Measurement of thyroid stimulating hormone and anti-thyroid antibodies will help decide if there is a functional thyroid disease such as Hashimoto's thyroiditis present, a known cause of a benign nodular goitre. [4] Fine needle biopsy for cytopathology is also used. [5] [6] [7] Thyroid nodules are extremely common in young adults and children.
The accuracy of the diagnosis depends on obtaining tissue from all of the suspicious areas of an abnormal thyroid gland. The reliability of fine needle aspiration is increased when sampling can be guided by ultrasound, and over the last 15 years, this has become the preferred method for thyroid biopsy in North America.

Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]
New diagnoses of thyroid cancer in the U.S. are triple what they were 50 years ago, and recent literature links this to both the increased use of diagnostic imaging and fine-needle aspiration ...
Papillary thyroid carcinoma is usually discovered on routine examination as an asymptomatic thyroid nodule that appears as a neck mass. In some instances, the mass may have produced local symptoms. This mass is normally referred to a fine needle aspiration biopsy (FNA) for investigation. FNA accuracy is very high and it is a process widely used ...
Thyroid cancer affects tens of thousands of people per year, and the majority are women. Of the 44,000 people who will likely be diagnosed with thyroid cancer this year, more than 31,000 will be ...
The Bethesda System for Reporting Thyroid Cytopathology is the system used to report whether the thyroid cytological specimen is benign or malignant on fine-needle aspiration cytology (FNAC). It can be divided into six categories:
Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses.In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained, are examined under a microscope ().
