It is noteworthy that the number of women with thyroid cancer is about three to four times higher than that of men. Why does thyroid cancer particularly “favor” women, especially young and middle-aged women? It is related to the hormonal changes in women’s bodies during puberty and childbirth, as well as endocrine disorders during menopause. Female hormones, including estrogen and progesterone, are involved in the development of thyroid cancer, and the higher the level of estrogen in the body, the more it contributes to the development of thyroid cancer. Women have more estrogen in their bodies than men, plus women in their 20s and 40s are in their prime and have the highest level of hormones in their bodies throughout their lives, so women are the majority of thyroid cancer patients at this stage. The thyroid gland is located in front of the neck, below the laryngeal nodes and on both sides of the trachea, and is an important endocrine organ of the human body. The difference in the physiological functions of the thyroid gland between men and women is also related. In our daily life, especially women should do a good job in preventing this disease, pay attention to the consumption of iodine in our life, and when we find a lump in our neck, we should go to the hospital in time for examination and early treatment to reduce the unnecessary trouble it brings to us. Therefore, it is recommended that all women pay more attention to the following aspects: 1. Do not conduct frequent non-essential radiological examinations. 2.Balanced diet, low-fat diet, less hormone-containing food, and more exercise. Both iodine deficiency and excessive iodine intake can trigger thyroid disease, so iodine-free diet or blind iodine supplementation are undesirable. Iodine intake should be adjusted according to one’s own thyroid function, living environment and dietary habits. 3. When taking some medications that may affect thyroid function, consult a relevant professional doctor to adjust the type or dosage of the medication. 4. Maintain reasonable work and rest habits, regulate your emotions and learn to release psychological stress.
