Genetic breast cancer is not sensitive to the issue of breast cancer families from many facts to prove that the incidence of breast cancer is the existence of tendency of family history. Clinical often visible in the mother of breast cancer and breast cancer in daughters are opportunities than women to be more than 2-3 times, and age of onset about 10 to advance. The incidence is even more common among sisters Obviously, if the mother suffering from breast cancer, while the mother is a sister of breast cancer, then his daughter in the risk of breast cancer before the age of 40 of the dangers of breast disease than no family history of the proportion of women suffering from breast cancer 40-50 times higher. If the previous generations are suffering from bilateral breast cancer and their descendants risk of breast cancer than the proportion of families with unilateral breast cancer three times higher, the general women 6-9 times.
In fact, breast cancer is not genetic, and the high incidence of breast cancer families, is the human genetic factors on the incidence of breast cancer by various indirect effects of what happened. Therefore, in patients with hereditary breast cancer is not on the tumor itself, but a tumor susceptibility. On this basis, exempt from the environment, diet, psychological state, endocrine status of a combination of factors such as the impact is a more ordinary people are more likely to have tumors. In short genetic breast cancer will not directly or indirectly there is the susceptibility, is continuing exploration and research.
