I would like to thank all the witnesses for coming here and being at the committee this afternoon.
The first question I have is for both Dr. Wheatley-Price and Dr. Leighl. I want to go back to statistics. I understand you already mentioned that the majority, or 85%, are smokers, and from what I know, in that group the numbers are more or less equal for men and women. However, in the non-smokers group, I understand that the numbers of women who get lung cancer are higher than those for men. I don't know whether my figure is correct, but I heard about 50% more women than men get lung cancer among non-smokers. I might be incorrect there.
Is there any indication as to why that is so? Have there been any breakthroughs on this issue?
