What happens if FNAC is positive?

What happens if the FNAC test is positive? A positive FNAC test does not necessarily indicate cancer. Your doctor may recommend additional tests to establish a final diagnosis based on your medical history, complaint, signs and symptoms, and clinical examination.

Why FNAC of thyroid is done?

Doctors use fine-needle aspiration biopsy of the thyroid to treat thyroid cysts or detect cancer in a thyroid nodule. Fine-needle aspiration biopsy (FNAB) of the thyroid is a procedure used to detect cancer in a thyroid nodule or to treat thyroid cysts.

Can FNAC test detect thyroid cancer?

More specifically, some studies aimed to determine FNAC accuracy in diagnosis of thyroid cancer; however, it should be noted that FNAC cannot differentiate between benign and malignant follicular neoplasms.

Why FNAC test is required?

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. This procedure is also used to test for thyroid, salivary glands and lymph nodes illnesses.

What if thyroid biopsy is positive?

A positive marker indicates the need for a total thyroidectomy instead of a lobectomy, and negative markers may support a decision to forgo surgery for a follicular lesion of undetermined significance. Further studies are needed to determine the utility of these tests for indeterminate nodules.

What if FNAC test is negative?

When FNAC shows a positive finding, treatment should be given accordingly as FNAC has a high PPV. However, when FNAC shows a negative result, malignancy cannot be reliably ruled out since the NPV of FNAC is low (37%). PET/CT is then performed in these patients.

Which is better FNAC or biopsy?

Core biopsy is better than FNAC at preoperative diagnosis of screen-detected breast cancer as it missed fewer cancers. However, combining FNAC resulted in a better preoperative diagnosis rate.

Is biopsy and FNAC 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.

• swollen glands in the neck.
• unexplained hoarseness that does not get better after a few weeks.
• a sore throat that does not get better.
• difficulty swallowing.

Can FNAC be false negative?

False negativity of FNAC does occur; this could be caused by either “true” false-negative cases attributed to suboptimal sampling technique, poor localization of the mass or nonpalpable lesions or “false” false-negative cases due to interpretational errors.

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].

How much does FNAC test cost?

The average cost of the FNAC Test in India is usually between Rs. 1000 to Rs. 6000. However, the prices may vary depending upon the hospitals in different cities, the type of tests, and disease location.

How painful is FNAC test?

FNAC is generally well-tolerated procedure with most patients experiencing either mild pain or no pain during the procedure. No patients experienced severe pain. There was no difference in VAS scores between lymph node biopsy and salivary gland biopsy.

What is FNAC test for neck?

Abstract. 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.
