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 are the early symptoms of thyroid cancer?

The most common clinical symptom of thyroid cancer in its early stages is an abnormal lump in the neck. Additionally, some patients may experience symptoms related to abnormal thyroid function. Thyroid cancer is currently a malignant tumor with a relatively high incidence rate globally and in China. There are four pathological types of thyroid cancer: papillary carcinoma, follicular carcinoma, undifferentiated carcinoma, and medullary carcinoma. Among these, papillary carcinoma is the most common and has the best prognosis. For patients presenting with an abnormal neck lump and thyroid function abnormalities, the diagnosis of thyroid cancer should be considered. Diagnosis can be confirmed through tissue obtained by biopsy or surgical excision for pathological examination. For patients with confirmed diagnoses of thyroid cancer, surgery is the preferred treatment method.

The Differences between Thyroiditis, Hyperthyroidism, and Thyroid Cancer

Thyroiditis, hyperthyroidism, and thyroid cancer are clinically distinct conditions. Thyroiditis refers to inflammatory changes in the thyroid, either autoimmunity-related, suppurative or due to inflammation. Hyperthyroidism broadly refers to a functional change, which can result from various thyroid changes caused by diseases, including external damage and inflammation, leading to symptoms of hyperthyroidism. However, these manifestations should not be confused with each other, with the latter more closely related to autoimmune thyroiditis. Thyroid cancer, on the other hand, is a malignant alteration that also occurs in the thyroid gland but is not closely related to thyroiditis or hyperthyroidism. Generally, thyroid cancer is malignant, while thyroiditis and hyperthyroidism are benign, chronic conditions.

Does hypothyroidism lead to thyroid cancer?

Hypothyroidism and thyroid cancer are two different types of thyroid diseases; hypothyroidism does not cause thyroid cancer, and there is no necessary connection between the two. Hypothyroidism refers to a decrease in thyroid function levels, caused by abnormalities in the secretion and synthesis functions of the thyroid, closely related to disorders of the endocrine system. In contrast, thyroid cancer is a change in tissue nature due to malignant transformation in thyroid tissue cells, it is not related to the thyroid's endocrine functions, and currently, there is no research indicating that hypothyroidism increases the likelihood of developing thyroid cancer. Patients with thyroid diseases should undergo dynamic thyroid ultrasonography and monitoring of thyroid function to further clarify their condition.

Is a hypoechoic area definitely thyroid cancer?

A thyroid nodule underwent an ultrasound B-examination and showed hypoechoic features, but this does not necessarily indicate thyroid cancer. It is essential to conduct relevant tests to determine the cause. For such thyroid nodules, it is first important to check their specific size. If there is concern about the presence of a malignant tumor, it is advisable to perform a fine needle aspiration for pathological examination to confirm the diagnosis. If the thyroid nodule exceeds one centimeter and causes local pain or affects surrounding blood vessels, leading to symptoms of compression, it is recommended that patients should promptly undergo surgical removal for treatment.

Early symptoms of thyroid cancer

Differentiated thyroid cancer often has no symptoms in the early stages, with only incidental palpation of nodules of various sizes and textures on the front of the neck. Some patients may find abnormalities during routine physical examinations through imaging studies, and symptoms may appear only in the later stages. The second point concerns the characteristics of medullary thyroid cancer, which exhibits specific symptoms early on, such as persistent, watery diarrhea. Additionally, this cancer involves an endocrine syndrome, where tumor cells secrete calcitonin and adrenocorticotropic hormone, potentially leading to facial flushing, elevated blood pressure, and reduced blood calcium. This may be associated with other conditions such as pheochromocytoma, multiple mucosal neuromas, and parathyroid adenomas, which can also cause corresponding symptoms.
