Briefly discuss: What is cancer? How are genetic mutations involved in breast cancer? What percentage of breast cancers have mutations in BRCA1/BRCA2 genes?  What is the probability of developing breast cancer if you inherit mutations in these genes?

If there is a history of breast cancer in your family, would you get tested (or would you encourage your mother or sister to get tested)? If you/they did carry the mutation, would you consider/advise getting a mastectomy? Why? Do you think that health insurance should cover the cost of genetic testing?
