Can thyroid cancer be mistaken?
Fine-needle aspiration (FNA) is commonly used as a preoperative assessment to diagnose thyroid cancer. However, misdiagnosis of malignancy by FNA is not rare, even if image examination suggests the possibility of thyroid cancer.
Can you be misdiagnosed with thyroid cancer?

How often are highly suspicious thyroid nodules cancerous?
Conclusion: The rate of malignancy found here for nodules with highly suspicious sonographic features, even after two FNA showing benign cytology, was 2%. We believe that in these cases, the continuation of follow-up consisting of ultrasound at intervals of 2 years may still be adequate.
What is the average size of a cancerous thyroid nodule?
When the analysis of nodule size was compared with the type and distribution of thyroid malignancy, a significant relationship was detected. The majority of cancer cases, having a nodular size of 1.0-1.9 cm, were diagnosed as papillary carcinoma, and 61.9% of cancerous nodules ≥4 cm were follicular carcinomas.
How can you tell if a thyroid nodule is malignant?
Biopsy. The actual diagnosis of thyroid cancer is made with a biopsy, in which cells from the suspicious area are removed and looked at in the lab.

What does it mean when a thyroid biopsy comes back suspicious?
“Suspicious” thyroid biopsy: this happens usually when the diagnosis is a follicular or hurtle cell caused lesion. Follicular and hurtle cells are normal cells found in the thyroid. Current analysis of thyroid biopsy results cannot differentiate between follicular or hurtle cell cancer from noncancerous adenomas.
What are the characteristics of a cancerous thyroid nodule?
Ultrasound can detect the presence, site, size, and number of thyroid nodules, and there have been reports of US characteristics of malignancy, such as ill-defined margin, irregular shape, hypoechogenicity, heterogeneity, absence of cystic lesion and/or the halo sign, the presence of calcification, and invasion to …
