Abstract
The author has investigated the epidemiology of oral and pharyngeal cancer in several different countries and localities in Central and South-East Asia. From comparisons of the various countries and areas and from detailed case studies among oral-cancer groups and control groups, the author has obtained strong supportive evidence for the association of the disease with the habit of chewing tobacco. He has also found a less marked association with smoking, the drinking of alcohol, and vegetarian dietary customs.
