I had my DNA tested last year at 23&Me, also for exploring the family tree, at the request of my four sisters. They have also found more relatives and much about our ancestry. It said I am more likely than most to metabolize caffeine poorly, which I do, have a good memory, which I do, and have cancer, which I did. All the mail from 23 & Me goes to my sister and she hasn’t mentioned anything else.
Sorry to hear about your medical condition. Hang in there ...
