What is the main benefit of using fine needle aspiration in oncology diagnostics?

The primary advantage of utilizing fine needle aspiration (FNA) in oncology diagnostics lies in its non-invasive and quick nature. This technique allows for the collection of cells from a mass or lesion using a thin, hollow needle. Because it doesn't require large incisions or extensive surgical procedures, it minimizes trauma to the patient and allows for faster sampling, resulting in quicker results for diagnosis.

Fine needle aspiration is particularly valuable in veterinary oncology because it can be performed with minimal risk to the animal and often does not necessitate anesthesia or sedation, making it a practical option in a clinical setting. The speed and simplicity of the procedure enable rapid decision-making regarding diagnosis and treatment, which is especially critical in oncology where time can impact the course of disease and management options.

While FNA can provide valuable diagnostic information, it may not always yield a definitive diagnosis, as it primarily provides cytological information. Therefore, this method is often part of a broader diagnostic workup that may include additional imaging or biopsy techniques if further information is required.
