The largest cancer registry in Canada covers approximately 38% of the total population.

• A. True
• B. False
• C. Not specified
• D. Unknown

Answer: (A)

In cancer surveillance, coverage refers to what portion of the population is represented by the registry’s data. Canada’s national perspective comes from the Canadian Cancer Registry, which gathers information from provincial and territorial cancer registries. It doesn’t include every region at all times, so the national dataset captures only a subset of the population. The figure commonly cited for the Canadian Cancer Registry’s population coverage is about 38%, so the statement is true. This means national cancer statistics are based on data covering roughly two-fifths of Canadians, with extrapolation or modeling used to estimate incidence in the rest of the population.
