Is thyroid cancer hereditary? What are the types of thyroid cancer?

Thyroid cancer can be divided into papillary carcinoma, follicular carcinoma, and medullary carcinoma. Papillary carcinoma and follicular carcinoma are not hereditary, while medullary carcinoma is related to hereditary factors and has a hereditary tendency.

1. Papillary carcinoma and follicular carcinoma

Papillary carcinoma and follicular carcinoma are common types of thyroid cancer, which are highly malignant and develop rapidly. If not treated in time at the early stage, they may metastasize to the cervical lymph nodes or blood. This type of thyroid cancer is mainly related to acquired factors and does not have a hereditary tendency. Some people have a high incidence of familial clustering, which is mainly related to family diet, not caused by hereditary factors.

2. Medullary carcinoma

Medullary carcinoma is a type of anaplastic thyroid cancer with a poor prognosis. The main cause of the disease is due to proto-oncogene mutation. Gene mutation is a common hereditary cause of hereditary diseases. Therefore, medullary carcinoma has a hereditary tendency. If it occurs in a familial cluster, it is often related to hereditary factors.
