The average life expectancy for somebody with lung cancer is variable, and it depends on the T and M staging for your lung cancer. Overall, for all stages combined, the overall life expectancy is about 13 %. So that's a very low figure, but if we look at some of the earlier stages, for instance stage 1A, these patients have a five year survival of anywhere between 60% to 80%. So it's a large spectrum; the prognosis depends very much on your disease stage.
