What is thyroid cancer?
Thyroid cancer is a malignant tumor originating from thyroid follicular epithelial cells or parafollicular cells and is the most common malignancy of the endocrine system. Its development may be associated with multiple factors, including demographic characteristics, environmental exposures, and genetic and epigenetic alterations.
Main types and classification of thyroid cancer
1.Papillary carcinoma
The most common type, accounting for the vast majority of cases; papillary microcarcinoma (<1 cm) generally has an excellent prognosis.
2.Follicular carcinoma
A differentiated thyroid carcinoma with a relatively favorable prognosis.
3.Medullary carcinoma
Some cases are hereditary; prognosis is poorer than that of differentiated thyroid carcinoma.
4.Anaplastic carcinoma
Highly aggressive type with rapid progression and a poor prognosis.
Etiology of thyroid cancer
1.Ionizing radiation exposure
A history of head and neck radiotherapy or nuclear radiation exposure is a well-established risk factor.
2.Genetic factors
Relevant hereditary syndromes and a history of disease in first-degree relatives increase risk, particularly for medullary carcinoma.
3.Abnormal iodine intake
Both iodine-deficient and iodine-excess regions have disease occurrence, related to the spectrum of thyroid disorders.
4.Obesity and metabolic syndrome
Excess body weight and metabolic dysregulation are positively associated with thyroid cancer risk.
5.Sex and hormonal factors
Incidence is significantly higher in women than in men; estrogen may be involved in tumorigenesis.
Prevention and health maintenance for thyroid cancer
1.Avoid risk factors
Avoid unnecessary radiation exposure, maintain appropriate iodine intake, and control body weight.
2.Regular screening and self-checks
High-risk populations should undergo regular ultrasonography, and daily “look-and-palpate” self-checks are recommended.
3.Healthy lifestyle
Maintain a balanced diet, engage in moderate physical activity, and sustain a healthy psychological state.
Conclusion
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that the incidence of thyroid cancer continues to rise. Effective evidence-based prevention and control strategies require minimizing exposure to radiation and other risk factors, expanding screening initiatives in high-risk populations, and adopting individualized treatment approaches—including surgery and targeted therapies—tailored to tumor subtype and disease stage, ultimately leading to substantial improvements in prognosis.
