What causes breast cancer in men?

When it comes to breast cancer, you may immediately think of women. In fact, men can also get breast cancer. However, because the probability of men getting breast cancer is relatively small, it is not noticed. So what are the symptoms of breast cancer in men, and what should we pay attention to in daily life? Let's talk about it in detail.

The cause of male breast cancer is not very clear, but it is currently believed to be related to the following factors.

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 the excessive stimulation of ovarian hormones. However, most cases of breast cancer are caused by 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. Others: Exposure to radioactive substances, local breast damage, and the use of estrogen in clinical treatment can also induce breast cancer.

According to the above introduction, we all know that there are many reasons for breast cancer. Most men do not pay attention to these details, so it is easy to get breast cancer. Men must pay more attention to their bodies in normal times. If the body shows the above conditions, they must be treated in time.

Only treatment can do it.
