Hello Fraya.  I am not surprised that you do not feel which way to turn after the events of the last couple of years.  As your mum is responding well and her tumours are reducing  that sounds like good news in terms of time but - as Moderator Steph says - we cannot be more specific as we are not medically trained and also every patient reacts differently to treatment even with the same conditions.  Please do not tie yourself in knots over this but make the most of the extra time your mum has been granted, no matter how long or short it is.  Create memories (perhaps a memory book if you think it appropriate) and enjoy being able to be with and care for your mum no matter how long or short.  Please also come and chat with us as you go through this time;  we would be so pleased to hear how your mum is doing and also how you yourself are coping now and have been coping over the last couple of years.   Take a deep breath and ask the questions for which you need answers from the medical staff treating your mum.  Annie
