According to tumor, node and metastasis (TNM) staging system, 43% patients were at stage IV, trailed by 32.5% at stage III, 18% at stage II and 7.5% at stage I respectively. The toxic habits like chewing of smokeless tobacco, smoking, gutkha, betel quid and chalia were found associated with HNCs and the most affected organs were the tongue (22%) and larynx (18.5%). The association between HNC and occupation showed that 18.5% patients worked in factories where they might be exposed to risk hazards like cement, wood dust, formaldehyde, asbestos, benzene and coal. The results with respect to cast system showed that Jutt, Sheikh and Khan were affected (17.5%, 16% and 15%, respectively) more than any other cast.
