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.
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 ...
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 ().
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 ...
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.

According to the Cleveland Clinic, papillary thyroid cancer generally spreads slowly and more than 90% of adults go on to live at least 10 to 20 years post-treatment. Treatment
Squamous cell tumor examples that include extensive squamous metaplasia in PTC after fine needle aspiration biopsy (FNAB) (a), squamous cell carcinoma in the thyroid of putative secondary origin (b), and squamous cell carcinoma of the esophagus metastatic in the thyroid and diagnosed by FNAB (c).
Later symptoms that can be present are pain in the anterior region of the neck and changes in voice due to an involvement of the recurrent laryngeal nerve. [16] Thyroid cancer is usually found in a euthyroid patient, but symptoms of hyperthyroidism or hypothyroidism may be associated with a large or metastatic, well-differentiated tumor.
