Women are twice as likely as men to develop lung cancer among nonsmokers.
Notes on verification
Multiple independent sources (medical institutions, cancer research foundations, peer-reviewed studies) corroborate that nonsmoking women have roughly 1.5-2x the lung cancer incidence of nonsmoking men. Exact multiplier varies by study (1.57x to over 2x), so 'twice' is an approximation but well within the supported range.
