How to Avoid Medullary Thyroid Cancer
Though there are many kinds of thyroid cancer, medullary tumor is the third most well-known of all. In distinction to papillary and follicular thyroid cancers, medullary thyroid cancer occurs from the C cells or parafollicualr cells of the thyroid. In addition, the abovementioned kinds of this cancer occur from the producing cells of thyroid hormone. These C cells create a different hormone and this is known as calcitonin.
Although this hormone has nothing to do with controlling the metabolism of a person the way the thyroid hormone does, the calcitonin may be calculated after surgery to view if there is any symptom of a cancer is still developing or growing. Medullary thyroid cancer has a low rate for treatment when compared to follicular and papillary cancers. When the whole illness is verified to have not been spread around the thyroid gland, a one decade rate of survival can be anticipated with up to 90 percent assurance.
On the other hand, if the illness has transmitted to cervical lymph nodes, then a one decade of survival rate can be anticipated with up to 70 percent. It turns into a 20 per cent of assurance if this condition has been diagnosed in isolated parts. This form of cancer is much common in women than in men. This can also be related with other endocrine tumors. When it spreads to neck lymph nodes, it occurs in the early phase of the condition.
Aside from that, it is also late to transmit to distant parts like adrenal medulla, brain, liver and bone. This form of cancer is not related with the exposure in any kind of radiation. This is usually begins in the upper-middle lobe of the thyroid gland. Even if the tumors are successfully removed through surgery, there can be some residual traces left or it occurs again. Furthermore, the growth pattern of this type of thyroid cancer is sluggish, but progressive.
The local attack of nearby structures is also common. The cancerous development transmits hematogenously with metastases and the clinical series of this form of cancer is changeable. Although there may be early metastases to mediastinal and cervical lymph nodes in as many as 70 percent of patients, the tumor is still normally performs in an apathetic way. That is why it is recommendable that once you experience some of its symptoms, you need to see and consult your doctor immediately.
