Sex specific trends in lung cancer incidence and survival revealed
Lung cancer is the most common tumour type, with an estimated 1.5 million cases diagnosed worldwide every year. In most countries it has historically been more common in men, but its incidence in women is rising, following an increase in the proportion of women smokers. There is therefore considerable interest in studying differences in incidence patterns of this tumour between the sexes.
Several studies have shown that women are more likely than men to be diagnosed with adenocarcinoma of the lung, and that they tend to be diagnosed at a younger age and an earlier stage of the disease. However, most studies have been connected to clinical trials, and thus affected by the exclusion criteria set by those trials.
