title: Risk assessment of breast cancer in Guangdong, China: a community-based survey.
abstract: OBJECTIVE
  Compared with Western countries, the incidence rates for breast cancer in China are still low. However, breast cancer appears to be hitting Chinese women at a much younger age, with a peak between 40 and 50 years. Furthermore, breast tumors of Asian women have molecular and genetic characteristics that are different from those of Caucasian women.
  
  
  METHODS
  A community-based study was designed to evaluate the relationship between lifestyles and breast cancer risk in Chinese women residing in Guangzhou. 16,314 subjects completed the questionnaire. Potential confounding factors included sociodemographic characteristics.
  
  
  RESULTS
  33 individuals reported a history of breast cancer, yielding a prevalence rate of 202.3/100000. Associations between subjects'demographic and breast cancer risk factors were assessed. Breast cancer is associated with family history of breast cancer, X-rays received, benign breast disease and hyperlipoidemia or hypercholesteremia with elevated odds ratios.
  
  
  CONCLUSIONS
  Family history of breast cancer, X-ray received benign breast disease and hyperlipoidemia or hypercholesteremia were significantly associated with risk of breast cancer and may have potential for breast cancer risk assessment.
