Goiter Thyroid

Goiter and thyroid cancer are two different conditions that affect the thyroid gland, with important differences and similarities. Both can be serious medical conditions if left untreated; understanding the differences can help guide medical decisions.

What Is a Goiter?

A goiter is an abnormally enlarged thyroid gland.

What Is Thyroid Cancer?

Thyroid cancer is a type of cancer that affects the thyroid gland. It can present in a number of ways, but is often painless at first, typically manifesting as a lump or swelling in the neck. The most common types of thyroid cancer include papillary thyroid cancer, follicular thyroid cancer, and medullary thyroid cancer.


The most obvious difference between a goiter and thyroid cancer is that a goiter is usually not cancerous. In addition, goiters can generally be managed with medical treatment, whereas thyroid cancer usually requires surgical treatment. Furthermore, goiters can often be detected through imaging tests, whereas thyroid cancer may require a biopsy for diagnosis.
