Captures address at time of diagnosis May not be able to account for people who
moved away from the area and then
were diagnosed and died prior to 1996
Limited information on occupation and risk

Works with individuals or communities to:
Explore their cancer concern Provide health education on cancer and lifestyle
Provide epidemiological information
Most identified cancer excesses are due to

How many people are diagnosed each year (incidence) Number of people living with cancer (prevalence) Number of people who die from cancer (mortality) Are there significant differences among certain groups

The time between exposure and clinical recognition – varies by cancer May be 10 years, 20 years, or more
Environmental Contaminant
Health effects depend on several factors:
