Why are alcohol and tobacco use more common risk factors for oral cancer in men than women?

India has the highest global oral cancer incidence, linked to tobacco (83 carcinogens, 42.4% men, 14.2% women) and alcohol (15.8% men, 3.2% women). Synergistic effects increase female susceptibility, diagnosed later. Poor hygiene, chronic irritation, and mucosal permeability play roles.
