title: Mouth cancer in India: a new epidemic?
abstract: Oral cancer has been traditionally described as a major form of cancer in India although on the basis of cancer registry data, it was thought that the incidence has decreased. There are several recent reports in the literature, however, predicting an increase in mouth cancer incidence in India. This prediction is based upon observation of an increasing prevalence of oral submucous fibrosis, especially in younger individuals, caused by gutka, an industrially manufactured food item. A comparison of the age distribution of recently reported oral submucous fibrosis cases and incident cases reported in the past clearly establishes that the disease is now occurring at much younger ages. A comparison of the age specific incidence rates of mouth cancer (ICD 143-5) during 1983-87 and 1995 in the city of Ahmedabad shows that the incidence has significantly increased in the younger population (< 50 years). Since tongue cancer (ICD 141) does not show a similar increase, it is concluded that the increase in mouth cancer incidence is real. Urgent public health measures are required to curb this new but avoidable epidemic.
