For liver cancer it's about 15% higher in Canada for all SES, 10% higher for cervical cancers - and for all childhood cancers it's 5-10% higher in Canada depending on SES.
For prostate cancer specifically, that's likely due to higher screening rate guidelines in the US leading to earlier detection, not lower mortality. Prostate cancer comes up a lot because it's often used as a stalking horse, and it's generally a disease of the elderly. [1]
Specifically it came up in re: Guiliani and the UK:
> For one thing, according to the American Cancer Society, many more men are screened for prostate cancer in the U.S. than in Britain. This leads to more cases being diagnosed. And many who have prostate cancer live for years, without treatment, whether they are diagnosed or not. Thus, a higher number of diagnoses leads to a higher official survival rate. But this tells us nothing about the quality of treatment available to those who have the disease. A spokesman for the ACS told us that comparing rates in the two countries is “misleading.”
There have been evaluations of this between the US and Canada [2]
> US and Canadian differences in screening due to guidelines can potentially explain cross-country differences in breast cancer mortality and affect interpretation of international comparisons of cancer statistics.
The outcomes really are very comparable in the two systems, despite them trading top spots in different categories.
