Is there any other genes to look for that relate to beast cancer other than BRCA 1 and 2?
I don’t know the answer to this, but I suspect there are ones we don’t even know about. I had a friend who died of breast cancer at age 29. Her mother and aunt also had breast cancer, but she did not test positive for any of the known genes linked to breast cancer.
Yes, there are more genes associated with breast cancer than BRCA 1 & 2. Go to snpedia.com and search for Breast Cancer.
