Thyroid cancer can find out, certain answers regarding risk factors and basic health diagnoses. TSH testing lab, a physical examination, fine-needle aspiration (FNA) and diagnostic imaging are also required to be performed.

A physical examination includes inspection of the thyroid) for probable swelling, for tenderness, pain, and expansion of all types in the nearby lymph nodes and also for the investigation of the node for texture,Size and consistency. The node will be benign, if the node is smooth, mobile and soft. However, if it is irregular, stiff, strong and rigid, because the possibility is that the node is malignant.

Thyroid-stimulating hormone (TSH) blood test must be conducted in order to accommodate the function of the thyroid. This test verifies availability and the nature of the thyroid, ie, either hypo-thyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).

Ultrasonic and radionuclide scanning (commonly thyroid scan ") are typically used for diagnostic imaging of the gland itself. The number of nodes and the character of the nodes, the cystic or solid, by ultrasound or ultrasound can be determined. But although malignancy could not be ascertained, it is a good indicator of the fluctuations in the size (an increase or decrease) of the node. The> Thyroid composition, function and position are using the information reported by the scan.

Substances with radioisotopes it orally or by injection for thyroid scans. The thyroid tissue absorbs this substance, which can make a small dose of technetium containing specially prepared, or radioiodine. Thyroid carcinomas are divided into two groups, it was "hot" or "cold" . The capacity for the radioiodine uptake will decide in whichCategory, a thyroid node falls.

If the node contains radioactive iodine, which is more than or even equal to the adjacent thyroid tissue, a hot node. Sometimes scan, the remaining thyroid gland becomes invisible due to the excessive thyroid hormone creation of the hot nodes. The level of production is so great that the remaining thyroid gland'sFeatures are hidden. This kind of node is not malicious.

A cold knot is that in the radioiodine absorbed or not at all included, even if the content is very low. It is noticed that most of the time benign cysts and tumors cold, although cancer examined, are also cold. The existence of a cold nodule was regarded as a warning for additional evaluation, even though statistics show only 10 percent (approximately) from this type of individualNodes are malignant.

If a distinction between malignant and benign nodes will be the most efficient way is to puncture method or FNA. Through this method, a thyroid tissue for microscopic examination of the first anesthesia of the skin over the area of the node, and then get out a small needle into the nodule for about 10-60 seconds.
