Gene Test Results may not Provide Relief, Depending on your Family History
A new study found that the gene test commonly performed on relatives of breast cancer patients may not provide someone relief that they will not develop cancer even if that person tests free of the cancer's most common gene mutation.
The genes BRCA1 and BRCA2 are linked with particularly aggressive hereditary breast cancer and an increased risk of ovarian cancer. However, those gene mutations only account for about 15 percent of all breast cancer cases.
The study found that nearly 1,500 women from 365 breast cancer-prone families who tested negative for the BRCA gene mutations five years later had a fourfold higher risk than the average woman of developing breast cancer.
The study also found that these women didn't have an increased risk of ovarian cancer, like BRCA1- and BRCA2-carriers do.
It was really interesting that the article mentions that the BRCA tests cost about $3,000, and that's with this new evidence that family history may be a much stronger predictor.
