Out of the 67 patients, 41 were male and 26 were female. The mean age was 59.2 years (range 36 to 81) for men and 58.7 years (range 19 to 86) for women. The most common cancer site was oral cavity (34.3%), followed by larynx (25.4%), oropharynx (11.9%), nasopharynx (11.9%), hypopharynx (10.4%), lip (4.5%), and nose (1.5%).
Regarding lifestyle habits of the entire study population, 20 patients (30%) chewed betel only; 19 patients (28%) chewed betel and smoked tobacco; 19 patients (28%) chewed betel, smoked tobacco, and consumed alcohol. Two patients smoked tobacco and drank alcohol, two smoked tobacco only, two had none of the risk factors, and information was unavailable for three patients.
