In the Hanoi Cancer Registry, the age-standardised rate of breast cancer in women rose from 15.2 per 100,000 in 1991 to 40.6 in 2020, more than doubling over three decades.
The authors analysed 28,298 breast cancers in women registered by the Hanoi Cancer Registry from 1991 to 2020, using joinpoint regression for the average annual percent change and an age-period-cohort analysis. The registry, set up in 1987 following International Agency for Research on Cancer guidelines, is described by the authors as the first population-based cancer registry in Vietnam; it collects cases from 46 public and private hospitals in Hanoi and cross-checks new cases against health insurance identifiers.
The age-standardised rate was 15.2 per 100,000 in 1991 to 1995 and 40.6 in 2016 to 2020, with the highest number of cases in women aged 50 to 59.
Viet Nam's first population-based registry, as its authors describe it, shows breast cancer becoming much commoner in the capital, which is the background to the 2026 national plan's targets for breast screening in women aged 40 to 70.
