If a woman with a strong family history of breast and
ovarian cancers tests negative for the BRCA1 / 2 genes, that does not mean her relatives are not at risk, says Daly — her siblings could still carry the gene, or there could be additional genes present that predispose them to cancer that clinicians don't yet know how to test for.
