is breast cyst aspiration performed?
Breast cyst aspiration is performed as an outpatient procedure with local anesthetic. Fine-needle aspiration and ultrasound-guided aspiration are two ways of performing the procedure. Both involve inserting a needle into the cyst to drain it; an ultrasound-guided procedure adds ultrasound to help guide the needle. Regardless of which is used, the patient may experience mild discomfort.
What happens at the end of the breast cyst aspiration procedure?
At the end of the breast cyst aspiration procedure, bandages and an ice pack are applied to the site of the aspiration, and the patient returns home. The area may feel numb until the anesthetic wears off, but that usually happens quickly. Normal activities can be resumed the next day.
How accurate are the results from breast cyst aspiration?
A breast-cyst aspiration provides accurate results about 80 percent of the time.
When are the results of breast cyst aspiration usually available?
Results are often available immediately after the procedure. When the fluid drained from a cyst is watery and does not contain blood, and the cyst goes away after the fluid is removed, it means that the cyst is not cancerous. If the fluid appears bloody, a sample is sent to a lab for further testing; results are usually available in a few days.
Is follow-up required after breast cyst aspiration?
Yes. Even if the cyst is successfully drained, 4 to 6 weeks later it is checked to make sure it has not refilled with fluid. If it has, surgical removal may be necessary.
