title: An Assessment of Cancer Incidence Patterns in Parsi and Non Parsi Populations, Greater Mumbai.
abstract: The Mumbai Cancer Registry has been in operation since 1964 and reliable morbidity and mortality data on cancer have been obtained for the first time in India, from a precisely outlined population. An attempt has been made to examine the differences noticed in the site-specific cancer risk, between two groups of people living in this area-the Parsi and non Parsi population of Mumbai. For this study, data has been utilized, collected by Mumbai Cancer Registry for the latest five years. For comparison between Parsi and non Parsi populations, crude and age-adjusted rates have been used. The overall age-adjusted rates for the Parsi's were found to be lower than those for the non Parsi populations and more noticeably their site-specific risks seem to differ radically from the non Parsi pattern. Cancers of the buccal cavity, pharynx, larynx, oesophagus and cervix uteri which are frequently seen in the non Parsi population, are less commonly observed in the Parsi community. On the other hand the Parsi rates are higher at site such as the female breast, endometrium, lymphomas and leukaemias. The observed site-specific contrast are believed to be due to differences present in the habits, customs and economic status of the two groups.
