Please help. My gran suffered from cancer for a while, went through radiotherapy as she wouldn't survive anything else. She never went into full remission but was told it could be. We got told last week that the cancer is back and there most likely won't be any treatment available now, looks like this is it. What my main concern is is that my mother, grans daughter, has been asked to sign a DNR. We haven't been told a time line anything except that it's back. Can we be asked to sign a Dnr without another doctors opinion?
