Hi Dmma94, so sorry about your Grandmother.  First of all, just because a cancer is aggressive this doesn't mean that the patient has no chance of survival.  Your Grandmother might still have a good few years left, it all depends on what the treatment plan is.  I guess what I am saying is don't assume the worst.  I am not going to tell you not to worry, because it is absolutely natural to worry about our loved ones when they become seriously ill.  Take the time to process this shock that you have had and take it from there...........good luck mate, to you and your grandmother, Violet, xx
