Specialist Explains Needle Biopsy Options for Diagnosing Breast Lumps
AM730 · 1 SOURCESabout 1 hour ago2 MIN
Summary
Breast cancer is the most common cancer among women in Hong Kong, and discovering a lump through self-examination often causes significant anxiety. Following imaging tests, a needle biopsy may be necessary to determine whether the mass is benign or malignant. General surgeon Dr. Ying Wai-leung has addressed common misconceptions about the two main biopsy techniques and emphasized that tissue biopsy has become the international standard for breast cancer diagnosis.
Key Points
- Dr. Ying Wai-leung, a specialist in general surgery, explains that the needle size difference between core and fine needle biopsy is minimal .
- Unlike common belief, fine needle aspiration without anesthesia can actually be more painful than core needle biopsy performed with local anesthetic .
- Tissue biopsy provides a higher diagnostic accuracy than cell examination because it retrieves an intact piece of tissue rather than individual cells .
- Cell examination may contain errors and cannot be used for subsequent genetic testing of tumor characteristics .
- Vacuum-assisted biopsy (VAB) uses suction to collect more breast tissue in one procedure, reducing risk and patient discomfort compared to repeated insertions .
- For benign tumors under 1 centimeter, VAB can perform minimally invasive removal without traditional surgical incisions .
- Women over 40 without family history should undergo mammography every two years; those with family history or genetic mutations require annual screening .
Why It Matters
With breast cancer being the leading cancer among Hong Kong women, understanding the most accurate diagnostic procedures helps patients avoid unnecessary repeat biopsies and ensures timely, appropriate treatment. Early detection through regular screening significantly improves prognosis, making it crucial for women to be aware of current medical standards and recommendations .
