Common Language Description

A percutaneous breast biopsy is a minimally invasive procedure that allows for the collection of tissue samples from breast lesions. This procedure is guided by ultrasound, which helps the physician accurately locate the lesion within the breast tissue. Initially, the skin over the biopsy site is cleansed to reduce the risk of infection, and a local anesthetic is administered to ensure patient comfort during the procedure. The use of ultrasound imaging is critical, as it provides real-time visualization of the lesion, allowing the radiologist to monitor the precise placement of the biopsy needle or device. During the biopsy, if a needle biopsy is performed, the physician inserts a specialized needle into the lesion to extract a tissue sample. Typically, multiple core needle insertions—ranging from three to six—are necessary to obtain sufficient tissue for accurate diagnosis. Alternatively, if an automated vacuum-assisted or rotating biopsy device is utilized, the procedure involves making a small incision in the skin and placing a breast probe at the lesion site. This device uses a vacuum mechanism to draw breast tissue into its sampling chamber, or a rotating cutting mechanism to capture tissue samples. The physician may rotate the probe approximately 30 degrees between samples, often obtaining between eight to ten samples to ensure a comprehensive evaluation of the lesion. To facilitate future surgical procedures, such as a lumpectomy, a metallic localization clip or pellet may be placed at the biopsy site. This clip serves as a marker for the surgeon, indicating the exact location of the tissue that has been biopsied. After the biopsy is completed, the needle is typically left in place while a plastic stylet with a metal clip or pellet is inserted through the needle and guided to the biopsy site using ultrasound. Once positioned, the clip or pellet is released, and both the stylet and needle are removed. Additionally, imaging of the biopsy specimen may be performed to assist in the pathological examination of the collected tissue, ensuring that the samples are suitable for further analysis.

1. Indications

The percutaneous breast biopsy procedure is indicated for the evaluation of breast lesions that may be suspicious for malignancy or other pathological conditions. The following conditions may warrant this procedure:

  • Suspicious Breast Lesion Lesions identified through imaging studies, such as mammograms or ultrasounds, that exhibit characteristics suggestive of cancer.
  • Palpable Mass A mass that can be felt during a physical examination, which may require histological evaluation to determine its nature.
  • Follow-Up of Previous Findings Lesions that have shown changes over time in previous imaging studies, necessitating further investigation.

2. Procedure

The procedure for a percutaneous breast biopsy involves several critical steps to ensure accurate tissue sampling and patient safety. The following outlines the procedural steps:

  • Preparation The skin over the biopsy site is thoroughly cleansed with an antiseptic solution to minimize the risk of infection. A local anesthetic is then injected to numb the area, ensuring the patient remains comfortable throughout the procedure.
  • Ultrasound Guidance A transducer is utilized to visualize the lesion in real-time. The radiologist carefully monitors the placement of the biopsy needle or device using the ultrasound images, ensuring precise targeting of the lesion.
  • Needle Biopsy If a needle biopsy is performed, the physician inserts a specialized biopsy needle into the lesion to obtain a tissue sample. This may require multiple insertions, typically between three to six, to gather an adequate amount of tissue for analysis.
  • Automated Vacuum-Assisted or Rotating Biopsy In cases where an automated device is used, a small incision is made, and a breast probe is placed at the lesion site. The device either draws tissue into a sampling chamber via a vacuum or uses a rotating mechanism to cut and capture tissue samples. The physician rotates the probe approximately 30 degrees between samples, often collecting eight to ten samples to ensure comprehensive evaluation.
  • Placement of Localization Device After obtaining the necessary tissue samples, a metallic localization clip or pellet may be placed at the biopsy site. This is particularly important if a subsequent surgical procedure, such as a lumpectomy, is anticipated. The clip serves as a marker for the surgeon to identify the exact location of the biopsy.
  • Completion of the Procedure Once the sampling is complete, the biopsy needle is typically left in place while a plastic stylet with a metal clip or pellet is inserted through the needle. Using ultrasound guidance, the clip or pellet is positioned at the biopsy site and released. Finally, both the stylet and needle are removed, and pressure is applied to the biopsy site to control any bleeding.

3. Post-Procedure

After the percutaneous breast biopsy, patients are typically monitored for a short period to ensure there are no immediate complications, such as excessive bleeding or adverse reactions to the anesthetic. It is common for patients to experience some discomfort or bruising at the biopsy site, which usually resolves within a few days. Patients are advised to avoid strenuous activities and heavy lifting for a short period following the procedure to promote healing. Additionally, follow-up appointments may be scheduled to discuss the biopsy results and any further necessary actions based on the findings. If imaging of the biopsy specimen is performed, this may also be reviewed during the follow-up visit to ensure the samples are suitable for pathological examination.
