In line with giving more humanistic care to patients and their families and the advancement of modern medicine, needle biopsy is playing an increasingly important role in the diagnosis of breast tumors. Needle biopsy includes: fine needle aspiration (FNAC), core needle aspiration (CNB), and vacuum assist (VAB).
Fine needle aspiration cytology (FNAC)
A kind of cytodiagnostics that uses a fine needle (thin needle with an outer diameter <0.9mm) to puncture and draw cells and other components in the lesion to make a smear to observe the morphological changes and interstitial changes of tumor and non-tumor cells.
During the implementation, according to the texture and properties of the tumor, a disposable syringe with a size of about 10 cm can be used for puncture. Through the patient's body surface, suck out the palpable mass lesions, or perform needle aspiration on the lesions of deep organs with auxiliary guidance such as X-ray, B-ultrasound, CT and MRI scan, and suck out tiny tissue components (including cells, interstitial or other Concomitant) for cytomorphological diagnosis.
