At the Epidemiology and Prevention Division, we conduct research in human population such as local residents, visitors for a medical examination, hospital patients, etc., using epidemiological study methods under the following objectives.

  1. Investigation of causes of cancer (establish necessary scientific basis for cancer prevention)
  2. Development of cancer prevention methods (present effective and specific cancer prevention methods based on scientific facts)

Our main themes for 1) are

  • (a) analytical epidemiologic study to explain the association between lifestyle and incidence of cancer,
  • (b) molecular epidemiologic study, from a perspective of interaction with environmental factors, to explain the relationship with individual differences in genomic sequence (genetic factors) in development of cancer,
  • (c) nutritional/biochemical epidemiologic study to explain the relationship with intake of nutrients/chemicals, from a perspective of potential prevention through supplying nutrients/chemicals

Our main themes for 2) are

  • (a) Development of cancer prevention methods through improvements of lifestyle and evaluation of their efficacy,
  • (b) Development of individualized cancer prevention methods taking in biomarkers that include genome information, and evaluation of their efficacy,
  • (c) Evaluation of efficacy of cancer prevention methods with chemical substances.
