Breast biopsy is a medical procedure that involves the removal of a small sample of breast tissue for examination under a microscope. This procedure is typically done in order to investigate a suspicious lump or other abnormality in the breast.
There are several types of breast biopsy procedures available, each with their own advantages and disadvantages. Some of the most common types include fine needle biopsy, core needle biopsy, vacuum-assisted biopsy, stereotactic biopsy, ultrasound-guided biopsy, MRI-guided biopsy, and sentinel lymph node biopsy.
In this section, we will provide an overview of the breast biopsy procedure, including the different types of biopsies, why they are important, who should consider getting a breast biopsy, how to prepare for the procedure, what to expect during and after the procedure, potential risks and complications, and answers to frequently asked questions.
Why is Breast Biopsy Important?
Breast biopsy is an important procedure for detecting breast cancer and other abnormalities. It is typically performed when there is a suspicious lump or other breast changes that require further examination. The biopsy allows for a small sample of breast tissue to be removed and examined under a microscope to determine if there are any cancerous or pre-cancerous cells present.
Early detection of breast cancer is crucial for successful treatment outcomes. If abnormalities are not detected and treated early, the cancer can spread to other parts of the body, making it more difficult to treat. Breast biopsy can help to detect cancer in its early stages, allowing for more effective treatment options and a higher likelihood of survival.
Additionally, breast biopsy can provide valuable information for individuals who are at high risk for breast cancer, allowing for closer monitoring and proactive steps to reduce the risk of developing breast cancer.
Fine Needle Biopsy
A fine needle biopsy is a minimally invasive procedure used to obtain a small tissue sample from the breast for further examination. This type of biopsy is often used to investigate lumps or other abnormalities found during a breast exam or imaging test.
During the procedure, the patient will lie down on an exam table, and a healthcare professional will use a thin, hollow needle to extract a small amount of tissue from the breast. The needle is guided into the area of concern using ultrasound or mammography imaging.

After the procedure, the tissue sample will be sent to a laboratory for examination under a microscope. Results are typically available within a few days, and further treatment options will depend on the diagnosis.
What to Expect During a Fine Needle Biopsy
Before the procedure, the patient may be asked to change into a gown and remove any jewelry or clothing that could interfere with imaging. A local anesthetic will be administered to numb the area around the biopsy site, and the healthcare professional will use imaging technology to guide the needle into the breast tissue.
The procedure typically takes 20 to 30 minutes, and the patient may feel some pressure or discomfort as the needle is inserted and the tissue sample is obtained. Afterward, the patient will be given specific instructions on how to care for the biopsy site and what to watch for in terms of potential complications.
After the Procedure
After a fine needle biopsy, the patient may experience some mild pain or discomfort in the biopsy area. Ice packs or over-the-counter pain relievers may help alleviate these symptoms. It’s important for the patient to avoid strenuous activity and heavy lifting for a few days following the procedure to allow the biopsy site to heal properly.
The healthcare professional will provide further guidance on when to expect the results of the biopsy and when to follow up with a healthcare provider.
Core Needle Biopsy
A core needle biopsy is a procedure in which a small sample of breast tissue is removed with a hollow needle. This type of biopsy is typically performed when a lump or abnormality is detected during a mammogram or physical exam, but cannot be identified by touch or imaging alone.
How It’s Performed
During the procedure, the patient lies on their stomach or back, depending on the location of the lump. Local anesthesia is used to numb the area, and a small incision may be made to help guide the needle to the correct location.
The needle is then inserted into the breast tissue and rotated to obtain a small core of tissue, which is removed and sent to a laboratory for analysis. Multiple samples may be taken depending on the size and location of the lump.
What to Expect During and After the Procedure
During the procedure, patients may feel a slight pressure or discomfort, but it should not be painful. After the procedure, the area may be sore and may experience some bruising, but this usually subsides within a few days.
Results from a core needle biopsy can take several days to a week, and patients should follow up with their healthcare provider to discuss the results and any further treatment options.
| Pros | Cons |
|---|---|
| Less invasive than surgical biopsy | May not provide enough tissue for diagnosis |
| Lower risk of complications compared to surgical biopsy | May not be able to retrieve tissue from certain locations |
Vacuum-assisted Biopsy
In a vacuum-assisted biopsy, a small cut is made in the skin, and a probe attached to a vacuum device is inserted into the breast tissue. The probe rotates and uses suction to remove several tissue samples through the same small incision. This procedure is typically done using local anesthesia and takes about an hour.
The tissue samples are analyzed by a pathologist to determine if they are cancerous or not. Vacuum-assisted biopsy is often used when the abnormality is too small or difficult to reach with other biopsy methods.
What to Expect During the Procedure
Before the procedure, you will receive a local anesthetic to numb the area where the biopsy will be performed. The doctor will use ultrasound or mammogram images to guide the probe to the location of the abnormality. You may feel some pressure during the procedure, but it should not be painful.
After the biopsy, a small bandage will be placed over the incision site, and you may experience some bruising or swelling. You can usually resume normal activities within 24 hours after the procedure, but your doctor will provide specific instructions based on your situation.
| Advantages | Disadvantages |
|---|---|
|
|
Stereotactic Biopsy
A stereotactic biopsy is a type of breast biopsy that uses mammography to precisely locate the suspicious area in the breast. It is typically performed when mammography has detected a suspicious mass that cannot be felt during a physical exam.
To perform the procedure, the patient lies face-down on a table with a hole for the breast. The breast is compressed between two plates, and mammography is used to determine the exact location of the mass. A local anesthetic is then injected to numb the area, and a small incision is made in the skin.
| Step | Description |
|---|---|
| Step 1: | A small incision is made in the skin |
| Step 2: | A biopsy needle is inserted through the incision and guided to the site of the suspicious mass using mammography |
| Step 3: | A tissue sample is then removed for examination by a pathologist |
After the biopsy, a small marker may be placed in the breast to mark the location of the biopsy site for future reference or treatment. The incision is then closed with a small adhesive bandage or stitches, and the patient can usually return to normal activities within a day.
Like other breast biopsy procedures, there may be some discomfort during the stereotactic biopsy, but it is generally well-tolerated. Complications are rare, but can include bleeding, infection, or a collapsed lung if the biopsy is performed close to the chest wall. Your doctor will provide detailed instructions on how to prepare for the procedure and what to expect during and after the biopsy.
Ultrasound-guided Biopsy
An ultrasound-guided biopsy is a procedure performed to extract tissue samples from a breast abnormality using sound waves. This type of biopsy is commonly used to examine lumps that can be visualized on an ultrasound but are not visible on a mammogram.
During the procedure, the patient lies on their back with their arm raised above their head. The radiologist or other trained medical professional will apply a gel to the breast and then use an ultrasound probe to locate the abnormality.
Once the abnormality is identified, a small needle will be inserted to remove tissue samples. The samples are then sent to a laboratory for analysis to determine if any cancerous cells are present.
| Pros | Cons |
|---|---|
| Low risk of complications | May not always be able to reach certain areas of the breast |
| No radiation exposure | May require multiple biopsies to obtain sufficient tissue samples |
An ultrasound-guided biopsy is a relatively quick procedure and typically takes less than an hour to complete. Patients may experience some mild discomfort, but overall, the procedure is considered to be safe and well-tolerated.
MRI-guided Biopsy
MRI-guided biopsy is a type of breast biopsy that uses magnetic resonance imaging (MRI) technology to guide the biopsy needle to the area of concern.
The MRI machine produces highly detailed images of the breast tissue, allowing the radiologist to precisely target the abnormal area for the biopsy. This type of biopsy is typically performed on suspicious areas that cannot be easily seen with other imaging techniques, such as mammography or ultrasound.
How is an MRI-guided biopsy performed?
Prior to the procedure, you will be instructed to remove any jewelry or clothing that may interfere with the MRI imaging. You will then lie face down on a specialized table that slides into the MRI machine.
During the biopsy, the radiologist will use the MRI images to guide a needle to the area of concern. Local anesthesia will be administered to numb the area before the needle is inserted through a small incision in the skin.
The radiologist will take multiple tissue samples using the biopsy needle, which will then be sent to a laboratory for examination. The procedure typically takes between 30 and 60 minutes to complete.
What can I expect after an MRI-guided biopsy?
After the procedure, you may experience bruising or swelling at the biopsy site. You will be advised to avoid activities that may cause excessive movement or stretching of the affected area, such as heavy lifting or exercise.
Results from the biopsy will typically be available within a few days. Your doctor will review the results with you and discuss any further treatment options if necessary.
Sentinel Lymph Node Biopsy
A sentinel lymph node biopsy is a type of biopsy that is used to determine if cancer cells have spread from the breast to the lymph nodes.
During a sentinel lymph node biopsy, a small amount of radioactive material and/or blue dye is injected near the tumor in the breast. The material then flows to the first lymph node(s) that drain the breast. These nodes are called sentinel nodes.
The surgeon then uses a special device to detect the radioactive material and/or blue dye and removes the sentinel nodes for examination under a microscope. If there are cancer cells in the sentinel nodes, it may indicate that the cancer has spread and further treatment may be needed.
This procedure is often used for patients who have early-stage breast cancer and a small tumor size.
| Advantages | Disadvantages |
|---|---|
| – Less invasive than traditional lymph node removal surgery | – Not always accurate in detecting cancer cells in lymph nodes |
| – Shorter recovery time compared to traditional lymph node removal surgery | – May still require further lymph node removal surgery if cancer cells are found |
Who Should Get a Breast Biopsy?
A breast biopsy may be recommended for individuals with suspicious lumps or other abnormalities in their breast tissue, or those who are at high risk for breast cancer. Your doctor may also recommend a biopsy if previous imaging tests have detected changes in your breast tissue.
It is important to note that not all breast abnormalities require a biopsy, and your doctor will take into account various factors when determining the best course of action for you. Factors such as your age, medical history, and family history of breast cancer may all influence whether a biopsy is recommended.
Preparing for a Breast Biopsy
Preparing for a breast biopsy is important to ensure that the procedure goes smoothly and that you are comfortable throughout. Here are some tips to help you prepare:
- Wear comfortable clothing that allows easy access to the breast area.
