There are four main types of cancers that occur in the thyroid gland. The type of cancer is the most important factor affecting prognosis. The two most common types, papillary and follicular, if treated appropriately, have excellent prognoses, depending on the stage of the cancer when first detected. The remaining two types of thyroid cancers, medullary and anagplastic are more likely to result in poorer outcomes.
These factors increase your risk of developing thyroid cancer. Tell your doctor if you have any of these risk factors:
If you have any of these symptoms do not assume it is due to thyroid cancer. These symptoms may be caused by other conditions. Tell your doctor if you have any of these symptoms:
The doctor will ask about your symptoms and medical history, and perform a physical exam. This may include a careful examination of your neck to look for lumps or abnormalities.
Once thyroid cancer is found, staging tests (possibly including CT/MRI scans and PET scans) are done to find out if the cancer has spread. Treatment depends on the stage of the cancer.
Thyroid surgery may include removal of one lobe for biopsy to determine if a nodule within the thyroid lobe is cancerous. The specimen (thyroid lobe) may be examined by a pathologist while you are still under the general anesthetic. While not 100 percent accurate, the pathologist may return with a diagnosis of cancer. At that point the surgeon may remove the opposite lobe of the thyroid gland, this is called a total thyroidectomy.
This uses large doses of radioactive iodine to destroy any remaining thyroid tissue and thyroid cancer without affecting the rest of the body. This treatment is used to destroy thyroid tissue not removed by surgery and to treat thyroid cancer that has spread to lymph nodes and other parts of the body.
This is the use of radiation to kill cancer cells and shrink tumors. Radiation is directed at the tumor from a source outside the body. It is rarely used for thyroid cancer.
This is the use of drugs to kill cancer cells. Chemotherapy may be given in many forms including: pill, injection, or through a catheter. The drugs enter the bloodstream and travel through the body killing mostly cancer cells, but also some healthy cells. Chemotherapy to treat thyroid cancer is still investigational. Chemotherapy has not been shown to effectively control or kill thyroid cancer.
Because the exact cause of thyroid cancer is unknown, finding it early and treating it is the best way to prevent dying from the disease:
Exposure to radiation is a major risk factor for thyroid cancer, therefore:
