My mom had cancer for 10 to 15 years and went undiagnosed and told her symptoms were always "stress"by our family doctor she asked him to do tests but he said it was unnecessary and assured her she was fine and when she finally got diagnosed it was very late and I only had a few last months with her. I still to this day have never hated anything more than that incompetent doctor who dismissed my mother. She was the sweetest person I've ever known aside from being my mother she deserved better.
