What Happens If FNAC Test Is Positive?


A Mantoux test was also done in these patients. A Mantoux test was further done in patients of reactive lymphadenopathy where the lymph node size was more than 1 cm. If the result was positive, a repeat FNAC was performed. When the repeat FNAC showed ill-defined granulomas, excision biopsy was done.

Can FNAC test detect cancer?

Fine needle aspiration is most sensitive at detecting anaplastic (almost 100%) and papillary (around 90%) carcinomas. Although FNAC has greater accuracy in identifying tumours than alternative imaging or biochemical methods, it misses 5-10% of cancers.

Does FNAC mean cancer?

Fine Needle Aspiration Cytology, a new and easy cancer diagnostic procedure. When a lump, or a bump is discovered in superficial areas of the body such as the breast and neck, a test known as Fine Needle Aspiration Cytology (FNAC) is recommended to determine whether the lump is cancer.

Is FNAC and biopsy same?

The sampling and biopsy considered together are called fine-needle aspiration biopsy (FNAB) or fine-needle aspiration cytology (FNAC) (the latter to emphasize that any aspiration biopsy involves cytopathology, not histopathology). Fine-needle aspiration biopsies are very safe minor surgical procedures.

Can FNAC go wrong?

Nevertheless, like any other test, FNAC has its limitations and diagnostic pitfalls. These limitations include false negative and false positive results and a proportion of FNA results that are not obviously benign or malignant and fall into the indeterminate or suspicious group [5].

What is the result of FNAC test?

Results. FNAC had a specificity of 99.6%; sensitivity, 97.4%; positive predictive value, 99.6%; negative predictive value, 97.6%; and accuracy, 98.5%.

Which is better FNAC or biopsy?

The sensitivity of core biopsy was 96%, specificity was 100%, the predictive value of a positive result was 100%, and the diagnostic efficiency was 98%. There was no significant difference in the diagnostic value (sensitivity, specificity and accuracy) of CNB and FNAC with a p value of more than 0.05(Table-5).


What is FNAC test cost?

Ans – The average cost of the FNAC test varies from Rs. 1400 to Rs. 2000.

How does cancer start?

Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumors.

What is FNAC done for?

Background: Fine Needle Aspiration Cytology (FNAC) is a simple, quick and inexpensive method that is used to sample superficial masses like those found in the neck and is usually performed in the outpatient clinic. It causes minimal trauma to the patient and carries virtually no risk of complications.

How long is FNAC report?

Generally, your results should be available from your surgeon’s office in two to three working days. The results can be grouped into three categories: Clearly benign – not cancer. Clearly malignant – cancer.

Is FNAC conclusive?

Conclusion. The overall diagnostic accuracy of FNAC of cervical lymph nodes was 82.2% while the overall discordance rate was 17.8%.

Is biopsy required after FNAC?

Even if an FNA does find cancer, there might not be enough cancer cells to do some of the other lab tests that are needed. If the results of the FNA biopsy do not give a clear diagnosis, or your doctor still has concerns, you might need to have a second biopsy or a different type of biopsy.

Is FNA painful?

It is non-invasive and only slightly uncomfortable, compared to a surgical biopsy which requires a general anaesthetic, involves pain and the possibility of infection or scarring. Fine needle aspiration biopsies do require some expertise to perform and interpret.

Can I eat before FNAC test?

Do not eat or drink anything for several hours before the procedure. If you will be getting sedating medication, be sure to bring someone with you to drive you home.
