Does late marriage and late childbearing make it more likely to get breast cancer? Can heredity also lead to breast cancer?

Breast cancer is a malignant tumor with a high incidence rate in women, but many people do not understand why it happens. In fact, there are many causes of breast cancer, and they are also very common. Let's take a look at the specific content. For women who marry and have children late, estrogen will play a long-term role because they have not experienced childbirth and breastfeeding for a long time. In an environment where estrogen stimulates growth for a long time, women who marry late have a higher risk of breast cancer. Specifically, women who give birth to their first child and breastfeed before the age of 35 have a much lower risk of breast cancer than those who give birth to their first child and breastfeed before the age of 35. The reason is related to the increase in progesterone secretion after pregnancy, the fight against estrogen, and the low level of estrogen during lactation. Therefore, according to relevant surveys, in the context of the fast pace of modern life and late marriage and childbirth, especially in first-tier cities such as Beijing, Shanghai, and Guangzhou, the incidence of breast cancer is relatively high. The incidence of late or non-childbearing elderly women is 2-3 times higher than that of young women with normal pregnancy and breastfeeding. What is the cause of breast cancer? 1. Changes in dietary structure. Western fast food is very popular, the diet is gradually westernized, high-fat and high-calorie diets are increasing, fat sources, animal foods, and vegetable oil intake are significantly increased, and female estrogen levels are increasing. Therefore, doctors recommend eating more broccoli and other vegetables to balance estrogen levels, and eating more orange fruits and vegetables rich in carotene, such as carrots and tomatoes, which can help reduce the risk of breast cancer. In addition, limiting the intake of sugar and high-fat dairy products can also help prevent breast cancer. Second, the obesity rate is rising. Since estrogen is produced in fat cells, excessive fat accumulation increases estrogen production, and excess estrogen is stored in adipose tissue after lipidization, and is continuously released into the blood, stimulating breast tissue, which can easily cause breast cancer over time. Data show that being overweight or obese can increase the risk of breast cancer by 30% to 60%. Third, bad living habits. Female friends who stay up late for a long time, drink alcohol, and neglect exercise due to busy work, and do not have healthy living habits, will also increase the risk of breast cancer. Studies have shown that drinking is related to the risk of breast cancer, especially during pregnancy, and staying up late for a long time can also cause endocrine disorders. Fourth, mental stress is relatively high. Psychological stress can also cause physiological endocrine disorders, especially white-collar workers and female friends with strong career ambitions, must learn to regulate their emotions. Fifth, genetic factors. Clinically, women with a family history have a doubled risk of breast cancer. 9: Late marriage and late childbearing are high-risk factors for breast cancer. Many people do not work as early as those born earlier, which leads to the occurrence of breast cancer, so they still need prenatal and postnatal care. Giving birth at the appropriate age is good for both mother and child.
