What procedure is performed by an AGACNP to evaluate cytology in a tumor?

The fine needle biopsy is the preferred procedure for evaluating cytology in a tumor due to its minimally invasive nature and ability to provide quick results. This procedure involves using a thin, hollow needle to extract cells from the suspicious tumor site. The sample obtained can then be examined under a microscope to determine the presence of cancer cells and to help classify the type of tumor.

This technique is particularly valuable for lesions that are accessible and can yield sufficient cellular material for cytological analysis. It is commonly used because of its reduced complication rates and the fact that it often does not require general anesthesia, making it suitable for patients who may not tolerate more invasive approaches.

While core needle biopsies and surgical excisional biopsies are also methods used to obtain tissue samples, they typically provide more extensive tissue samples for histological evaluation rather than focusing primarily on cytology. Computed tomography, while useful for imaging and assessing the extent of tumors, does not involve the extraction of cells for cytological examination.
