Cancer knows no politics.  Mazie and all similar are to be celebrated and supported for their striving and will to live.  There is nothing more valuable to us all than, not only our, but also, everybody else's living lives on Earth.  Because the spirit body is also adversely affected, which in turn affects one's material body, MDs can hardly perfectly state the future.  MDs have no concept of the spirit body.  Only that when the spirit body is absent, then the material body dies.  If medical science can't absolutely guarantee future, no patient can.  Notably, many cancer patients live longer than the many more noncancerous motorists dying on the nation's streets every day.  Rather than angst over Mazie's cancer prospects, just pray for her safety on America's roadways.
