How thyroid cancer is diagnosed?

The actual diagnosis of thyroid cancer is made with a biopsy, in which cells are removed from the suspicious area and examined in the laboratory. If your doctor thinks a biopsy is needed, the easiest way to determine if a thyroid nodule or tumor is cancerous is by fine needle aspiration (FNA) of the thyroid nodule. Although a blood test can't diagnose thyroid cancer, it can check levels of T3, T4, and thyroid-stimulating hormone (TSH). In general, the thyroid works normally even if there is thyroid cancer, and hormone production will not be affected.

However, this blood test can rule out benign thyroid conditions, such as hypothyroidism or hyperthyroidism. Thyroid cancer is histologically diagnosed using an FNA biopsy and is classified into 4 main types. Papillary thyroid carcinoma, which accounts for approximately 70 to 80% of thyroid cancers, is the most common thyroid malignancy, 5,8 Papillary thyroid carcinoma is the least aggressive type of cancer, as it tends to grow and metastasize slowly, 5,8 It is composed of multifocal papillary and follicular elements formation of adenocarcinoma sites, 8.As an alternative to surgery or other treatments, you might consider active surveillance with frequent cancer monitoring. Radioactive iodine scintigraphy uses a radioactive form of iodine and a special camera to detect thyroid cancer cells in the body.

MRI can be used to look at the brain and spinal cord, places where thyroid cancer can spread (metastasize). The health care team uses information from your tests and procedures to determine the extent of the cancer and assign a stage to it. Even so, your doctor may want one done to help determine if the thyroid gland is working properly. Increased treatment options for patients with thyroid cancer, including therapies recently approved by the U.S.

Food and Drug Administration, have kept the mortality rate from this malignancy low, despite its increasing incidence. If you have a thyroid nodule or an enlarged lymph node in your neck, you may need a fine needle aspiration (FNA) biopsy. Radiologically, they are lesions within the thyroid gland that are distinct from the surrounding thyroid parenchyma. The landmark DECISION study, which led to FDA approval of sorafenib, was a phase 3, multicenter, randomized, double-blind, placebo-controlled clinical trial that included patients with progressive, locally relapsing, or metastatic differentiated thyroid cancer.

All of these treatment options have kept the mortality rate from thyroid cancer low, despite the recent increase in incidence. For example, an ultrasound scan can help the oncologist inspect the thyroid for nodules, and a biopsy can be taken to remove and analyze tissue samples to determine if a thyroid nodule is cancerous. If your provider suspects that you may have a thyroid problem, you may be referred to a doctor who specializes in diseases of the endocrine system (endocrinologist). The standard treatment approach for differentiated thyroid cancer involves multimodal treatment according to the management guidelines of the American Thyroid Association; however, its economic analysis showed that 55% of patients did not receive radiation therapy and 6.5% received other types of radiation therapy, indicating which had received less aggressive care that was not in line with current guidelines.
