Thyroid cancer that recurs can be treated. Your doctor may recommend periodic blood tests or thyroid scans to check for signs of a thyroid cancer recurrence. Prevention. Doctors aren't sure what causes most cases of thyroid cancer, so there's no way to prevent thyroid cancer in people who have an average risk of the disease.


Importance There is wide variation in the management of thyroid nodules identified on ultrasound imaging.. Objective To quantify the risk of thyroid cancer associated with thyroid nodules based on ultrasound imaging characteristics.. Methods Retrospective case-control study of patients who underwent thyroid ultrasound imaging from January 1, 2000, through March 30, 2005.


INTRODUCTION. Ultrasound has replaced nuclear medicine as the most frequently used imaging test of the thyroid. 1 The growth in the use of thyroid ultrasound by radiologists, endocrinologists and head and neck surgeons has led to the discovery of large numbers of asymptomatic thyroid nodules, which may occur in 50% or more of adults. 2,3 as well as a rapid rise in the diagnosis of thyroid cancer.


Keep in mind, however, that an ultrasound alone cannot make the diagnosis of cancer. This test will usually help determine that the nodule has a low chance of being cancerous (has characteristics of a benign nodule), or that it has some characteristics of a cancerous nodule, and therefore a biopsy is indicated.


On average, 1 case of thyroid cancer was found for every 111 ultrasound exams performed. Thyroid nodules were found in 97% of patients with thyroid cancer and in 56% of without thyroid cancer. Microcalcifications were found in 38% of cancerous nodules and only in 5% of benign, non-cancerous nodules.


Thyroid cancer is a type of cancer that starts in the thyroid gland. Cancer starts when cells begin to grow out of control. (To learn more about how cancers start and spread, see What Is Cancer?. The thyroid gland makes hormones that help regulate your metabolism, heart rate, blood pressure, and body temperature.


Ultrasound is the first-line imaging modality for assessment of thyroid nodules found on clinical examination or incidentally on another imaging modality. This article is an overview of ultrasonographic features of thyroid nodules, which are used to determine the need for biopsy with fine needle aspiration.Specific management guidelines from various professional societies are covered in ...


After thyroid cancer is diagnosed, it is staged. Staging is a tool your doctor uses to classify characteristics about your malignant thyroid tumor. Staging the tumor helps your doctor determine the best treatment for your thyroid cancer. The staging system was developed by the American Joint Committee on Cancer (AJCC) and is called the TNM System.


Radiologists must be familiar with the various signs on ultrasound that help to distinguish benign from malignant thyroid nodules and the typical appearance of common thyroid cancer. In addition, ultrasound provides a safe tool for disease surveillance in patients with thyroid cancer after treatment.


Ultrasound imaging is a principal tool for selecting thyroid nodules for FNA biopsy in order to determine whether a nodule is benign or malignant. Choosing which nodules are worthy of biopsy based on ultrasound characteristics is especially important, and there is a vast literature on this topic. The purpose of this study was to identify the ultrasound imaging characteristics associated with ...
