Janlow,
There are definitely treatments for bone mets! The sooner he can get treatment the better. Please tell your husband about what is going on with his body. He needs to know so that he can make informed decisions about what he wants to do. Talk to the oncologist - quickly about treatment options. There are very good treatments available for bone mets. If you wait, or do nothing, he will decline in health quickly (possibly losing leg function, bladder & bowel function, bone fractures, and pain). So please, please get him treatment now!
I've spoken to several cancer patients who've had bone mets to the spine. They've received treatment and are doing very well now.
Keep us posted!
