Is breast cancer hereditary?

Is breast cancer hereditary? Breast cancer is one of the most common malignant tumors in women. What are the concerns of breast cancer patients and their families? It is nothing more than the question of whether breast cancer is hereditary. Today, the following article will answer the question of breast cancer hereditary. Let's take a closer look!

Is breast cancer hereditary? Clinically, genetic factors do play a role in the occurrence of breast cancer.
In recent years, some studies have found that the incidence of breast cancer in people with a family history of breast cancer is about 3 times higher than that of ordinary people. In addition, some people have found that the incidence of breast cancer in female relatives of breast cancer patients is higher than that of the general population, and the average age of breast cancer in the second generation of breast cancer patients is about 10 years earlier than that of the general population. However, it should be emphasized that breast cancer is not directly inherited, but a kind of "cancer quality" inheritance, which is the genetic susceptibility to breast cancer (i.e. the risk factor for breast cancer), not breast cancer itself.
Is breast cancer hereditary? This means that breast cancer is not an inevitable hereditary disease, and relatives of breast cancer patients may not necessarily develop breast cancer. They are just more likely to develop breast cancer than the average person. The occurrence of breast cancer is also related to other factors, such as fertility, diet, and endocrine system. Only when multiple factors work together can breast cancer occur. Clarifying these has two guiding significances for people with a family history of breast cancer: on the one hand, they should avoid unnecessary fear and mental burden, and realize that breast cancer is not directly inherited;
On the other hand, we should pay attention to the prevention of breast cancer and take some preventive measures such as regular breast self-examination. If you find a breast lump, you should see a doctor as soon as possible, which is conducive to the early detection, early diagnosis and early treatment of breast cancer, and can improve the cure rate. This is very meaningful for people with a family history of breast cancer.
