Needle biopsy involves

Needle biopsy involves

• A. Removing a lesion from the surface only
• B. Extracting blood from a vein
• C. Tissue from deep within the body obtained by inserting a biopsy needle through the skin
• D. Imaging deep organs with ultrasound

Answer: (C)

Needle biopsy is a procedure that collects tissue from deep inside the body by inserting a biopsy needle through the skin. This percutaneous approach lets clinicians obtain cells or small tissue cores for microscopic examination to diagnose tumors, infections, or other diseases without a large surgical incision. The sample type can be a fine-needle aspirate (cells) or a core biopsy (til tissue), and the needle path is often guided by ultrasound, CT, or palpation to reach the target lesion. This differs from removing a surface lesion, drawing blood from a vein, or using imaging alone.
