What is a fine needle biopsy?

To determine the nature of a disease, the best way is to take a biopsy for pathological examination, that is, take a piece of tissue from the suspected lesion, which is called a biopsy. There are many specific operation methods for biopsy, such as forceps or fine needle aspiration, which are two commonly used methods. In easily obtained locations, such as lesions on the body surface, cervix, etc., biopsy forceps are often used to directly bite off a small piece of tissue. In the lungs, those parts of the abdominal cavity that cannot be reached by biopsy forceps will choose fine needle aspiration to enter the lesion to obtain tissue. Another difference between the two is that the tissue obtained by fine needle biopsy is less than that obtained by biopsy forceps. Sometimes the tissue obtained may not be able to confirm the diagnosis, and it may be necessary to repeat it several times to finally confirm the diagnosis and avoid missed diagnosis or diagnosis. misdiagnosed.
