I am concerned that the incidence of lung cancer among young women is decreasing to any great extent. This is an area that we need to tackle. A recent article in the New England Journal of Medicine stated that smoking is worse than sunlight in terms of the skin-ageing process. One can always identify heavy smokers, even if they gave up the habit many years before, when they come to visit one. It is known that the collagen within the skin thins dramatically in people who are smokers. We must emphasise this fact in the case of young women. When they are 18 years of age, they never think they will reach 50 years of age and that they will not want to look like a saddlebag for a camel when they do so.
