Breast Cancer Not Automatically inherited
For those of you women who have a family suffering from breast cancer associated with BRCA genetic mutations need not fear going to suffer the same breast cancer gene test results if they are negative.
It is about 5-10 percent of breast cancer incidence is influenced by genetics, and largely caused by abnormal genes BRCA1 or BRCA2. Women who have mutations in this gene are at risk of 5-20 times more likely to suffer from breast cancer or ovarian cancer.
Usually women with BRCA1 or 2 gene mutations are highly recommended to perform cancer screening and preventive measures to reduce the risk of breast cancer. In fact, not a few women who decided to lift their breasts or ovaries to prevent cancer.
In a recent study conducted by analyzing data on more than 3,000 families with BRCA1 or BRCA2 mutations in three countries, that is the United States, Canada, and Australia has provided encouraging results. Researchers have found that there was no evidence to suggest that women who do not have the mutated gene would be at risk of developing breast cancer.
The results of this research as well as refute the results of a 2007 study which mentions the risk of cancer remains high even if one does not carry the gene mutation in the family. Previous studies also have found that if a gene mutation found in family or other family members should also do breast cancer screening. Women who have negative test results are considered the same risk as the general population.
American Cancer Society has also been mentioned to have nuclear families suffering from cancer, such as mother, sister, or child, and then a person’s risk of developing cancer is twice as big. Meanwhile, if extended family members who suffer from breast cancer, our risk for cancer is only one-third.
