Cyst Aspiration and Biopsies

Stereotactic Biopsies


A stereotactic biopsy uses mammography, a special breast x-ray, to guide doctors to a lump or abnormality that can’t be felt or seen on ultrasound, but that can be seen on the mammogram. It creates a 3-D picture of the lump’s location to guide the radiologist to the right area with maximum accuracy.

During this procedure, you will lie face down on a special table that allows your breast to be placed in an opening. The radiologist will raise the table and perform a core needle or vacuum assisted biopsy from under the table. Your breast will be somewhat compressed during the procedure.

All of our Breast Biopsy facilities are ACR Accredited.


MRI-Guided Biopsies


As with the biopsies noted above, the MRI-guided biopsy uses MRI to guide the radiologist to the exact location of the lump. MRI biopsy is usually used when the lump can be seen on breast MRI, but cannot be readily seen on mammogram or ultrasound. The procedure is similar to those described above.

Vacuum-Assisted Biopsies


Vacuum-assisted biopsy devices are used for stereotactic and MRI guided biopsy and selected ultrasound guided biopsies. The device is a special probe that applies suction and allows retrieval of more tissue. Breast tissue is drawn into the sampling chamber of the probe with the vacuum and then cut. Several pieces of tissue are always obtained during biopsies, regardless of the type of needle used.

As with the other biopsies described here, after the procedure, you should experience minimal discomfort and no scarring, and you may resume normal activities.

Core Needle Biopsy


In a core needle biopsy, the radiologist locates the lump or abnormality that can be seen on a mammogram, sonogram or MRI. A hollow core needle is then placed inside the abnormality. The needle will then withdraw a small amount of tissue that will be sent to a lab for analysis. Prior to the procedure, you will be given some local anesthetic similar to the anesthetic used for dental procedures to numb the area. You may feel some pressure and mild discomfort but most patients do not feel pain. The doctor will insert the needle several times to get adequate tissue samples. After the procedure, you can resume normal activities immediately. You may experience some slight bruising but should not have a scar. It may take several days to one week to obtain results from the lab.
