@gprior, I might also add that you don't have to navigate this alone. You can talk to a genetic counselor. Genetic counselors have advanced training in genetics and counseling. Their background enables them to provide education about genetic diseases and testing AND emotional support as you process information and make decisions.

Here's more information from Mayo Clinic to learn more about the services they provide:

You might ask at the cancer center where your husband was treated if you could speak to a genetics counselor to talk about how to talk with your family. How are you doing?
