They are usually benign masses that form in the thyroid gland. These nodules are often asymptomatic and are noticed incidentally during routine examinations. However, in some cases, symptoms such as difficulty swallowing or hoarseness may occur. Iodine deficiency, hormonal changes and genetic factors may be effective in the formation of thyroid nodules. While the diagnosis process is carried out with methods such as ultrasound and biopsy, most nodules do not require treatment. However, those that are at risk can be removed with surgical intervention.
Thyroid Nodule Symptoms
Thyroid nodules are small masses that form in the thyroid gland and do not cause symptoms. However, in some cases, symptoms of these nodules may occur.
When the nodules grow, a swelling can be felt in the neck area. This swelling is usually painless, but can be uncomfortable for some people.
Nodules that reach large sizes may cause difficulty while eating or swallowing. This is due to the pressure on the esophagus.
Thyroid nodules can put pressure on the vocal cords, which can lead to problems such as hoarseness or distorted voice.
The size of the nodules can make breathing difficult. This is especially noticeable when the nodule presses on the trachea (windpipe).
Some thyroid nodules can interfere with hormone production. Nodules that are hyperactive (hyperthyroidism) lead to excess hormone production, but those that are hypofunctional (hypothyroidism) can prevent adequate hormone production.
Thyroid nodules are usually benign, but some can be cancerous. When symptoms appear, it is important to see a health professional. The doctor will determine the nature of the nodule by performing the necessary tests and recommend appropriate treatment methods. Early diagnosis is of great importance for a healthy life.
Thyroid Nodule Causes
Thyroid nodules are abnormal growths in the thyroid gland and can occur for a variety of reasons, including genetic factors, hormonal changes, and environmental factors.
Family history may play an important role in the development of thyroid nodules. Individuals with a family history of thyroid disease are at higher risk of developing nodules. Genetic predisposition leads to cellular changes that may predispose to the development of nodules.
The thyroid gland plays a critical role in maintaining hormonal balance in the body. Irregularities in hormone levels can trigger the formation of thyroid nodules.
Iodine is a vital mineral in the synthesis of thyroid hormones. Inadequate iodine intake can cause the thyroid gland to enlarge, which can lead to nodule formation. Iodine deficiency is frequently observed in developing regions.
Thyroid nodules become more common with age. Additionally, women tend to develop thyroid nodules more than men. Hormonal changes, especially in women, are another factor that affects nodule formation.
Exposure to radiation can contribute to the formation of thyroid nodules. The risk of nodules increases with exposure to high doses of radiation, especially during childhood.
The causes of thyroid nodules are various. Therefore, it is important to consult a specialist when symptoms appear. Early diagnosis and appropriate treatment methods can have positive effects on health.
Thyroid Nodule Treatment
Treatment for thyroid nodules depends on the size and type of nodule and the patient's general health. In general, if the nodules are benign and do not cause symptoms, monitoring is sufficient. However, in some cases, treatment may be required.
Small, asymptomatic nodules are usually monitored. Doctors monitor the size and development of the nodule with regular checkups. During this process, imaging methods such as ultrasound are used to evaluate the condition of the nodule.
It can also occur due to hormonal imbalances. In this case, medication is administered to regulate hormone levels.
A fine needle aspiration (FNA) may be performed to determine if a nodule is cancerous. In this procedure, a sample of cells is taken from the nodule and sent to a laboratory. If the nodule is suspicious, more detailed evaluation may be necessary.
Surgery may be necessary for nodules that grow, cause pain or difficulty swallowing, or pose a risk of cancer. Surgery usually involves removing part or all of the thyroid gland. This method is planned according to the patient's condition and the characteristics of the nodule.
For hyperactive nodules, radioactive iodine therapy may be used. This treatment reduces the size of the nodule by reducing excess thyroid hormone.
As a result, thyroid nodule treatment is specific to the individual. It should be determined under the guidance of a specialist doctor. Early diagnosis and appropriate treatment methods provide significant health benefits.
