Thank you for answering Annasmom. You are so gracious. You too have been traumatized, but are so strong!
Do we know when GB was diagnosed with cancer? Probably irrelevant, but perhaps EW administered some "cancer treatment" to him and that is how they know her?
I'm sorry; I don't know this. The only information about GW's cancer we have is test results which were among GW's papers, and those were done when the illness was very advanced. Your suggestion about EW makes sense to me.
