Lung Cancer
Sex and Gender-based Analysis of this topic Definition Lung cancer is the leading cause of cancer death in both Canadian women and men [1]. Tobacco smoke is the most common risk factor of lung cancer, followed by indoor exposure to radon gas especially in radon rich areas and second-hand smoke exposure [2]. The combined number of lung cancer cases for both men and women (23,400) is less than the number of prostate diagnoses (25,500) in men, but more than the number of breast cancer diagnoses (22,700) in women [1].
