How long he has left to live ?
[|AI|]  Hi, Thanks for writing in. The longevity for people having bladder cancer that has spread to bones is about 2 years. Since his first chemotherapy was a month back, it is important to discuss the medicines with his doctor. He might require more aggressive treatment for longer survival. With better care and treatment some patients might live longer even with cancer spread to bones. Please try and maintain his general condition such that he is able to withstand the chemotherapy and delay progress of the condition. He should also be given pain relief. Please do not worry.
