@sjgray Welcome to Mayo Clinic Connect! It's perfectly normal to be fearful of a condition that took someone close to you, that you might deal with the same fate. As @nancy1900 said, changing the fear element is important. Educate yourself as far as you own unique situation. Do the recommended watch-and-wait approach as your medical team advises. Live your life fully! Try not to dwell on the "what if" of it all, although your mind, like most of us will admit to, wants to charge down that path.

How are you doing today? When is your next appointment with your hematologist/oncologist?
