Résumé
Thyroid carcinoma is a common cervical tumor. Its occurrence is associated with genetic and environmental factors. The incidence rate of thyroid cancer is increasing. However, the pathogenesis and the influencing factors of thyroid carcinoma are not yet fully understood. Many clinical studies and epidemiological investigations have found that such factors as radiation exposure, female hormone metabolism, and obesity have important links with the occurrence of thyroid cancer, but its association with factors such as dietary factors remains controversial. Therefore, it is urgent to explore and validate the relationship between various factors and thyroid cancer through epidemiological studies. In order to provide reference for the prevention of thyroid cancer, this special column “Thyroid carcinoma and associated risk factors” focused on the associations of female reproductive factors and dietary factors (including intake of iodine-rich foods) with thyroid carcinoma (nodules).

Résumé
La obesidad es una epidemia multifactorial que involucra factores genéticos, ambientales y sociales. Revisaremos el efecto de la obesidad en la reproducción femenina. El tejido adiposo está involucrado en la producción de diversas hormonas relacionadas al metabolismo, la homeostasis del individuo y a su vez también en la reproducción, tanto en la mujer como en el varón. Revisaremos los diversos cambios que producen el sobrepeso y la obesidad de la mujer y las alteraciones hormonales que influyen en la salud reproductiva de la mujer.
Obesity is a multifactorial epidemic that involves genetic, environmental and social factors. We will review the effect of obesity on female reproduction. Adipose tissue is involved in the production of various hormones related to metabolism, the homeostasis of the individual and also in reproduction in both women and men. We will review the various changes produced by overweight and obesity in women and the hormonal changes that influence women's reproductive health.
