Trends in the prostate cancer incidence in India.

Trends in prostate cancer in five population-based cancer Registries (Mumbai, Chennai, Bangalore, Delhi & Bhopal) in India were studied over a period of two decades using a model that fitting the data as the logarithm of Y=ABx which represents a Linear Regression model. This approach showed increasing trends in the age adjusted incidence rates throughout the entire period of observation for most of the registries, especially in Chennai and Bhopal and to the least extent in Mumbai. Particularly in Asia we face a future major increase in the rates of prostate cancer. Collaborative action now is a high priority to allow the preparations necessary for effective control of prostate cancer.
