Can a benign thyroid tumor become malignant?
Conclusion: Some benign thyroid nodules have malignant potential. Further molecular testing of these tumors can shed light on the pathogenesis of early malignant transformation.
Can thyroid nodules grow and not be cancerous?
Colloid nodules: These are one or more overgrowths of normal thyroid tissue. These growths are benign (not cancer). They may grow large, but they do not spread beyond the thyroid gland.
How do I know if my thyroid nodule is benign?
If the follicular cells are contained within the nodule, the condition is called benign. If the cells have invaded the surrounding tissue, the diagnosis is cancer. Thyroid cysts are nodules filled with fluid. If a nodule has both fluid and solid parts, it is called a complex nodule.

Can an ultrasound tell if a thyroid nodule is cancerous?
An ultrasound may show your doctor if a lump is filled with fluid or if it’s solid. A solid one is more likely to have cancerous cells, but you’ll still need more tests to find out. The ultrasound will also show the size and number of nodules on your thyroid.
Can a highly suspicious thyroid nodule be benign?
A thyroid nodule is a discrete lesion within the thyroid gland that is radiologically distinct from the surrounding tissue. Nodules are common and found in 10 percent of the adult population. Luckily, most of them are benign.
How can you tell if a thyroid nodule is malignant?
You can not tell if a thyroid nodule is malignant due to symptoms or lack of symptoms. Those thyroid nodules that are cancer, tend to be very slow growing. The very rare thyroid nodule that is an aggressive thyroid cancer may present with a large thyroid mass, firm or non-mobile mass or even change in vocal quality.
