title: [Time trends, estimates and projects for breast cancer incidence and mortality in China].
abstract: OBJECTIVE
  Using comprehensive available data on women breast cancer in China, to describe the mortality trends from late 1970s, estimate and project the profile in 2000 and 2005, and to aim to provide a reference for clinic, basic research and prevention and control strategy making for breast cancer in China.
  
  
  METHODS
  Using Joinpoint model, the mortality trends were analyzed on the basis of routine surveillance data. Combining with the data from the second national mortality survey and several cancer registries, using the log-linear model (based on Poisson distribution), the breast cancer profile in 2000 and 2005 were estimated and projected.
  
  
  RESULTS
  Although there was a slight decline in mortality between early 1970s and 1990s, the age-specific mortality rates among young and middle age women increased dramatically which followed a continuing increase trend on both rates and absolute numbers, in both urban and rural areas in recent 15 years. Compared with 2000, there are 470 thousands more new breast cancer cases and 130 thousands more deaths from breast cancer in 2005.
  
  
  CONCLUSIONS
  Due to the double effects of both increasing risk factors and population growth and ageing, breast cancer will be one of the most extensively increasing cancers in Chinese women. The prevention and control of breast cancer will be of great emphasis for future cancer control strategy in China.
