Question:

Question:

What are the key factors in determining aspiration versus biopsy? Is it based on the needle used, or is it based on pulling fluid versus tissue?   

Answer:

Answer:

The difference is technique: Is the physician removing a piece (core) of tissue or suctioning / aspirating out cells or fluid? Another thing to consider is where the material is being sent. If it’s for cytology, chances are that it is aspiration; if histology, then it would be a core biopsy.
