A. Needle aspiration technique
Read Explanation:
Fine Needle Aspiration Cytology (FNAC)
- Definition: FNAC stands for Fine Needle Aspiration Cytology. It is a diagnostic procedure used to investigate lumps or masses in the body.
- Procedure: A thin, hollow needle is inserted into the mass or lump to extract a sample of cells or fluid. This sample is then examined under a microscope.
- Clinical Application: It is primarily used to differentiate between benign and malignant lesions. Common sites for FNAC include the thyroid gland, breast, lymph nodes, and salivary glands.
- Advantages:
- It is a minimally invasive technique.
- It is cost-effective compared to surgical biopsies.
- Results can be obtained relatively quickly (often within hours or a few days).
- It carries a lower risk of infection and bleeding compared to core needle biopsy or open surgical biopsy.
- Limitations: Because it only samples a small number of cells, it may sometimes yield an inadequate or non-representative sample, potentially leading to false-negative results if the tumor is heterogeneous.
- Preparation: Generally, no specialized preparation is required for the patient; however, anticoagulants may need to be discontinued temporarily depending on the site of aspiration.
