Interpreting FNA results requires expertise in cytopathology. The results can be categorized into several types: benign, malignant, suspicious, or non-diagnostic. Benign results indicate non-cancerous conditions, while malignant results suggest the presence of cancer. Suspicious results require further investigation, often through additional biopsies or imaging studies. Non-diagnostic results occur when the sample is insufficient or inadequate for a definitive diagnosis, necessitating a repeat FNA or alternative diagnostic methods.
