My dad has advanced head and neck squamous cell carcinoma. He is no longer receiving any treatment other than medications for pain. He is at home with family caregivers and refuses hospice care. The tumors are rapidly growing and his face, neck, head, and throat are swollen, making him almost unrecognizable. He can no longer speak because his tongue takes up his whole mouth, and he has a feeding tube. He has mucus flowing from his nose and tracheostomy that has an odor that is becoming more and more pungent. My dad is sleeping most of the day, but he is restless. He also twitches and jerks the entire time he is sleeping (i found it to be myoclonus symptoms). I understand his death is nearing, but I am not sure if he has a week or two months left. I also understand that there is not really a "time frame" for determining death. My question is what are the signs that death is very close so that I may gather friends and family to say goodbye?
