Core needle biopsy


A core biopsy is used when the area of concern or lump is solid (that is, not fluid based) and a tissue sample is required. Like FNA, this still involves a needle but the needle is slightly thicker and is designed to take a core of tissue not fluid. To use this form of biopsy a slight nick will be made into the skin under local anaesthetic. The needle will again be guided to the area of concern or lump with ultrasound so the correct tissue is taken. The core biopsy is performed in the doctor’s or radiology rooms. As with any samples taken, they will be sent to the laboratory for analysis. A report is sent back to your doctor or specialist.
