What are the causes of breast cancer in men?

The quality of life is getting better and better. While we are all using high-tech electronic products, we have also brought many unhealthy factors. Although the vast majority of patients with breast diseases are women, men are also likely to suffer from breast cancer. Let's take a look at the causes of breast cancer in men.

1. Familial In reports of male breast cancer at home and abroad, a considerable proportion of the cases have a family history of female breast cancer or other tumors in the family, suggesting that male breast cancer has a certain familial nature.

2. Increased endogenous estrogen Compared with female breast cancer, male breasts have no physiological activity and lack excessive stimulation of ovarian hormones. However, most patients have male breast development, endocrine abnormalities, and liver damage. Lacassegne confirmed (1932) that repeated injections of female hormones into male mice can induce breast cancer. When the liver is damaged, the liver's estrogen inactivation function decreases, resulting in a relative excess of estrogen in the body and an increase in male breast development. Some people believe that male breast development is a precancerous disease that can easily lead to breast cancer.

3. Abnormal sex chromosomes. Other studies have shown that some patients have small testicles, fibrosis and hyalinization of the seminiferous tubules. Increased pituitary gonadotropin in urine and abnormal sex chromosomes are called Klinefelter syndrome. In this case, the incidence of breast cancer is 20 times higher than that of normal men.

4. Exposure to other radioactive substances, local breast damage, and the use of estrogen in clinical treatment can also induce breast cancer.

The above are the causes of breast cancer in men. There are mainly four reasons. In order to avoid such a situation, we can effectively prevent it after understanding the above reasons. Don't always touch electronic products. The radiation they emit to us can cause endocrine disorders, various physiological diseases, etc.
