Hi can anyone help my husband has gm grade 4 brain tumor and has had surgery, radiotherapy and chemotherapy but the tumor is still growing. He was diagnosed in May 2015 and I know prognosis is not good about 1 to 2 years but how will I know when the time is coming , will it slow and painful or will it be quick and painless. If anyone else has experienced this please help me to help him when the time comes. He is so strong and brave and I am trying to be the same but a title knowledge for the future might help.
