Thyroid cancer, after undergoing a fine needle biopsy, may spread if surgery cannot be performed immediately, which is a risk of the thyroid cancer biopsy. Fine needle biopsy of the thyroid is a method for obtaining histopathological results and is a gold standard for the clinical diagnosis of thyroid cancer. A biopsy is an invasive examination that causes some degree of harm to the body, hence, informed consent must be obtained from the patient before proceeding. After the biopsy, complications such as local bleeding, swelling, pain, and infection may occur, and the spread of cancer cells at the biopsy site is a significant adverse effect. Therefore, for most thyroid cancer patients, it is advisable to arrange surgery as soon as possible after a biopsy to prevent the disease from spreading.

What department should thyroid cancer see?

Firstly, thyroid cancer is the most common malignant tumor in the neck area. Therefore, it is recommended to consult with the most professional oncology department for diagnosis and treatment when the disease occurs. If thyroid cancer is operable, surgery can be performed by the head and neck surgery department. After surgical treatment, if radiotherapy and chemotherapy are needed, it is still recommended to see an oncologist for treatment and specific therapies. Thus, different departments may be consulted during different stages of the disease, but the primary recommendation is still to seek treatment from the oncology department.

Causes of Thyroid Cancer

Regarding the causes of thyroid cancer, they are similar to most malignant tumors. The etiology of thyroid cancer is currently unclear, but some factors have been found to be associated with the onset of thyroid cancer. The first factor is neck radiation; the thyroid is an endocrine organ that is sensitive to radiation, so radiation exposure may cause carcinogenic changes in thyroid cancer cells. The second factor is genetics; some thyroid cancers have a clear genetic predisposition, the most typical being medullary thyroid cancer, with about 25% of patients showing familial clustering, known as familial medullary thyroid cancer. The third factor is that the rapid increase in the incidence of thyroid cancer also has some reasons, with one recognized reason being advancements in early diagnostic methods, allowing for the easy detection of numerous early lesions. The fourth is iodine intake, which has been shown to be related to some benign diseases of the thyroid, but its relationship with thyroid cancer itself needs further study.

How is thyroid cancer diagnosed?

The first point is the diagnostic process for differentiated thyroid cancer. Initially, most patients may not have symptoms, while a minority might show symptoms due to invasion of surrounding organs. Ultrasound examination is the preferred method for diagnosing thyroid nodules. Ultrasound can clarify the number, nature, and location of thyroid nodules, as well as provide information on whether there are abnormally enlarged lymph nodes in the neck. It has a relatively high accuracy in identifying the nature of thyroid nodules. Currently, the most accurate test for determining the nature of thyroid nodules remains the fine needle aspiration cytology, which has a diagnostic sensitivity of 83-92% and specificity of 80-92%, but it is not 100% conclusive. The second point is about the diagnosis of medullary thyroid cancer. Besides the tests common for thyroid cancers, additional tests for medullary thyroid cancer can include fine needle aspiration, ultrasound, and some serological tests, such as calcitonin and carcinoembryonic antigen tests.

What are the early symptoms of thyroid cancer?

Thyroid cancer is a common malignant tumor in the head and neck area. The early symptoms of thyroid cancer are highly atypical, and many patients do not present clear early symptoms. Often, patients discover painless nodules in the thyroid incidentally during physical examinations; these nodules can move up and down with swallowing motions. In a minority of cases, when the nodules of early-stage thyroid cancer are large, they can cause hoarseness or coughing and choking when drinking water. Some patients might experience intermittent, hidden pain in the thyroid area during the early stages, which often resolves on its own without treatment. Besides these, in its early stages, thyroid cancer may not present other obvious symptoms. As the condition progresses, significant clinical symptoms appear only when the tumor invades surrounding structures or metastasizes to distant sites.

Symptoms of thyroid cancer

The symptoms of thyroid cancer, the first point is the clinical manifestations of differentiated thyroid cancer. Most differentiated thyroid cancers are asymptomatic, with only occasional palpable nodules of varying sizes and textures, which can sometimes be detected in routine physical and imaging examinations. A few advanced thyroid cancers may produce noticeable symptoms due to large nodules or invasion of surrounding organs, such as compression of the trachea causing breathing difficulties, difficulty swallowing due to pressure on the esophagus, and hoarseness due to compression of the recurrent laryngeal nerve. The second point concerns the specific clinical manifestations of medullary thyroid carcinoma. The specific symptoms of medullary thyroid cancer include persistent watery diarrhea, not accompanied by severe malabsorption in the large intestine, often with facial flushing, some endocrine syndromes, and some associated conditions such as pheochromocytoma, multiple mucosal neuromas, and parathyroid adenomas.
