And interrogation.

Breast needle examination is a medical examination method used to diagnose abnormal breast tissue, the main purpose of which is to take a sample of breast tissue or cells and further analyze its nature to determine whether it is a benign or malignant tumor. This test is often recommended by doctors as an additional diagnostic tool after breast ultrasound or x-rays reveal abnormalities.

Common types of tests include:

• Fine needle extraction (FNA): Cell samples will be taken using a thin needle suitable for initial screening.
• Coarse needle sections (core biopsy): A thick needle is used to collect tissue samples and increase diagnostic accuracy.
• Vacuum Assist Section (VAB): Assist in the extraction of large tissue samples by vacuum equipment, suitable for testing small mineralization points.

According to the Hong Kong Breast Cancer Foundation, approximately 4,000 women are diagnosed with breast cancer each year, and breast aspiration screening plays a crucial role in early diagnosis.

Why do you need breast suction?

The main purpose of a breast needle examination is to check the nature of abnormal tissue in the breast. Needle removal may be required if:

• Look for lumps in the chest, especially those that feel hard or irregular when touched.
• Mammography and ultrasound examinations may show abnormalities such as calcification points and structural distortions.
• Distinguish between benign and malignant tumors to develop a follow-up treatment plan.

According to statistics from the Hong Kong Health Bureau, about 80% of breast lumps are benign, but malignant lesions can be detected early by needle sampling, which improves the success rate of treatment.抽針

Preparation before pulling the needle

Before undergoing a breast needle examination, the patient should prepare:

• Consult your doctor: Understand the inspection process, potential risks and benefits, and be mentally prepared.
• Inform your doctor: Please provide information such as any medications you are taking (e.g., anticoagulants) and allergy history (e.g., anesthetic allergy).
• Precautions: You may need to stop taking certain medications (such as aspirin) and avoid dietary restrictions before the test (some tests require fasting).

The doctor may recommend that the patient undergo a breast ultrasound before the examination to determine the location and size of the lump, thereby improving the accuracy of needle extraction.乳房 超聲波 檢查

The process of removing the needle

The process of a breast needle examination usually involves the following steps:

• Disinfection and anesthesia: First, the examination area is disinfected and a local anesthetic is injected to reduce discomfort.
• Needle Removal Procedure: Depending on the type of test, the doctor will use a thin, thick, or vacuum device to take the sample.
• unhappy: There may be a slight tingling or pressure sensation in the process, but most patients can tolerate it.

The examination usually lasts from 30 minutes to 1 hour, depending on the complexity of the lump.

Care and precautions after needle removal

After the examination, the patient should pay attention to:

• Wound care: Keep the wound clean and dry to avoid infection.
• Pain management: You can use pain relievers or ice to relieve mild pain.
• Observe anomalies: If you notice abnormal bleeding, redness, swelling, or fever in the wound, seek immediate medical attention.

Most patients can return to normal activities within 1-2 days, but strenuous exercise should be avoided.

Interpretation of needle draw results

The results of the examination are usually divided into the following categories:

• Benign results: Common benign tumors include fibroadenomas or cysts.
• Malignant outcomes: If you are diagnosed with breast cancer, your doctor will discuss your follow-up treatment options (surgery, chemotherapy, etc.).
• Inconclusive results: Further tests (such as MRI or surgical biopsy) may be required.

According to the Hong Kong Cancer Registry, about 15% of needle sampling results require further confirmation.

Risks and Side Effects of Breast Suction

Needle tests are low risk, but you may experience the following side effects:

• Bleeding and bruising: Minor bleeding and bruising usually go away on its own.
• infect: In rare cases, infection may occur and antibiotic treatment may be required.
• False Negatives/False Positives: The test results may be wrong and must be combined with other diagnostic tools.

Frequently Asked Questions (FAQs)

• Does a needle test spread cancer cells?: Very rare, but modern technology has significantly reduced the risk.
• Does it hurt to take a needle and test it?: Under local anesthesia, most patients experience only mild discomfort.
• How long does it take for the report to arrive after the needle is drawn?A: It usually takes 3-7 working days.
