This is where a small needle is used in order to extract a sample for examination, after which the doctor may be able to make a diagnosis.

Through the use of a needle biopsy, an extraction can be made for the doctor to examine in order to assess the situation and make a diagnosis. A wide range of illnesses, diseases, and problems can be diagnosed through examination of tissues and fluids, including the presence of benign tumors or of cancerous tumors.
Most patients find that not only is the needle biopsy a less invasive method of extracting samples, but it is also less traumatic, uncomfortable, and painful than many other methods, such as surgical biopsy. In the case of a tumor, a very thin needle is used in the needle biopsy, and with this, a sample can be taken from the tumor to be examined to determine whether it is benign or malignant.

You may find that the needle has to be inserted a number of times during the biopsy procedure, and this could for a variety of reasons, from getting the right positioning to obtaining enough of a tissue sample.
