Abstract

The incidence of mouth cancers among Iraqi people is reviewed from 1973-2021 in different Iraqi provinces. The incidence rates are also illustrated in relation to age, sex, site of cancer and year of registration. Incidence rate differs widely in relation to locality, age, sex and race. The risk factors for the incidence can be attributed to tobacco and/or alcohol consumption. The relationship between diet and nutrition to the risk of cancer development has been established by several epidemiological and laboratory studies. They indicated that low intake of fruits and vegetables predisposes to increased risk of cancer development. Other risk factors include genetic, sun exposure, mate drinking (tea-like beverage), viral infection, fungal infection and chronic trauma.
