OUCH! Cancer twice in one year!! First my heart goes out to you.
I see a little "I told you so" going on with the person you believe knows why you have cancer.
My "gut" feeling is that it is someone who is a mother type figure, either your mother, grandmother, mother n law or someone who took on a motherly role for you at one time in your life.
Let me know. How close I am or am not, meditation to follow.
