What is the cancer detection rate of needle aspiration?

The correct choice reflects the cancer detection rate based on the understanding of needle aspiration techniques, particularly fine needle aspiration (FNA). Needle aspiration is a minimally invasive procedure commonly used to sample cells from suspicious lesions, particularly in organs such as the thyroid, breast, and lymph nodes.

The cancer detection rate for FNA typically ranges from 6% to 30%. This range considers various factors, including the type of lesion being biopsied, the experience of the clinician performing the aspiration, and the cytological evaluation process. In many cases, while FNA is a valuable diagnostic tool, its sensitivity can vary depending on the location, the nature of the mass, and the characteristics of the cells collected.

This range is widely accepted in medical literature, supporting the idea that while needle aspiration can be effective in identifying malignancies, it does not guarantee a definitive diagnosis in every case, and further evaluations may be necessary to confirm findings.

Understanding the range of cancer detection rates helps clinicians set appropriate expectations for patients and informs them about the potential need for additional diagnostic procedures.
