Causes of cysts on the neck

There are many lymph nodes on the neck, so many people develop cysts on their necks due to various reasons. When a cyst occurs, many people are particularly worried that there is a problem with their lymph nodes. Therefore, many patients with cysts on their necks want to fully understand the causes of the cysts. The following is a specific answer so that you can have a comprehensive understanding.

The exact cause of this disease is not yet clear, but it is generally believed that:

(1) Excessive or insufficient iodine intake

In areas with iodine deficiency or endemic thyroid tumors, the incidence of thyroid follicular tumors is higher, and the iodine content is higher.

The incidence of papilloma is high in the region.

(2) Ionizing radiation

Internal irradiation of the head or bright irradiation can cause thyroid tumors

(3) Serum thyroid stimulating hormone (TSH) level

Feedback hypothyroidism is caused by iodine deficiency, thyroiditis, thyroid surgery, and thyroid receptor radiation.

As the body's TSH secretion increases, the risk of thyroid cancer also increases.

(4) Genetics

Goiter and thyroid cancer both have a clear familial tendency.

2. Pathogenesis of thyroid cysts and simple goiter

The main causes of this disease are:

(1) Iodine deficiency or excess in the water and soil in epidemic areas.

(2) Increased iodine requirement (due to growth and development, breastfeeding, cold, infection, poisoning, emotions, etc.).

(3) Goitrogens (cassava, radish, cabbage, thiouracil, thiocyanate, para-aminosalicylate)

sodium butazone, potassium perchlorate, cobalt, lithium salts).

(4) Drinking deep well water (containing excessive sulfur hydrocarbons, calcium and fluoride), the water source is contaminated by bacteria.

(5) Familial congenital thyroid hormone synthase deficiency. Thyroid tissue has a strong ability to concentrate iodine.

The human thyroid gland requires 60-80ug of iodine every day to produce physiologically active thyroid hormones. In vivo

There is a relationship between thyroid hormone secreted by the thyroid gland and thyroid stimulating hormone (TSH) secreted by the pituitary gland.

In a mutually dependent and mutually restrictive feedback relationship, when iodine is deficient, thyroid cells cannot synthesize enough iodine.

Thyroid hormone, blood thyroid hormone concentration decreases, thyroid hormone inhibits pituitary secretion (TSH)

The production function is weakened, the secretion of pituitary TSH increases, the TSH level in the blood increases, and the thyroid gland hypertrophy and hyperplasia is caused.

Cysts on the neck are a particular concern for many patients, who worry that malignant cysts may occur and cause serious harm to their bodies. The above content is a comprehensive introduction. Patients with cysts on the neck must have a comprehensive understanding of the above content, and then go for examination in a large hospital, and then receive correct treatment to make the cysts on their neck disappear as soon as possible through treatment.
