Trends in the brain cancer incidence in India.

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 this purpose we applied a model that fits the data is the logarithm of Y=ABx which represents a Linear Regression model. This approach revealed an increasing trend in cancers of nervous system in both sexes throughout the entire period of observation in almost all registries. As CNS cancers are increasing, analytic epidemiological studies should be planned in a near future on a priority basis to understand the etiology of these cancers in depth.
