The characteristics of ultrasonography for thyroid cancer include the tumor being a solid hypoechoic mass with unclear boundaries, uneven internal echoes, abundant internal blood flow, and the presence of sandy calcifications and longitudinal growth, among others. Currently, ultrasonography is the preferred method for examining thyroid nodules. It can clearly identify the number, nature, and location of thyroid nodules, as well as whether there are any abnormally enlarged lymph nodes in the neck. Ultrasonography is highly accurate in differentiating the nature of thyroid nodules, with experienced ultrasonographers reaching an accuracy rate of over 80%. However, the highest accuracy in differentiating the nature of thyroid nodules is still achieved with fine-needle aspiration cytology.

Can occasional smoking and drinking be okay with thyroid cancer?

Thyroid cancer is a common malignant tumor in the head and neck area, and currently, the exact mechanism and etiological causes of thyroid cancer are not clearly defined in the clinic. However, some research studies indicate that there are certain factors associated with the incidence of thyroid cancer. For example, ionizing radiation, prolonged exposure can lead to the occurrence of thyroid cancer. Both insufficient and excessive iodine intake can lead to a high incidence of thyroid cancer. Genetic factors also play a significant role in the development of thyroid cancer. Excessive smoking and drinking can promote the occurrence of thyroid cancer. Therefore, heavy smoking and drinking are not recommended, but occasional smoking and drinking do not significantly impact the condition of thyroid cancer and are deemed acceptable. Moreover, for patients with thyroid cancer, treatment is primarily surgical, as radiotherapy and chemotherapy are not very sensitive anti-tumor treatments.

Early symptoms and manifestations of thyroid cancer

Thyroid cancer is a common malignant tumor in the head and neck area. Early symptoms and signs primarily include a thyroid mass discovered incidentally during a physical examination. This type of mass grows quickly, leading to localized thyroid enlargement, and patients may experience discomfort when swallowing. Additionally, some thyroid cancer patients, due to abnormal hormone secretion, might experience unexplained skin flushing or sweating symptoms. Besides, early symptoms and manifestations of thyroid cancer are not typical, and many patients do not exhibit obvious symptoms. Instead, abnormalities in thyroid function are often incidentally found during physical examinations.

Differences between the symptoms of thyroiditis and thyroid cancer

Thyroiditis, if it is acute suppurative thyroiditis, clinical manifestations include fever, local pain in the thyroid, tenderness on palpation, and a hard texture of the thyroid. Examination will show an increase in white blood cells. Subacute thyroiditis may also present with mild fever or high fever and local pain in the thyroid, but compared to suppurative thyroiditis, the increase in white blood cell levels is not as significant in subacute thyroiditis. If it is autoimmune thyroiditis, there may not be obvious symptoms clinically; there may be enlargement of the thyroid, and the thyroid may feel tougher upon palpation. As for thyroid cancer, clinically, if it does not cause hyperthyroidism or hypothyroidism, there are no specific symptoms. When the cancerous tumor is large, there may be an enlargement of the thyroid, the texture of the enlarged thyroid will be very hard, and there will be notable local adhesions. Of course, the main difference can be detected and diagnosed through an ultrasound examination.

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.

Is thyroid cancer without lymph node metastasis considered early stage?

Thyroid cancer, if it has not metastasized to lymph nodes, generally falls under early-stage. Once thyroid cancer is diagnosed, surgical removal is the primary treatment choice. Postoperative treatments vary depending on the different pathological types of thyroid cancer. For the most common type, papillary carcinoma, if the surgery is radically curative, further treatment may not be necessary, and merely supplementing thyroid hormones suffices. In cases such as follicular carcinoma, undifferentiated carcinoma, or medullary carcinoma, even after surgically radical removal, postoperative treatment often requires further radiotherapy or treatment with Iodine-131, depending on the surgical pathology results. (The use of medications should be carried out under the guidance of a professional doctor.)
