The only information I found about family history of breast cancer:
"Breast cancer risk is higher among women whose close blood relatives have this disease.
Having one first-degree relative (mother, sister, or daughter) with breast cancer approximately doubles a woman's risk. Having 2 first-degree relatives increases her risk about 3-fold."
This means your grandmother and great-grandmother would not be associated with a much higher risk of breast cancer for you.
Let us know if we can help you find any additional information!
