What are the classifications of thyroid cancer? Thyroid cancer is generally divided into these 5 types

One of the types of thyroid cancer is papillary thyroid cancer, which is the most common type of thyroid cancer. Although the incidence is high, the prognosis is relatively good, with a 10-year survival rate of up to 90%. Follicular thyroid cancer and medullary thyroid cancer are also common types of thyroid cancer. In addition, thyroid cancer also includes thyroid lymphoma and anaplastic cancer.

The thyroid gland is mainly responsible for secreting thyroid hormones and is one of the most important endocrine organs. If you do not pay attention to protecting it, you may suffer from various thyroid diseases, such as thyroid cancer. Thyroid cancer is a very serious thyroid disease, which is divided into many different types. Let's take a look at the classifications of thyroid cancer.

1. Papillary thyroid carcinoma

Papillary thyroid carcinoma is one of the more common types of thyroid cancer, accounting for about 50% to 70% of thyroid cancers. The prognosis of papillary thyroid carcinoma is relatively good, with a 10-year survival rate of up to 90%. However, this type of thyroid cancer is prone to lymph node metastasis, with a metastasis rate of 40% to 50%. However, the hazard of lymph node metastasis is not particularly great. As long as the treatment is timely and standardized, it will not have an adverse effect on the prognosis, but the chance of local recurrence will increase.

2. Follicular thyroid cancer

Thyroid cancer also includes follicular thyroid cancer, which has an incidence of about 5% to 20%, and mainly affects middle-aged and elderly women over 40 years old. Follicular thyroid cancer is prone to distant metastasis, and the main sites of metastasis are the lungs and bones. If it can be detected and treated in the early stage, the 10-year survival rate can reach 80%, but if distant metastasis occurs, the survival rate will be greatly reduced.

3. Medullary thyroid cancer

Medullary thyroid cancer is also a common type of thyroid cancer, with an incidence of about 3% and a poor prognosis. Once you have medullary thyroid cancer, you need to have the entire thyroid removed surgically in a timely manner without leaving any thyroid tissue.

4. Thyroid lymphoma

The incidence of this type of thyroid cancer is about 2%, and the main patients are women aged 50 to 60. The 5-year survival rate of the disease is about 75%. This disease is usually preceded by thyroiditis, and sometimes coexists with Hashimoto's thyroiditis.

5. Anaplastic thyroid cancer

Anaplastic carcinoma is a type of thyroid cancer with a relatively low incidence rate. It usually occurs in older people. The main manifestations of this type of thyroid cancer are difficulty swallowing and breathing, accompanied by obvious neck pain. It is difficult to detect and treat the disease in the early stages. The prognosis of this disease is particularly poor, and most people will die within 6 to 12 months after onset.
