How accurate is a fine needle aspiration biopsy?

Why do I need a core needle biopsy?

If other tests show you might have breast cancer, your doctor might refer you for a core needle biopsy (CNB). This is often the preferred type of biopsy if breast cancer is suspected, because it removes more breast tissue than a fine needle aspiration (FNA), and it doesn’t require surgery.

What is the difference between fine needle aspiration and core biopsy?

Fine needle aspiration is only used for lumps that can be felt (palpable masses). Although core needle biopsy is usually the first choice for palpable masses, fine needle aspiration is sometimes done as a quick way to sample a breast lump felt during a clinical breast exam.

Does a core needle biopsy hurt?

For the most part, women who undergo image-guided core-needle breast biopsies experience minimal pain. Most patients report minimal pain during imaging-guided core-needle breast biopsies, according to a study published in the Journal of the American College of Radiology.
