PHILADELPHIA (CBS) – Brca1/brca2 mutations have been linked to breast and ovarian cancer and news of a negative test for the gene is often met with great relief but there is some disturbing news.

A new study finds that if specific brca1/2 gene mutations are anywhere in your family, you have an increased risk of breast cancer even if you individually test negative for this mutation.

According to the research, brca1/brca2 in your family automatically means a 2.0- to 4.5-times increased risk of breast cancer compared to the general population. Nevertheless it is still important to be tested to find out the risk.
