In the Dáil debate last night, Deputy Gormley quoted a WHO report which included a shocking prediction that, within the next 20 years, there will be a 50% increase in the incidence of cancer, largely due to environmental factors. It is well known that cancers occurring in the west are quite different to those which occur in China and Japan. This points directly to the conclusion that cancers are actually linked to environmental and lifestyle factors. That, in turn, raises the issue of prevention and lifestyle. We need to make greater investment and work much harder on prevention, not only in relation to smoking, although that is the more obvious issue.
