  Yes, some people decide to have preventive mastectomy (removal of breasts) because they have genes that means they’re have a high risk of getting breast cancer. There is also the hopes of having personalised medicing in the future, which would potentially look at the genetics of individuals and treat the diseases according to the genes that have made them more vulnerable to the particular disease.
