Thyroid cancer - diagnosis should be timely
Thyroid cancer (TC) is not easy to identify in the early stages, since the feature of this type of cancer is that it often develops in the presence of other diseases of the thyroid gland and at first almost does not manifest itself. However, to identify the early stages of thyroid cancer can be: modern equipment allows it.
Basic principles of diagnosis of thyroid cancer
Diagnosis of thyroid cancer most often occurs during the medical examination and ultrasound examination of the body, so today thyroid ultrasound
Thyroid ultrasound - to examine the evidence
It is the main diagnostic method to detect cancer.
Another no less informative method is a biopsy followed by cytology content. That laboratory cytology to determine how dangerous the tumor, since prognosis depends on how differentiated (ie, have some kind of specialization, for example, similar to the tissue from which they are formed) of its cells.
If necessary for diagnosis and tumor spread are held and other diagnostic tests - computed tomography (CT), magnetic resonance imaging (MRI), positron bemissionnaya tomography (PET), X-ray and radioisotope scintigraphy of the thyroid gland.
Can detect thyroid cancer doctor during the examination
Absolutely on the basis of examination of the patient diagnosed with thyroid cancer put, of course, is not possible, it must be awakened to confirm with additional research methods.
However, an experienced doctor after the questioning and examination of the patient may be suspected thyroid cancer. In this case, the patient is directed primarily to the US.
Thyroid ultrasound
Ultrasonography allows to investigate the thyroid gland without damaging it (ie, a non-invasive method of diagnosis) and not irradiated. This reveals the tumor sizes up to 1 to 2 cm, its dimensions are determined by the contours of the structure, the presence or absence of various inclusions, such as calcifications. Using ultrasonic Doppler blood flow is investigated in an area where a tumor develops, and thyroid gland in general.
If during the ultrasound examination there was a suspicion of thyroid cancer, must be conducted ultrasound cervical lymph nodes with needle biopsy and subsequent laboratory research content.
CT, MRI and PET
Computed tomography (CT) does not allow to detect small nodules in the thyroid gland, but that using this method can detect tumor metastasis, located behind the trachea, sternum and along the cluster of nerves and blood vessels.
Magnetic resonance imaging (MRI) is a very informative and reveals little education in thyroid tissue, and see education, located behind the trachea and bronchi, that is the extent of the process, including the metastasis
Metastasis - danger everywhere
in the lymph nodes.
6emissionnaya Positron tomography (PET) revealed data on metabolism
Metabolism: The basis of life of all living things
in cells and tissues of the changes that occur in these cells. At present technique is not fully understood.
X-ray diagnostic techniques
This method of research, and today is not outdated. So review chest X-ray can detect not only thyroid cancer, but its metastases in the lymph nodes and lungs. Radiographs of other organs allow us to see distant metastasis of the tumor. A sighting tomography (stratified study of tissue) allows you to see exactly where the tumor is located, especially its structure and contours, the displacement of surrounding soft tissues.
Laboratory methods of diagnostics
If you suspect a TC held needle aspiration biopsy (FNA), followed by the study of cellular material taken in cytology laboratories. FNA is conducted in all patients who were identified nodal changes in the thyroid gland
The thyroid gland - is responsible for your hormones
. In some cases, FNA is performed under ultrasound guidance - it increases the diagnostic value of the study. In the subsequent cytological examination revealed the tumor cells of the tumor, set the degree of differentiation (the less differentiated cells of the tumor, the worse the prognosis) and cellular origin.
Molekulyarno6geneticheskie methods today are considered the most informative, but it is rarely used because of the high cost.
After being diagnosed with thyroid cancer set, an occasion surgery, during which the removal of the tumor tissue is studied in the laboratory at the time. as the patient is on the operating table.
Timely detection of thyroid cancer makes it possible to save the patient.
