Nobody knows Lil how long anyone will live with this condition, I had bone cancer 3 years ago and had radiotherapy 3 times and the pain has nearly gone, mine was so bad I was paralyzed from the waist down but can now walk, 5 years ago I had breast cancer which has spread to my lungs but with treatment I'm still here! Just because your uncle has this it's not a death sentence and the older you are the slower the cancer grows ( I'm 66 ) It's not curable but with the right modern treatment it can prolong his life as you can see in my case. I'm on chemotherapy at the moment which isn't very pleasant but I know it's giving me a lot longer to live, the main thing is that your uncle thinks positive, it really helps, all the best to him.
