Question

You are worried about sharing your suspicions with Lee and Grace, but for different reasons. Grace, who is still recovering from breast cancer surgery and chemotherapy, seems very fragile as well as distraught that her son has a tumor-like growth. If Lee did, in fact, inherit a faulty gene from her that will predispose him to cancer, you are worried about how Grace will handle the news. She seems at great risk for deep feelings of guilt and serious depression. Lee, on the other hand, is a very upbeat young man with a great sense of humor. He seems mostly concerned about improving his mother’s spirits. You would dread being the one to tell him if it turns out that he has a genetic condition that will predispose him to various types of cancers for his entire life. In order to best communicate the pros and cons of genetic testing to them, you review the different types available.
