It all really depends on the patient (how old they are, medical history, other cancers they have) The survival rate varies heaps and changes over time. My grandmother has recently been diagnosed with bone cancer. She also currently has liver cancer and a brain tumour, but can't recieve treatment. My mum refused to tell me how long she had to live. I think it may be a few weeks or a few months. I'll keep you posted once I actually find out.

Here is a website with a little more information on survival rates, but it doesn't tell us how long a patient will live without treatment:

Here is the National Cancer Institute homepage for bone cancer:

Hope this info can help
