Being female increases your risk compared to males, and factors like obesity, a history of benign thyroid conditions and potential exposure to environmental pollutants are also associated with an increased risk. 

Types of Thyroid Cancer:

Papillary thyroid cancer is the most common type. These cancers tend to grow very slowly. They sometimes spread to the lymph nodes in the neck they can often be treated successfully and has good prognosis.

Follicular thyroid cancer is the next most common type; The prognosis for follicular cancer is not quite as good as that of papillary cancer, although it is still very good in most cases.

 Medullary thyroid cancer accounts for less than 5% of all thyroid cancers. It can be harder to find and treat. Sometimes it can spread to the lymph nodes, lungs, or liver before a thyroid nodule is even discovered. Most often it runs in families and is due to genetic mutation.

Anaplastic thyroid cancer is rare. It makes up about 2% of all thyroid cancers.   It is most advanced and aggressive. Generally does not respond to treatment, thus has bad prognosis
