Types of Thyroid cancer and its symptoms

What is Thyroid Cancer?

Thyroid cancer actually refers to the four kinds of malignant tumors that take place in the thyroid gland. The four malignant tumors are the papillary, follicular, medullary and anaplastic type. Among these the papillary and follicular tumors are more common. These tumors normally grow slow and are found that these diseases are fatal only for those who are above the age of 45 years. Medullary tumors are prognosis friendly when they are found restricted to the thyroid glands and becomes poor when metastasis occurs. Anaplastic tumors are fast growing compared with the other tumors and their response towards the therapy is poor.

Symptoms of thyroid cancer:

The foremost symptom of the thyroid cancer is the projection of the nodule in the neck region. We find many adults who have nodules in the neck region. Sometimes the first symptom may be a lymph node that is enlarged. The symptoms are then followed by the pain in the anterior region and voice
changes. A euthyroid patient usually fall victim to the thyroid cancer but the hyper thyroid symptom can be associated with the metastatic tumor. Nodules are separate concern when they are found in members under
the age of twenty years.

Various types of Thyroid cancer:

According to the pathological characteristics the thyroid cancer can be classified into four types. They are the following.

  • Papillary thyroid cancer
  • Follicular thyroid cancer
  • Medullary thyroid cancer
  • Anaplastic thyroid cancer

The other classifications rather than these are the lymphoma and the squamous cell carcinoma. Among the above classifications the follicular and the papillary types are the differentiated cancer types.
