With mutations in BRCA2, the risk increases to four or five times, the same increase in risk is in women carrying mutations in another gene, BRCA1. Both genes are tumor suppressors, that is the norm, they protected the cells from being able to have those cancer. In the presence of mutations, this does not happen, and chances are that the cell crossed the critical threshold, and turn into cancer, not only will cause breast cancer, and ovarian cancer. Thousands of women belong to families with a long family history of breast cancer or ovarian cancer in these families were dying from cancer of his mother, sister, grandmother and aunt. And the fact that to date, found major gene family forms of breast cancer, gives these families an additional chance to avoid the disease.
They must undergo genetic testing. If mutations are not, it falls apart with a heavy stone “tribal curses.” If, however, found a mutation in the genes BRCA, woman should take steps to reduce the risk: take regular mammograms to catch tumors at their earliest stages. To date, genetic scan mutations in these genes included a number of government programs to combat breast cancer in many countries. After all, the earlier the identification of a mutation, the easier it is to prevent disaster and save lives!
