Aim
To study differences between various methods of estimating cancer risk in individuals.
Method
Information was obtained from Bombay cancer registry. Life time risk was calculated using the life table method, taking competing cause of death into account and using well recognised methods such as the cumulative rate and risk.
Data Source
(a) Lung Cancer data from the urban population based cancer registry of Greater Mumbai for the year 2001 has been used.
(b) Population data for the years 2001 from district census handbook.
(c) All cause mortality data from Bombay Municipal Corporation has been obtained.
Results
The lifetime risk of developing cancer was estimated to be 9.8 % for males and 10.1% for females. In males, the risk estimated was considerably high when the cumulative risk method was used.
Conclusion
The life table method is convenient for estimating the probability that a person will develop cancer during a defined period or during his or her life time. The other methods over estimates the risk of the disease under study especially in the older population.
