Untreated High Grade Invasive Tumour

My Dad died on Saturday night. While trying to find information on advanced bladder cancer I found very little on how someone actually dies with this disease. Just in case there are others searching for this information I would like to share how the end came. I am not going to go into the details. I just want to share what seems to me to be the most important facts. My Dad had home hospice care and he died in his sleep. It was very peaceful, painless and kind death. Of course it was heartbreaking for those of us with him but it was also a beautiful moment. I wanted to share this with you as I had all kinds of horrible fears that proved groundless. I hope this is of some comfort to somebody else. God bless you all.

Hi, about six months ago my 88 year old Father was diagnosed with a high grade invasive bladder cancer. Unfortunately his general health also took a turn for the worse. Over the last six months he has been in and out of hospital with recurring chest infections. He has become very frail. Because of the chest infections he has not been able to have any treatment for the cancer. So his cancer has been left untreated for six months. Now he is bleeding quiet heavily, almost every day, and he is starting to have some pain on urinating. His urologist has recommended that he receive palliative care. He has had a scan done and the palliative people are going to have a look at it. I know that there is little point in second guessing whatever the scan reveals – but I can’t help trying to make sense of what’s going on. This is my first post here but I have been an avid reader of this forum and find it to be a wonderful source of hard won information.
My question is this: what is the likely future for my Dad and what times scale should we be looking at?
