Cancer. It sucks. I have gone through the process of dealing with it with my own mother, three times. However after a long battle she somehow managed to escape out the other side okay. I am sorry to hear about your own mother's terminal diagnosis. I know just how much this disease sucks. Trying to do something about it, to help people suffering from it has been something that has driven my entire life (it's why I chose science as a profession). I am sorry for your loss. I am sorry for what your mother must now be suffering through. I am sorry for the pain you will be forced to experience because biology sucks, and scientists are not smart enough to find solutions. I wish you strength.
