Modifiable risk factors for thyroid cancer: lifestyle and residence environment

Abstract

In recent years, there has been a rapid increase in the prevalence of benign and malignant tumours of the thyroid gland worldwide, positioning it as one of the most prevalent neoplasms within the endocrine system. While the pathogenesis of thyroid tumours is still unclear, an increasing number of studies have found that certain lifestyle and residence environments are associated with their occurrence and development. This article endeavours to elucidate the correlation between lifestyle, residential environment, and the increased prevalence of thyroid cancer in recent years. It specifies the frequency of the lifestyle and outlines the scope of the residential environment. It also endeavours to summarise the main mechanistic pathways of various modifiable risk factors that cause thyroid cancer. Factors that prevent thyroid cancer include smoking and alcohol consumption, quality and regular sleep, consumption of cruciferous vegetables and dairy products, and consistent long-term exercise. Conversely, individuals with specific genetic mutations have an elevated risk of thyroid cancer from prolonged and frequent use of mobile phones. In addition, individuals who work in high-pressure jobs, work night shifts, and live near volcanoes or in environments associated with pesticides have an elevated risk of developing thyroid cancer. The impact of living near a nuclear power plant on thyroid cancer remains inconclusive. Raising awareness of modifiable risk factors for thyroid cancer will help to accurately prevent and control thyroid cancer. It will provide a scientific basis for future research on lifestyles and living environments suitable for people at high risk of thyroid cancer. (Endokrynol Pol 2024; 75 (2): 119-129).
