Detailed explanation-1: -The main advantages of FNA are that the skin doesn’t have to be cut, and in some cases it’s possible to make a diagnosis the same day. The disadvantage is that sometimes this needle can’t remove enough tissue for a definite diagnosis.

Detailed explanation-2: -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.

Detailed explanation-3: -To perform a fine needle aspiration biopsy, the doctor inserts a very thin, hollow needle through the skin and into the suspicious area. The syringe attached to the needle suctions out a small sample of cells and sometimes fluid. This procedure may also be called a fine needle biopsy or FNA.

Detailed explanation-4: -Punch biopsy. During a punch biopsy, a circular tool is used to remove a small section of your skin’s deeper layers.
