The end seems to be getting near.

My mother-in-law was diagnosed with primary peritoneal cancer approximately four years ago. She had no surgery but did have chemo and she started to get markedly better and went into remission. The cancer returned several times and she did respond with less time between recurrences. Since last May she has not responded to treatment and is now in pre-hospice. She does not have pain, but the ascites is really bad. She has a peritoneal catheter and this seems to help, but her legs are still very swollen and hard. She is now getting much more weak and tired. She now walks with a walker and has a chair that is motorized to get her in a standing position. She is 85 hears old, but was really doing quite well until Sept. of this past year. She was still driving and then the ascites started to really get bad. We are taking it one day at a time, but I don't know how this terrible disease ends. Her doctor said she will just get weaker and weaker and then not be able to take care of herself. Can anyone tell me anymore? She wants to stay as independent as she can. She does know that she is terminal, but does not want to be considered full-fledge hospice. Thank you.
