What is Molecular Epidemiology?

Molecular cancer epidemiology is a science that:

  • seeks to identify human cancer risk and carcinogenic mechanisms to improve cancer prevention strategies
  • is multi-disciplinary and translational, going from the bench to the field and back
  • uses biomarkers and state-of-art technologies to gain mechanistic information from epidemiological studies

Some examples of molecular epidemiology studies include:

  • genetic susceptibility for the causes and prognosis of cancer
  • gene-environment interactions in cancer risk (e.g., p53 mutations, estrogen receptor expression, etc.)
  • urinary biomarkers for tobacco carcinogens, estrogen metabolites, mutagens, etc.
  • DNA damage in blood as a result of environmental exposures from lifestyle factors, foods, chemicals, etc.
