My mother, who died of ovarian cancer, was found to be a carrier of a specific genetic mutation that greatly increases the risk of breast and ovarian cancer in women. I am a man, and I have 2 daughters. What are the halachic issues involved with having a genetic test at all, and if I am tested and found to carry the mutation, what are the halachic implications of this knowledge, i.e. what can one do or not do with information of this nature?

Thank you
