What is the prognosis with thyroid cancer? Some types of this cancer have a high survival rate, while others have a lower rate due to the aggressiveness of the cancer.
Papillary Thyroid Cancer
Papillary thyroid cancer is the most common type of thyroid cancer, and also has a good prognosis. MedlinePlus noted that more than 95 percent of adult patients survive at least 10 years post-diagnosis.
Prognosis is dependent on certain factors. For example, patients who have small thyroid gland tumors or who are younger than age 40 have a better prognosis.
People who have a large tumor or are older than age 45, however, have a worse prognosis. Other factors that affect the prognosis with papillary thyroid cancer include cancer that spread to the soft tissue or to distant parts of the patient’s body.
Follicular Thyroid Cancer
While follicular thyroid cancer is a fast-growing type of thyroid cancer, it can have a good prognosis. The survival rate for follicular thyroid cancer depends on the pathology of the tumor. Unfortunately, surgery is the best way to obtain a sufficient sample to be examined.
Tumors with venous capsular invasion or microscopic capsular invasion can have a cure rate of 99 percent while other tumors may only have a 40 percent, 10-year survival rate, according to Columbia University Medical Center.
Medullary Thyroid Cancer
The prognosis for medullary thyroid cancer can vary. Patients with familial medullary thyroid cancer have the best prognosis, while patients with MEN 2B associated medullary thyroid cancer have the worst.
Columbia University Medical Center noted that when the cancer is found early and has not spread beyond the thyroid gland, the 10-year survival rate is 80 percent. But when the cancer spreads to the lymph nodes or other areas of the body, such as the liver, the rate decreases to 25 percent. MedlinePlus added that women who are younger than 40 years older have a better prognosis.
Anaplastic Thyroid Cancer
Of all the types of thyroid cancer, anaplastic thyroid cancer has the worst prognosis.
