Among all tumor forms, thyroid cancer is probably one of the rarest. In general, it can be assumed that approximately one in 30,000 people per year will develop thyroid cancer. In most cases, the affected persons are middle-aged women.
The causes for the development of thyroid tumors are still largely unclear. Over a long period of time it was assumed that a pronounced iodine deficiency in particular plays a decisive role in the development of thyroid cancer. However, this assumption has since been disproved.
Although thyroid cancers are comparatively rare, this disease can be particularly malicious. The reason for this is the fact that in the various types of thyroid cancer, recognizable symptoms only appear at an advanced stage. For this reason, the typical types of thyroid cancer are usually diagnosed by chance during a routine examination.
Irrespective of the type of tumor, symptoms only appear when the cancer cells spread to the surrounding tissue. Typical thyroid cancer symptoms include persistent hoarseness caused by paralysis of the vocal cords, difficulty breathing and difficulty swallowing. In addition, patients who have one of the four types of thyroid cancer are often diagnosed with the so-called Horner syndrome.
This syndrome is usually caused by damage to the smallest nerve tracts. Affected persons show a distinct narrowing of the pupil of one eye (miosis). In addition, the affected eyeball clearly enters the eye socket (enopthalmos) and the upper eyelid begins to hang down flaccidly (ptosis).

Depending on the cell type from which thyroid cancer develops, four types must be distinguished. The four types of thyroid cancer differ mainly in terms of the most appropriate treatment. The prognosis for thyroid cancer also depends largely on the type of tumor.
