The fastest growing malignant tumor - Thyroid Cancer!

By: HSEclub NewsJul 23, 2025

In recent years, the incidence of Thyroid Cancer has increased significantly, becoming one of the fastest growing malignant tumors. What causes the increase in the incidence of Thyroid Cancer? How should we deal with this disease?

The rapid increase in the incidence of Thyroid Cancer is the result of the combined effect of multiple factors.



01. The innovation of detection technology is the first to bear the brunt

With the continuous advancement of ultrasound technology, high-resolution ultrasound can detect tiny thyroid nodules at the millimeter level, making it possible to diagnose early Thyroid Cancer that was originally difficult to detect. In the past, many tiny thyroid lesions were not discovered due to limited detection methods. Now, with the enhancement of physical examination awareness and the popularization of detection technology, the detection rate of Thyroid Cancer has increased significantly, which has "pushed up" its incidence data to a certain extent.


02. Changes in lifestyle are also an important cause

Modern people have been in a fast-paced, high-pressure life for a long time, and negative emotions such as long-term mental tension, anxiety, and depression frequently occur. Long-term mental stress can affect the normal function of the human endocrine system, and the thyroid gland, as an important endocrine organ, is the first to be affected.

Hormone secretion disorders can interfere with the normal growth and metabolism of thyroid cells and increase the risk of Thyroid Cancer. In addition, changes in modern people's eating habits cannot be ignored. Irrational iodine intake is a typical example. Iodine is an important raw material for synthesizing thyroid hormones. Excessive or insufficient iodine intake may lead to thyroid disease. Long-term iodine imbalance can stimulate abnormal proliferation of thyroid cells and may induce cancer.



03. Environmental factors also play a key role in the rising incidence of Thyroid Cancer

Industrial pollution, electromagnetic radiation, etc. These pollutants and harmful substances in radiation may cause gene mutations. For example, long-term exposure to ionizing radiation, such as areas around nuclear power plant accidents, and people who work in radioactive areas but do not protect themselves properly, will significantly increase the risk of Thyroid Cancer.


Understanding the early symptoms of Thyroid Cancer is crucial for early detection and early treatment.

The appearance of a painless lump in the neck is one of the most common symptoms of Thyroid Cancer. The lump is usually hard, with an uneven surface and unclear boundaries, and can move up and down with swallowing. Some patients may also experience hoarseness and difficulty in pronunciation, which is caused by the tumor invading or compressing the recurrent laryngeal nerve; if the tumor compresses the trachea, it will cause difficulty breathing; if it compresses the esophagus, it will cause difficulty swallowing; a few patients will also have swollen lymph nodes in the neck.


When these symptoms appear, you must pay great attention and seek medical attention in time.

In the face of Thyroid Cancer, prevention is the key "first line of defense".


  1. Maintaining a healthy lifestyle is particularly important. Keep a regular schedule, ensure adequate sleep, and allow the body to get adequate rest and recovery;
  2. Eat a reasonable diet, achieve a balanced iodine intake, avoid long-term and large-scale consumption of high-iodine or low-iodine foods, eat more fresh vegetables and fruits, and ensure balanced nutrition;
  3. Exercise moderately, insist on at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, jogging, swimming, etc., to enhance the body's immunity and maintain the stability of the endocrine system.


04. Learn to regulate emotions, release stress through meditation, yoga, listening to music, etc., and maintain a positive and optimistic attitude.

In addition, for high-risk groups such as those with a family history of Thyroid Cancer and long-term exposure to radioactive substances, thyroid ultrasound and thyroid function tests should be performed regularly to detect potential lesions in time.


The rapid increase in the incidence of Thyroid Cancer is a health issue that needs attention. Although Thyroid Cancer has a better prognosis than other malignant tumors, we must not take it lightly.

Understanding the causes of the disease, paying attention to early symptoms, and actively taking preventive measures can take the initiative and protect our thyroid health.
