Descriptive epidemiological assessment of urinary bladder & kidney cancers in Greater Bombay.

For studying the descriptive epidemiology of cancers of the urinary bladder and kidney, the data reported by Bombay Cancer Registry for the most recent five years have been utilised. For studying time trends in these cancers, data of the past 30 yr have been used. In Bombay, bladder cancer is very uncommon in the first three decades of life; but after the age of 30, the incidence rates increase with age, in log-linear fashion, in both sexes. The incidence of kidney cancer is almost absent between the ages 5 to 35; but later up to the age of 70, it show a steady increase. The incidence of urinary bladder and kidney cancers are found to be associated with the marital status in both sexes. No association was observed between the incidence and educational level attained by the patients having urinary bladder and kidney cancers. An increasing trend was found in the age adjusted incidence rates of cancers of the urinary bladder and kidney in both sexes during the period 1964-1993.
