Wow, did your mom say why she refused treatment?
She was told, before I was even born, that if they open you up the air makes cancer spread. She always believed crazy stuff. Then she believed any radioactive treatment would kill you, and that it was contagious. My dad had radioactive treatment once, and she told him he couldn’t go home from the hospital. I told him he could stay with me, but he wanted me to take him home. She wouldn’t even speak to me or him. After awhile, I asked him if he was going to be ok or if he wanted to go home with me, but he stayed and I kept checking on him. She didn’t speak to us for a long time.
My mother was not mentally stable, and could be very mean.
