Hi, Thanks for writing in. Sorry to hear the progress of disease in your mother. The period of survival in stage 4 cancer might vary from 6 months to 2 years. In the most advanced disease also a patient might be expected to survive for 6 months if her general condition is good and she is eating and drinking. Cancer is a difficult disease to treat and must be treated till the end. Your mother has a morphine port in place and therefore her pain might be taken care of. Ovary cancer usually spreads to abdomen and involves liver, peritoneum and omentum. There is also a collection of fluid in many patients. I think she is provided good care at the hospice and can survive for another 2 months as long her eating and drinking are taken care of. Her confusion might be due to many reasons including a sense of psychological distress or disease spread to the bone. Please do not worry.
