Abstract

Oral cancers in the Asir region of Saudi Arabia have been observed to occurmostly among patients who have been long-term khat users. In a survey that reviewed cancers for the past two years there were 28 head and neck cancer patients, 10 of whom presented with a history of having chewed khat. One of these was a case of metastatic cervical lymph node and unknown primary, one was a parotid tumour, and the remaining eight presented with oral cancers. All were non-smoking khat chewers and all of them had used itover a period of 25 years or longer. We conclude that this strong correlation between khat chewing and oral cancer warrants attention.
