Breast needle biopsy is the removal of a sample of breast tissue using a needle. The sample is examined in a lab. There are different types of breast needle biopsies:
Reasons for Procedure TOP
Breast needle biopsy is done to examine a suspicious area in the breast. It may be done if any of the following are found:
The biopsy can identify the area as either benign (noncancerous) or malignant (cancerous).
Possible Complications TOP

Leading up to the biopsy:
You may receive local anesthesia. If this is the case, the area that is being operated on will be numbed.
Description of the Procedure
The doctor will choose from several types of biopsies to get a tissue sample:
The skin over the area will be cleaned. A small needle will be inserted into the breast tissue. Fluid and/or tissue will be removed. The needle may be removed and re-inserted more than one time. After this is done, the doctor will apply pressure to the area and cover the spot with a bandage.
An ultrasound device is used to locate the area where the biopsy needs to be taken. After the location is found, a small needle will be inserted in the breast tissue. Samples of fluid and/or tissue will be removed. A bandage will be applied after the needle is removed.
The doctor may have you lie down on your stomach or sit depending on the equipment being used. Mammogram or ultrasound images will be taken to locate the suspicious area. The doctor will make a tiny cut in your breast and insert a special probe. Using the probe, the doctor will remove several core samples of breast tissue from the area. After this is done, the area will be covered with a bandage.
In some instances, the suspicious area can only be seen using an MRI. Because of this, an MRI-guided breast biopsy may be needed. This procedure takes more time. Tell your doctor if you have a cardiac pacemaker. It may affect the procedure.
How Long Will It Take?
It will take less than one hour. After the procedure, the tissue collected will be sent to a pathologist who will look at it under a microscope. It may take about 2-5 days to receive the test results.
Will It Hurt?
There will be slight pain in your breast after the biopsy. Your doctor may prescribe pain medication.
When you return home after the procedure, do the following to help ensure a smooth recovery:
