Comparison of the two types of needle biopsies from the Mayo center website. Notice that is suggests at the end of the first paragraph to ask your doctor to explain why one is being recommended over the other.
There are several breast biopsy procedures used to obtain a tissue sample from the breast. Your doctor may recommend a particular procedure based on the size, location and other characteristics of the breast abnormality. If it's not clear why you're having one type of biopsy instead of another, ask your doctor to explain the reasons in more detail.
Types of breast biopsy include:
Fine-needle aspiration biopsy. This is the simplest type of breast biopsy and may be used to evaluate a lump that can be felt during a clinical breast exam. For the procedure, you lie on a table. While steadying the lump with one hand, your doctor uses the other hand to direct a very fine needle one more slender than that used to obtain a blood sample into the lump. The needle is attached to a syringe that can collect a sample of cells or fluid from the lump. Fine-needle aspiration is a quick method to distinguish between a fluid-filled cyst and a solid mass and, possibly, to avoid a more invasive biopsy procedure. If, however, no fluid can be withdrawn and the mass doesn't resolve on its own, you may need further evaluation with a diagnostic mammogram or ultrasound or surgery to remove it.
Core needle biopsy. This type of breast biopsy may be used to assess a breast lump that's visible on a mammogram or ultrasound or that your doctor feels (palpates) during a clinical breast exam. A radiologist or surgeon uses a thin, hollow needle but not quite as thin as the needle used in fine-needle aspiration to remove tissue samples from the breast mass. Several samples, each about the size of a grain of rice, are collected and analyzed to identify features indicating the presence of disease. Imaging techniques, such as mammography, ultrasound or MRI, are often used to guide the positioning of the needle used in a core needle biopsy.
Stereotactic biopsy. This type of biopsy uses mammograms to pinpoint the location of suspicious areas within the breast. For this procedure, you generally lie facedown on a padded biopsy table with one of your breasts positioned in a hole in the table. You may need to remain in this position for 30 minutes to one hour. The table is raised several feet. The equipment used by the radiologist is positioned beneath the table. Your breast is firmly compressed between two plates while mammograms are taken to show the radiologist the exact location of the area for biopsy. A small incision about 1/4-inch long (about 6 millimeters) is made into your breast. The radiologist inserts either a needle or a vacuum-powered probe and removes several samples of tissue. The samples are sent to a laboratory for analysis.
Ultrasound-guided core needle biopsy. This type of core needle biopsy involves ultrasound an imaging method that uses high-frequency sound waves to produce precise images of structures within your body. During this procedure, you lie on your back on an ultrasound table. Using ultrasound, the radiologist locates the mass within your breast, makes a small incision to insert the needle and takes several core samples of tissue to be sent to a laboratory for analysis.
MRI-guided core needle biopsy. This type of core needle biopsy is done under guidance of MRI an imaging technique that captures multiple cross-sectional images of your breast and combines them, using a computer, to generate detailed, 3-D pictures. During this procedure you lie facedown on a padded scanning table. Your breasts fit into a hollow depression in the table. The MRI machine provides images that help determine the exact location for the biopsy. A small incision of about 1/4-inch long (about 6 millimeters) is made to allow the core needle to be inserted. Several samples of tissue are taken and sent to a laboratory for analysis.
