The linkage of the Canadian National Dose Registry to health data was recently updated for the first time in decades, and it now includes information about more than a million people. It links individual levels of radiation exposure with Statistics Canada&#8217;s national cancer and mortality data.<\/p>\n\n\n\n<p>&#8220;We know whether someone died of cancer, and what type of cancer they died from.

And this is where having large numbers becomes really important. We are able to identify enough people who have been diagnosed with rare cancers and model the risk.
