Risk gene to increase breast cancer

①Brca

Genes that know that breast and ovarian cancer can easily develop are BRCA1 and BRCA2. BRCA is an abbreviation of breast cancer sensitive gene and is one of the cancer suppression gene. BRCA abnormalities are often inherited from either parent. A mutation may be inherited by half the probability of a child born from any of the parents.

BRCA1 is known to cause breast cancer and ovarian cancer, and BRCA2 can cause breast cancer. If men have abnormalities in these gene, there is a high risk of developing breast cancer.

② HBOC

It stands for hereditary breast cancer and ovarian cancer. The milk caused by BRCA1 is a genetic milk. If a pathological mutation is found in the result of the BRCA1 and BRCA2 gene tests, it will be diagnosed with HBoc. The risk of developing breast cancer is a very high ratio of 40-90%.

However, even if the BRCA1 and BRCA2 have a pathological mutation, not everyone will have breast cancer or ovarian cancer. Some people do not develop a lifetime. However, the risk of breast cancer and ovarian cancer is high, and some people have young breast cancer and ovarian cancer frequently. Men are prone to prostate cancer.

If you are worried, get a genetic counseling. Inheritance breast cancer has a poor prognosis, easy to recur or anticancer drugs. Gene counseling can be used not only by the person but also by the family.
