Clipboard, Search History, and several other advanced features are temporarily unavailable. For reprint requests, please see our Content Usage Policy. Thyroid cancer also tends to be more aggressive in people who are older. With rare exception, a maximum of 2 nodules were aspirated during a single visit. If FNA results were nondiagnostic, a reaspiration was performed 1 or more times until a cytological diagnosis was successfully obtained or the patient elected surgical resection prior to a cytological diagnosis. People can develop thyroid nodules at any age, but they occur most commonly in older adults. WebWhat percentage of suspicious thyroid nodules are cancerous? Neither a thyroid scan nor radioiodine treatment should ever be given to a pregnant woman. Roughly two-thirds of thyroid cancers are diagnosed at the localized stage. However, larger nodules, if cancerous, are significantly more likely to be follicular or Hurthle cell carcinomas (or other rare malignancies) in comparison with smaller nodules. Results were classified based on criteria and terminology analogous to those of the Bethesda System for Reporting Thyroid Cytopathology (18, 19).

We reviewed the records of 4955 consecutive patients referred to the Thyroid Nodule Clinic at the Brigham and Women's hospital from 19952009. In thyroid ultrasoundography, high-frequency sound waves pass through the skin and are reflected back to the machine to create detailed images of the thyroid. Based on surgical pathology, 927 of 7348 nodules (13%) were cancers. Thyroid cancer is commonly diagnosed at a younger age than most other adult cancers. And women are 3 times more likely to develop thyroid cancer than men. The chance of being diagnosed with thyroid cancer has risen in recent years and is the most rapidly increasing cancer in the US. It has tripled in the past three decades. Thyroid nodules. Thyroid biopsies can return various results: Treatment options will vary depending on whether thyroid nodules are found to be benign or malignant. Specifically, all thyroid FNAs were classified into one of the following categories: nondiagnostic, negative for malignant cells (benign), atypical cells of undetermined significance, suggestive of a follicular neoplasm, suggestive of a Hurthle cell neoplasm, suspicious for malignancy, and positive for malignant cells. Malignant nodules occur in roughly 5% of all nodules. Study Cohort Depicting the Demographics and Ultrasound Characteristics of 4955 Patients With 9339 Nodules 1 cm. Although women are three times more likely than men to get thyroid cancer, a similar number of men and women die from the disease each year. Most recently, a study from 2006 concluded that no association exists (10). Blood tests of thyroid levels also may provide helpful information. The hormones produced by the thyroid help the body produce energy, stay warm, and keep vital organslike the heart and brainworking properly. He or she will also check for signs and symptoms of hypothyroidism, such as a slow heartbeat, dry skin and facial swelling. Fine-needle aspiration (FNA) is the primary diagnostic methodology used for thyroid nodule evaluation. The authors declare that they have no conflict of interest.

But this varies based on the type and stage of thyroid cancer when discovered and its location. Near-total thyroidectomy may be used depending on the extent of the disease. Exposure to radiation as an adult poses less risk for thyroid cancer than in children. Nodules in the lower portion of the lobes are believed to be at least risk for cancer. Indeed, several prior investigators have argued that histologically benign nodules that harbor known oncogenic mutations (such as RAS or PAX8:PPARg mutations) may be best characterized as carcinoma in situ (24). Thyroid Nodules: Causes, Symptoms & Treatment - Cleveland Clinic Previous studies suggested that nodule size may assist in cancer risk assessment, although data are conflicting (12, 13). Notably, a threshold effect is detected at approximately 2.0 cm in nodule diameter. 2023 American Cancer Society, Inc. All rights reserved. A rare primordial odontogenic tumor in a pediatric patient. At least 85% of thyroid nodules are benign thus thyroid cancer accounts for only a small percentage of all thyroid nodules. 4. 1 They are palpable in 47% of the population and have been detected using ultrasonography in up to 67% of adults. WebMore than 90% of detected nodules in adults are noncancerous (benign), but they may represent thyroid cancer in approximately 4.0% to 6.5% of cases. Athyroid scanis a picture of the thyroid gland taken after a small dose of a radioactive isotope normally concentrated by thyroid cells has been injected or swallowed. WebMost thyroid nodules are benign, but about 2 or 3 in 20 are cancerous. Only a small percentage of nodules in the isthmus are found to be cancerous. A nodule with a benign biopsy that is stable or decreasing in size is unlikely to be malignant or require surgical treatment. For the purposes of this investigation, thyroid nodules 1.0 to 1.9 cm in diameter provided baseline cancer risk for comparison (10.5% risk of cancer). This rate was similar to nodules measuring 1 to 1.9, 2 to 2.9, or 3 to 3.9 cm (1.1%, 0.7%, or 1.5% false-negative rates, respectively), although we note that only selected thyroid nodules were subject to repeat FNA or surgical resection to define these calculations. Is nodule size an independent predictor of thyroid malignancy? Update on ACR TI-RADS: Successes, Challenges, and Future Directions, From the. Thyroid nodules are common, and prevalence increases with age (1). Accessibility This procedure is called a total thyroidectomy. Although this prevalence was increased once nodules grew larger than 2 cm, a notable finding is that the distribution of follicular and Hurthle cell carcinoma increased linearly from 6% in nodules 1 to 1.9 cm to 15% in nodules 4 cm in diameter (Table 4 and Figure 1).

Doru Paul, MD, is board-certified in internal medicine, medical oncology, and hematology. Data from 7348 evaluated nodules are presented. Investigating the effect of thyroid nodule location on the risk of thyroid cancer. 95% of solitary thyroid nodules are benign, and therefore, only 5% of thyroid nodules are malignant. Recent research has found that nodules in the thyroid isthmus pose a greater risk of malignancy than nodules in the lobes. Cystic (fluid-filled). This may hurt a little. She has a Master's degree in Health Communication and a Bachelor's degree in journalism.. Other data have demonstrated a higher rate of false-negative aspirates in larger nodules, which may reflect a clinician's ability to incorporate multiple variables (such as ultrasound and clinical characteristics) into care decisions, even if cytology is benign. Know why a test or procedure is recommended and what the results could mean. It is believed the dose is so low from these procedures that the risk is likely to also be low. The nodule is cancerous.

Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Some physicians numb the skin over the nodule prior to the biopsy, but it is not necessary to be put to sleep, and patients can usually return to work or home afterward with no ill effects. If the lesion is benign, the patient is monitored via ultrasound for the growth of the nodule or development of new nodules. During this test, a healthcare provider inserts a very thin, hollow needle into the thyroid to remove a sample of cells. Therefore, we acknowledge that a large nodule (even if cytologically benign) may require resection based on cosmetic, symptomatic, or clinical concerns alone. Ultrasounds of the thyroid use high-frequency sound waves to get a picture of the thyroid gland. Radiation treatments for cancer in childhood also increase risk. You will probably need surgical treatment if your nodule appears cancerous. Initially, a physical exam of the thyroid will be performed, when a healthcare provider will feel the neck to see whether the entire thyroid gland is enlarged, and to determine if there are multiple nodules.

In contrast, follicular carcinoma is much more likely in larger nodules. When malignant, the proportion of papillary carcinoma decreased (nodules 1.01.9 cm, 92% of cases; 2.02.9 cm, 88%; 3.03.9 cm, 83%; >4 cm, 74% [P < .01]), while follicular carcinoma increased (1.01.9 cm, 6%; 2.02.9 cm, 7%; 3.03.9 cm, 12%; >4 cm, 16% [P < .01]) as nodules enlarged. In cases that underwent surgery, the final diagnosis was based on histopathological analysis of the surgical specimen by a staff pathologist. . Greater nodule size influences cancer risk, although the increase in absolute risk between small (1.01.9 cm) and large (>4.0 cm) nodules is modest.
