How to perform breast biopsy
Breast biopsy is a common medical test used to diagnose suspicious lumps or lesions in the breast. With the advancement of medical technology, this examination method is becoming more and more accurate, helping doctors to detect breast cancer or other breast diseases early. This article will introduce in detail the steps, precautions and related data of breast biopsy.
1. Overview of Breast Biopsy
Breast biopsy is to extract a small amount of cells or tissue samples from the breast tissue through a puncture needle and send it to the laboratory for pathological examination. According to different puncture methods, it can be divided into fine needle aspiration biopsy (FNA) and core needle biopsy (CNB). Here is a comparison of the two methods:
| Type | Applicable situations | Advantages | Disadvantages |
|---|---|---|---|
| Fine needle aspiration biopsy (FNA) | Used to extract cell samples and preliminary screening | Less trauma, faster recovery | Small sample size, may require a second biopsy |
| Core needle biopsy (CNB) | Used to extract tissue samples and confirm the nature of lesions | Larger sample size, more accurate results | Slightly larger trauma and longer recovery time |
2. Steps of Breast Biopsy
Breast biopsy usually involves the following steps:
1.Preoperative preparation: The doctor will use ultrasound or mammography (mammography) to locate the suspicious area and mark the puncture point.
2.local anesthesia: Inject anesthetic drugs at the puncture site to reduce pain.
3.puncture sampling: According to the inspection needs, use a fine needle or core needle to puncture and extract the sample.
4.Sample processing: Send the sample to the laboratory for pathological analysis.
5.Postoperative care: The puncture site needs to be bandaged with pressure to avoid bleeding or infection.
3. Precautions for Breast Biopsy
1.Before surgery: Avoid taking anticoagulant drugs and truthfully inform your doctor about your allergies and medical history.
2.intraoperatively: Stay relaxed and cooperate with the doctor.
3.After surgery: Observe whether there is redness, swelling, pain or heat at the puncture site, and seek medical treatment promptly.
4. Risks and complications of breast biopsy
Although breast biopsy is a relatively safe test, there may still be risks of:
| Risk type | probability of occurrence | Countermeasures |
|---|---|---|
| bleeding or hematoma | lower | Apply pressure bandage after surgery and avoid strenuous exercise |
| infection | rare | Keep the wound clean and use antibiotics if necessary |
| pain or discomfort | common | Usually relieved within 1-2 days, painkillers can be taken |
5. Applicable groups for breast biopsy
Breast biopsy is usually performed when:
1. Suspicious lumps are found during breast ultrasound or mammography.
2. Breast MRI shows abnormal signals.
3. Clinical symptoms such as nipple discharge or skin depression.
6. Postoperative recovery after breast biopsy
Most patients can return to normal activities 1-2 days after surgery, but please note the following:
1. Avoid strenuous exercise or heavy lifting.
2. Keep the puncture site dry to avoid infection.
3. Follow the doctor’s recommendations for review or further treatment.
7. Summary
Breast biopsy is an important means of diagnosing breast diseases and can help doctors detect breast cancer or other lesions early. Although there are certain risks, its accuracy and safety have been widely recognized. If you have breast concerns, it is recommended to seek medical treatment promptly and follow the advice of professional doctors.
