Is it possible there is a genetic component to this disease? In my family history, my grandmother, my aunt and my mother — and oddly enough, my father— all passed away as a result of CLL. Both my parents also had lymphoma. I was diagnosed in 2017 with CLL, which I’m told is currently in a slow-moving state. Does anyone else have a similar familial pattern? My doctor told me that having 2 parents die of the same 2 cancers is unusual.
