INTERACTBreast Cancer ScenarioYou are David, Sonya's son: 30 years old and engaged to be married. A genetic test has revealed that you've inherited a mutation for breast cancer. Your form of the mutation (BRCA-1) means that you as a male don't have a greatly increased risk of getting breast cancer. (Men carrying a mutation in BRCA-2 have a somewhat more significant risk: about 6 percent greater than the general population.) You do, however, have a 50-percent chance of passing the BRCA-1 mutation on to your children.If your sons inherit the mutation, they will - like you - have little increased risk of getting breast cancer. If your daughters inherit the mutation, however, their risk of contracting breast cancer could be as much as 80 percent to 90 percent. Your fiancee, Susan, knows that your mother is dying of breast cancer, and that your sister has had it. What Susan doesn't know is that the problem stems from a genetic mutation. She desperately wants to have children. If you tell her, how will she react? Will she still want to get married? Should you tell your fiancee that you carry the gene? Yes, tell her. No, don't tell her. |
