I’m sorry you know so much about cancer now…. it is amazing though how Cancer is not the diagnosis it was 20 years ago. Between the development of new and better drugs and other treatment options (like gamma knive) and all the research they are doing on cells (the genome project and all the outcomes) to study the genetic markers, on-off switches and such… Stage 4… where my sister also is… they call it manageable. Like a chronic disease. Your mom and my sis will probably outlive us all!! xoxoxo
