Most patients suffering from thyroid cancer undergo surgery as part of the treatment. The doctors remove a part of the thyroid or all of it, depending on the stage of the disease when it was discovered and also on the severity of the illness. Because the thyroid is only a small organ situated in the throat area of a person, the surgery is minimally invasive and the scar will be very small.When the surgery removes the whole thyroid it is called total thyroidectomy and it can also remove the lymph nodes around the thyroid during the same surgical procedure, if the doctor finds any cancer cells in these lymph nodes.

Sometimes the patients undergoing this surgery will have to follow radioactive iodine treatment and external radiation therapy, too, in order to provide the best results possible. The thyroid is shaped like a butterfly, with two lobes on the sides and when only one lobe is affected the patient will have a lobectomy, that is only the sick lobe will be removed.
If the surgery removed all the sick tissue, the patient will recover successfully and lead an almost normal life in the future. The only problem might be if the thyroid is completely removed, because in this case the patient will have to take a pill every day because we can't live and be healthy without the hormone that is produced by thyroid, so you will have to replace it with medication. But I don't see it as a major inconvenient.
Besides surgery there are three more standard types of treatment used in thyroid cancer. The next one is radiation therapy, which includes radioactive iodine therapy. It uses x-rays or another type of radiation to kill the cancer cells and also to prevent them from growing and spreading. There is the external radiation therapy which uses a machine to direct radiation towards the sick tissue and internal radiation therapy that uses a radioactive liquid substance that the doctors introduce directly in the tumour with the help of needles and seringes. This type of treatment is often used in addition to surgery to remove any sick cancer clls that might have remained after surgery. This is a very effective and accurate method as the radioactive iodine used only affects the thyroid cells and distrys them , leaving the tissue around unharmed.

The third type of treatment is called chemotherapy because it uses chemicals - drugs - for killing the sick cells or stopping them from growing and spreading around the body. It can be local , applied directly to the sick organ or injected in the blood stream or taken as pills that end up in the stomach and again in the blood stream that takes the active substance in the whole body. Only the doctors that take care of each case can decide what kind of chemotherapy to use and also the qualntity of drug that is necessary, according to the patients response and the stage of the disease.
The last type of thyroid cancer treatment is thyroid hormone therapy that I mentioned above and which supplies the human body with the necessary quantity of thyrois hormone.
But researches are made as we speak about all kinds of cancer and the ways they must be treated best, so there may be some other methods that will be used soon.
