The machine most commonly used is called a linear accelerator or linac.

The treatment does not impact overall survival but locoregional control of the disease is important because cervical relapse can have a negative impact on the patients quality of life.

External beam radiation therapy for thyroid cancer. In a small number of cases it may be given. There is no established role for. A pubmed search was conducted to identify literature from the years 2000 to 2014 using the following terms.

External beam radiation therapy uses high energy rays or particles to destroy cancer cells or slow their growth. External beam radiation therapy ebr external beam radiation is sometimes given as an adjuvant treatment in addition to the primary treatment or as a curative treatment when the cancer cannot be removed by surgery or as a palliative approach to relieve symptoms and improve quality of life. Surgery is the mainstay of treatment for thyroid cancer.

The technique is similar to that outlined for differentiated thyroid cancer. It is very carefully delivered to protect the rest of your body as much as possible. A carefully focused beam of radiation is delivered from a machine outside the body.

External radiation or external beam radiation is the most common type of radiation therapy used for cancer treatment. After surgery and rai treatment if the cancer has not been completely removed or if there is a high risk of the cancer returning recurrence. Most people diagnosed with thyroid cancer do not need external beam radiation therapy but it may be recommended in particular circumstances.

The role for external beam radiotherapy ebrt as an adjuvant to surgery or as the primary therapy is established in anaplastic thyroid cancer but is controversial in differentiated thyroid cancer and uncertain in medullary thyroid cancer. A machine is used to aim high energy rays or beams from outside the body into the tumor. External beam radiation or x ray therapy uses radiation to destroy cancer cells.

External beam radiation therapy in which radiation is administered from a source outside the body such as a linear accelerator or a cobalt therapy machine is indicated when complete surgical excision of the tumor is not possible due to invasion of adjacent structures. Other studies have shown similar results. This type of radiation therapy is most often used to treat medullary thyroid cancer and anaplastic thyroid cancer.

External beam radiation therapy comes from a machine that aims radiation at your cancerit is a local treatment which means it treats a specific part of your bodyfor example if you have cancer in your lung you will have radiation only to your chest not to your whole body.
