Several years ago, I learned that I carry an abnormal variation of the BRCA1 gene, which is responsible for most hereditary breast cancers. I confided in several of my coworkers at the time. I've since decided that I'm going to try to have children, so I've postponed surgical options to lower my risk but have frequent medical appointments to make sure I'm healthy. My problem is my manager: One of my coworkers told her about my condition (they're friends), and now that Angelina Jolie has announced she also carries this mutation, my manager will not shut up about it. I feel really upset that my privacy is being violated, but I'm also concerned that the company now knows I will need several surgeries and have a high risk of cancer, which makes me a real liability. Is there anything I can do about this?
