Detailed explanation-1: -During fine-needle aspiration, a long, thin needle is inserted into the suspicious area. A syringe is used to draw out fluid and cells for analysis.

Detailed explanation-2: -This type of needle biopsy uses a thin, hollow needle to draw cells from your body. Core needle biopsy. This type of needle biopsy uses a wider needle than does fine-needle aspiration. The needle used during a core needle biopsy is a hollow tube that allows the doctor to extract a sample of tissue for testing.

Detailed explanation-3: -For an excisional biopsy: A doctor will use a scalpel to remove the entire skin lesion, usually with some normal skin around it called “a margin.” If the skin lesion is large, your provider may remove only a piece of it. This is called an incisional biopsy.

Detailed explanation-4: -During a fine needle aspiration (FNA), a small amount of breast tissue or fluid is removed from a suspicious area with a thin, hollow needle and checked for cancer cells. This type of biopsy is sometimes an option if other tests show you might have breast cancer (although a core needle biopsy is often preferred).

Detailed explanation-5: -The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle.
