Trends in cancers of the central nervous system in both sexes in five Indian population based cancer registries(Mumbai, Chennai, Bangalore, Delhi & Bhopal) were evaluated over a period of the last two decades. For thispurpose we applied a model that fits the data is the logarithm of Y=ABx which represents a Linear Regressionmodel. This approach revealed an increasing trend in cancers of nervous system in both sexes throughout theentire period of observation in almost all registries. As CNS cancers are increasing, analytic epidemiologicalstudies should be planned in a near future on a priority basis to understand the etiology of these cancers indepth.
