2. Disadvantages of cytology:
1. The ratio of false negatives and false positives is high.
2. It is mainly used for the qualitative determination of tumor lesions (good and evil), while it is generally difficult to further determine tumor types, subtypes, invasion and metastasis. Therefore, it is only a preliminary qualitative diagnosis.
Therefore, for patients with positive cytology (malignant), biopsies should be done as far as possible to confirm the cytological diagnosis, and classification and typing before doing more damaging treatment. For those with negative cytology, it is highly suspected to be malignant tumor in clinic, or do several more cytology tests or other tests such as biopsy to prevent missed diagnosis.
