In males and females, the incidence of oral tongue cancer (C02) significantly increased [APC of 2.2% and 4.1%, respectively (<italic>P</italic> < 0.05)]. This increase in oral tongue cancer incidence was most prominent in the younger age group (<40 years, APC = 6.1%, <italic>P</italic> < 0.05).

The 5‐year RSR improved from 42.7% (1993–1995) to 59.5% (2006–2010), corresponding to an increase of 16.8% from 1993 to 2010 (<italic>P</italic> < 0.05).</p> </sec> <sec id="odi12251-sec-0004" sec-type="section"> <title>Conclusion</title> <p>The incidence of oral cavity cancer in females increased, whereas it stabilised or decreased in males.
