Mammography is a specific type of imaging that uses a low dose x-ray system for examination of the breasts. Mammography plays a central role in the detection of breast cancer because it can show changes in the breast up to two years before a patient or physician can feel them. Current guidelines from the U. Mammography is used to aid in the diagnosis of breast diseases in women. As with all x-ray examinations, mammograms provide valuable information about your health and play an important role in helping your doctor make an accurate diagnosis.
Prior to Stereotactic breast biopsy radiation exposure needle biopsy, you should report to your doctor all medications that you are taking, including herbal supplements, and if you have any allergies, especially to anesthesia. Raidation doctor may also order these tests if a lump was discovered during a physical exam.

A stereotactic breast biopsy is a procedure that uses mammography to precisely identify and biopsy an abnormality within the breast. This procedure will help determine whether you have breast cancer or any other abnormalities in your breast to be concerned about. A mammography is a special form of X-ray used on the breasts. Stereotactic breast biopsies use mammographic X-rays to locate and target the area of concern and to help guide the biopsy needle to a precise location.
This technique helps ensure that the area that is biopsied is the exact area where the abnormality was seen on the mammogram. A breast biopsy is typically done to investigate irregularities such as a lump in the breast. A breast lump may be cause for concern. However, according to Mayo Clinic , breast lumps are often benign noncancerous. A breast biopsy is typically done if your doctor becomes concerned following a mammogram or breast ultrasound. Your doctor may also order these tests if a lump was discovered during a physical exam.
A stereotactic breast biopsy is a relatively simple and low-risk procedure. However, it does carry these risks:. Be sure to tell your doctor so alternative biopsy methods can be considered. Complications from a biopsy are rare. The risks associated with the procedure are outweighed by the benefits of having potentially cancerous calcifications inspected. Remember, the quicker breast cancer is detected, the faster your treatment can begin.
Before your breast biopsy, tell your doctor about any allergies you have, especially any history of allergic reactions to anesthesia. Also, be sure to mention any medications you may be taking, including over-the-counter drugs such as aspirin or supplements.
During the test, you could be lying on your stomach for up to an hour. Talk to your doctor if you are concerned that will be a problem for you. You should avoid using any type of moisturizer on your breasts and remove all jewelry and any body piercings before the biopsy. You might be given a cold pack after the procedure to help with pain and inflammation. Wear a bra to help keep the cold pack in place. The table will rise several feet in the air so your radiologist can access your breast though the hole in the table.
They will then use two plates to firmly compress your breast. This allows them to get X-ray pictures of your breast and identify the abnormalities in the breast tissue.
After the proper images are taken, a small area of your breast will be injected with local anesthesia. Then the radiologist will make a small nick in your breast. A sample of breast tissue will be taken using a needle or a probe attached to a vacuum. Several small tissue samples will be removed and sent to a pathology laboratory for testing. After the samples are taken, the doctor or technician will apply pressure to the area to prevent bleeding and then cover the area with surgical tape to keep it closed and prevent infection.
The samples of your tissue will be sent to a pathology laboratory. It may take up to a week for them to be properly analyzed. This includes keeping it clean and changing the bandages to prevent infection.

Stereotactic breast biopsy radiation exposure. How Should I Prepare My Stereotactic Breast Biopsy?
Stereotactic breast biopsy uses mammography — a specific type of breast imaging that uses low-dose x-rays — to help locate a breast abnormality and remove a tissue sample for examination under a microscope. It's less invasive than surgical biopsy, leaves little to no scarring and can be an excellent way to evaluate calcium deposits or tiny masses that are not visible on ultrasound. Tell your doctor if there's a possibility you are pregnant.
Discuss any medications you're taking, including aspirin and herbal supplements, and whether you have any allergies — especially to anesthesia. You will be advised to stop taking aspirin, blood thinners, or particular herbal supplements which can increase your risk of bleeding for three to five days before your procedure.
Don't wear deodorant, talcum powder or lotion under your arms or on your breasts for your procedure as these may appear on the mammogram. Leave jewelry at home and wear loose, comfortable clothing.
You may be asked to wear a gown. Lumps or abnormalities in the breast are often detected by physical examination, mammography, or other imaging studies. However, it is not always possible to tell from these imaging tests whether a growth is benign or cancerous. A breast biopsy is performed to remove some cells from a suspicious area in the breast and examine them under a microscope to determine a diagnosis. Image-guided needle biopsy is not designed to remove the entire lesion but to obtain a small sample of the abnormality for further analysis.
Image-guided biopsy is performed by taking samples of an abnormality under some form of guidance such as ultrasound, MRI or mammography. In stereotactic breast biopsy , a special mammography machine uses x-rays to help guide the radiologist's biopsy equipment to the site of the imaging abnormality.
A stereotactic breast biopsy may be performed when a mammogram shows a breast abnormality such as:. Stereotactic breast biopsy is performed as a non-surgical method of assessing a breast abnormality.
You will be asked to remove some of your clothes and to wear a gown during the exam. You may also be asked to remove jewelry, removable dental appliances, eye-glasses and any metal objects or clothing that might interfere with the x-ray images. Women should always inform their physician if there is any possibility that they are pregnant.
Some procedures using image-guidance are typically not performed during pregnancy because radiation can be harmful to the fetus. You should not wear deodorant, powder, lotion or perfume under your arms or on your breasts on the day of the exam. Prior to a needle biopsy, you should report to your doctor all medications that you are taking, including herbal supplements, and if you have any allergies, especially to anesthesia. Your physician may advise you to stop taking aspirin, blood thinners, or certain herbal supplements for three to five days before your procedure to decrease your risk of bleeding.
Also, inform your doctor about recent illnesses or other medical conditions. The specialized mammography machine used in this procedure is similar to the mammography unit used to produce mammograms. A mammography unit is a rectangular box that houses the tube in which x-rays are produced.
The unit is used exclusively for x-ray exams of the breast, with special accessories that allow only the breast to be exposed to the x-rays. Attached to the unit is a device that holds and compresses the breast and positions it so images can be obtained at different angles. The table is then raised and the biopsy procedure is performed beneath the table. At other facilities, the procedure may be performed while you sit in a chair.
Other sterile equipment involved in this procedure includes syringes, sponges, forceps, scalpels and a specimen cup or microscope slide. A special digital mammography machine is used to perform a stereotactic breast biopsy.
In digital mammography, as in digital photography, film is replaced by electronic detectors. These convert x-rays into electrical signals, which are used to produce images of the breast that can be immediately seen on a computer screen.
Stereotactic mammography pinpoints the exact location of a breast abnormality by using computer analysis of x-rays taken from two different angles. Using the calculated computer coordinates, the radiologist inserts the needle through a small cut in the skin, then advances it into the lesion and removes tissue samples. The table is raised and the procedure is then performed beneath it.
If the machine is an upright system, you may be seated in front of the stereotactic mammography unit. Preliminary stereotactic mammogram images are taken and reviewed by the radiologist.
Once the radiologist identifies the abnormality on imaging, the computer will generate coordinate information and send it to the biopsy device. The radiologist then inserts the needle and advances it to the location of the abnormality using the mammogram and computer generated coordinates. Mammogram images are again obtained to confirm that the needle is within the lesion prior to sampling.
Tissue samples are then removed, generally using a vacuum-assisted device. Typically, three to twelve samples are obtained, depending on the device used. If calcium deposits calcifications are being sampled, an x-ray of the removed tissue will be obtained to document enough deposits were obtained for analysis under a microscope. Additional sampling may be needed if not enough calcifications are identified initially.
A small marker may be placed at the biopsy site so that it can be located in the future if necessary. Once the biopsy is complete, pressure will be applied to stop any bleeding and the opening in the skin is covered with a dressing. No sutures are needed. You will be awake during your biopsy and should have little discomfort.
Many women report little pain and no scarring on the breast. Some women find that the major discomfort of the procedure is from lying on their stomach for the length of the procedure, which can be reduced by strategically placed cushions. When you receive the local anesthetic to numb the skin, you will feel a pin prick from the needle followed by a mild stinging sensation from the local anesthetic. You will likely feel some pressure when the biopsy needle is inserted and during tissue sampling, which is normal.
As tissue samples are taken, you may hear clicks or buzzing sounds from the sampling instrument. These are normal. If you experience swelling and bruising following your biopsy, you may be instructed to take an over-the-counter pain reliever and to use a cold pack. Temporary bruising is normal.
If a marker is left inside the breast to mark the location of the biopsied lesion, it will cause no pain, disfigurement or harm. Biopsy markers are MRI compatible and will not cause metal detectors to alarm. You should avoid strenuous activity for at least 24 hours after the biopsy. A pathologist examines the removed specimen and makes a final diagnosis. Follow-up exams may be needed. If so, your doctor will explain why. Sometimes a follow-up exam is done because a potential abnormality needs further evaluation with additional views or a special imaging technique.
A follow-up exam may also be done to see if there has been any change in an abnormality over time. Follow-up exams are sometimes the best way to see if treatment is working or if an abnormality is stable or has changed. Breast biopsy procedures will occasionally miss a lesion or underestimate the extent of disease present.
If the diagnosis remains uncertain after a technically successful procedure, surgical biopsy will usually be necessary. Please type your comment or suggestion into the text box below.

A stereotactic breast biopsy may be performed when a mammogram shows a breast abnormality such as: a suspicious mass microcalcifications, which are a tiny cluster of small calcium deposits a distortion in the structure of the breast tissue an area of abnormal tissue change a new mass or area of calcium deposits in a previous surgery site.
Tissue sample is obtained using: A vacuum-assisted device VAD , a vacuum powered instrument that uses pressure to pull tissue into the needle. This instrument rotates positions and collects multiple tissue samples through one needle insertion. Mammography is a low-dose x-ray system designed to evaluate breast tissue.
Breast biopsies are usually done on an outpatient basis. The breast is compressed and held in position throughout the procedure. A very small nick is made in the skin at the site where the biopsy needle is to be inserted. After the sampling is complete, the needle will be removed from the breast. A final set of images will be taken. A mammogram may be performed to confirm that the marker is in the proper position. This procedure is usually completed within an hour. The area will become numb within a few seconds.
You must remain very still while the imaging and the biopsy are being performed. Benefits The procedure is less invasive than surgical biopsy, leaves little or no scarring and can be performed in less than an hour.
