FINE NEEDLE ASPIRATION CYTOLOGY (FNAC)

FINE NEEDLE ASPIRATION CYTOLOGY (FNAC)

Fine needle aspiration cytology (FNAC) is a diagnostic procedure in which a thin, hollow needle is inserted into a mass or lump, such as a cyst, to obtain a sample of cells for examination under a microscope. The procedure is performed under local anesthesia and is relatively quick, simple, and safe.

The needle used for FNAC is thin and hollow, and it is inserted into the mass or lump. The cells are then suctioned out of the mass or lump and collected on a microscope slide. The slide is then sent to a laboratory for examination. The procedure is usually performed by a Cytopathologist or a Pathologist.

FNAC is commonly used to diagnose and monitor a wide range of conditions, including but not limited to: thyroid nodules, breast lumps, lymph nodes, and liver cysts. The procedure can also be used to diagnose cancer, infection, or inflammation. It is especially useful when a mass is not accessible for a biopsy or when a patient is not able to undergo a surgical procedure.

The procedure has high accuracy for diagnosis of benign and malignant tumors, however, it is not able to provide information about the stage of the cancer. It is used as a tool to provide a diagnosis, and if malignancy is suspected, a biopsy is recommended to confirm the diagnosis and to provide more information about the stage of the cancer.

In summary, Fine needle aspiration cytology (FNAC) is a diagnostic procedure in which a thin, hollow needle is inserted into a mass or lump to obtain a sample of cells for examination under a microscope. It is commonly used to diagnose and monitor a wide range of conditions and is a useful tool to provide a preliminary diagnosis, however, a biopsy is recommended to confirm the diagnosis and to provide more information about the stage of the cancer.

Fine needle aspiration cytology (FNAC) is a simple, safe, and cost-effective procedure that can be performed in a doctor's office or clinic. The procedure is usually well tolerated by patients, and complications are rare. Some patients may experience slight discomfort or pain during the procedure, but this is usually minimal.

The sample obtained by FNAC is examined under a microscope by a cytopathologist or pathologist, who will look for abnormal cells or signs of infection or inflammation. The results of the FNAC can be available within a few days, depending on the lab's workload and the complexity of the sample.

FNAC has a high sensitivity and specificity for the diagnosis of malignancy, and it is considered to be a reliable and accurate method for the diagnosis of many types of cancer, including thyroid cancer, breast cancer, and lymphoma. However, in some cases, the sample obtained by FNAC may not be sufficient to make a definitive diagnosis, and a biopsy may be necessary.

It is important to note that FNAC is not recommended for the diagnosis of certain types of cancer, such as sarcomas, or for the diagnosis of certain types of benign conditions, such as inflammatory conditions. In these cases, a biopsy is usually necessary to make a definitive diagnosis.

In summary, Fine needle aspiration cytology (FNAC) is a simple, safe, and cost-effective procedure that can be used to obtain a sample of cells from a mass or lump for examination under a microscope. The procedure has high sensitivity and specificity for the diagnosis of malignancy, but it may not be sufficient to make a definitive diagnosis in some cases, and a biopsy may be necessary.
