ABSTRACT: Trends in breast cancer incidence in Hong Kong between
1973 and 1999: an age-period-cohort analysis
Hong Kong has the highest breast cancer incidence in Asia and
studying secular changes in its rates may lead to hypotheses
regarding disease aetiology and also predictions of future trends
We examined statistics from the Hong Kong Cancer Registry
based on 26,566 cases of invasive breast cancer from 1973 to 1999.
The trends in breast cancer incidence were studied using log-linear
We further analysed the independent effects
of chronological age, time period and birth cohort on incidence
trends using age-period-cohort modelling.
The average annual per
cent change of the age-standardised incidence was 3.6% during
1973-1999. Age-period-cohort modelling indicated the incidence
development was predominantly a cohort effect, where the rise in
relative risk was seemingly linear in successive birth cohorts,
showing a 2-3-fold difference when comparing women born in the 1960's
with those born around 1900.
Our results suggest that direct and
indirect consequences of westernisation may have been responsible
for most of the observed increase in breast cancer incidence.
China moves towards a more westernised way of life, we can expect
an emerging epidemic of breast cancer as Hong Kong's experience
