Do you know anyone positive for the BRCA gene who doesn't have a family history of breast cancer?

As far as I know the only women who get the test for the BRCA gene have family histories. Women with family histories already know they are at increased risk. I know women who have multiple women in their family who died from breast cancer, and they eventually got breast cancer themselves, and are negative for the gene.

I have no problem with gathering more info about breast cancer, for both the patient and the researchers, but women with family histories don’t gain much info, except that it might help them make decisions about treatment. I could see where it would really help women with no knowledge of family history.
