The purpose of this study is to examine the time trends of incidence rates in different sites (ICD.9) of cancer. Average Annual Age-Adjusted (world population) incidence rates by site (ICD.9) is used to estimate the parameters by linear regression method. Time trends analysis of 8 years from 1988 to 1995 in Delhi for age-adjusted, truncated (35-64 years) incidence rates to world population and crude incidence rate by site (ICD.9) did not reveal statistically significant decrease or increase in the incidence.
