Dubai: Oral cancer is the sixth mostcommon cancer reported globally with roughly two thirds ofthese reported in developing countries, according to a report. Regardless of nationality, roughly half of long-termsmokers will die from the effects of tobacco smoking, be itoral cancer, lung cancer or cardiovascular disease.
"There is a myth that smoking through a Shisha pipeis safer than smoking cigarettes but this is almost certainlynot the case. Several recent studies have indicated thatShisha smokers actually inhale more of the cooled smoke thanwould a cigarette smoker thereby increasing their exposure tocarcinogens within the smoke," he said. To an ever greater extent, human papilloma virus(HPV) is a causative factor in cancer of sites in theoropharynx such as the tonsil or the base of the tongue,although HPV related cancer is much less common within themouth itself. Approximately two thirds of cancers of the base oftongue and tonsil are caused by HPV and 80 per cent of thesecases occur in men. "There is no relationship between either smoking oralcohol intake with the HPV associated oropharyngeal cancer.Fortunately, HPV associated oropharyngeal cancer actuallycarries a much better prognosis than does a cancer inthis location that is not associated with HPV. Althoughresearch is ongoing, the reason for this is as yet unclear,"Dierks said. The early diagnosis of oral cancer is extremelyimportant because not only is the prognosis significantlybetter for early stage cancer, but the treatment involved isoften less extensive, Dr Dierks said.
