RII¼0.39e0.58) . For females, SEI begins at 20e24 years (RII¼0.27) with pronounced inequalities at 60e79 years and peaking at 65e69 years (RII¼0.30e0.48). All four morphology groups demonstrate inequalities for lung cancer. For cervical cancer, squamous cell carcinoma dominates; in oesophageal cancer, squamous cell carcinoma followed by adenocarcinoma and ultimately other morphologies show inequalities. For head and neck cancers; hypopharynx, piriform sinus and larynx followed by lip, oral
