In recent years, the incidence of breast cancer increased year by year, a female friend it is also a growing concern about the rate of breast popularization of knowledge, everyone recognized that it is a family of genetic predisposition. Expert survey found that 5% ~ 10% of breast cancer is a family-oriented. If there is a close relative with breast cancer, then the increased risk of suffering from breast 1.5 to 3 times; if two close relatives with breast cancer, the prevalence rate will increase by 7 times. Incidence of younger relatives, the greater the risk of breast cancer.
Breast cancer is the most common malignancy of women, one ahead of the current age of onset, the incidence rates on the rise. Of these, 5% ~ 10% of breast cancers associated with genetic mutations, most notably genes BRCA1 gene. The discovery of genetic early diagnosis of breast cancer at the molecular level may be an early to take preventive measures to reduce breast cancer mortality.
Experts through years of research found that: proportion of patients suffering from breast cancer by their parents, by specific genes (BRCA1/BRCA2 genes) inherited. These genes caused by abnormal structure or function will be the incidence of breast cancer risk to carriers is much higher than the general population. There studies have shown that about 70-85% of the BRCA1/BRCA2 gene mutation carriers, in their lifetime will develop into breast cancer patients. Less than 30-year-old woman more than 25% of breast cancers are due to a genetic mutation caused.
Experts advise: There is a family history of breast cancer, women must adhere to the regular self-inspection to detect traces of breast cancer, early treatment. Breast mass is the most common signs of breast cancer, this mass of different mass and breast hyperplasia, often as a single, irregular shape, texture hard, activity is not good, mostly no pain, no significant relationship with the menstrual cycle.
