The challenge of population based cancer registration in developing countries is enormous. In India, the first Population Based Cancer Registry named "Bombay Cancer Registry" was established by the Indian Cancer Society in Mumbai (formerly Bombay) in 1963, covering the population of the Mumbai Agglomeration. Up to now this registry has collected epidemiological information on more than 200,000 cancer incidence cases and 100,000 cancer deaths. At present this registry covers an area of 603.00 sq.kms having a population of 12 million. Here, an attempt has been made to analyse and interpret cancer incidence and mortality data for women, registered in Mumbai during 1993-97.
