risk for breast cancer herself?
O Yes. While there does not seem to be a genetic link with breast cancer, she has been exposed to the same environmental factors as the rest of her family
Yes. Some forms of breast cancer have been linked to a gene mutation which she may have inherited from her mother's side of the family
O No. The causes
breast cancer have not been completely identified so she is probably at no greater risk than any other woman in the population
O No. Detection of and treatments for breast cancer have improved so dramatically in recent years that it is unlikely she would develop breast cancer
