Breast cancer cluster
I have several relatives with breast cancer. Sister 1 (40yo), sister 2 (53yo), sister 3 (56yo), Paternal cousin (60yo), partneral aunts x 2 - all diagnosed with BC and of which three have died. The family has been tested for BRAC1 and BRAC2, with a negative result. So, plenty of BC in the family and no idea why. Now at the age of 53 I have decided to have a bilateral mastectomy and reconstruction.
Is there anyone out there with a family BC cluster and negative results to genetic testing ?
