My mother has small cell lung cancer. She was diagnosed 10/30/09. 9 weeks ago she was released from her cancer doctor and placed with Hospice. It was only 2 days when she became bedridden. Things have been rather calm up until a couple of days ago. She is experiencing more pain and is swelling around her neck and she has spots appearing on her arms and neck. What your professional opinion about length of time until she passes away?
