Researchers develop gene test that will give more detailed information on risk to women with BRCA1 and BRCA2 mutationsA genetic test that accurately predicts the risk of developing breast cancer could soon be used on high-risk groups. Researchers behind the test say it could reduce the number of women choosing pre-emptive mastectomy surgery as they will be able to make more informed decisions about their care. The blood test looks at 18 genetic variations, or single-nucleotide polymorphisms (SNPs), known to affect the chances of getting breast cancer. A breast cancer charity described the more tailored approach as an exciting development. “This new test will help women at risk of familial breast cancer to make more informed decisions about their care,” Evans said.
