Let's check.
If an American and a Canadian both discovered that they had cancer, would the odds be better that the American would rush off to Canada, or that the Canadian would hurry to America.
So much for your argument.
My mother tried that argument (not specific to cancer, why narrow it down to that?). Funny thing, later in the same conversation she admitted that she (like many Americans living on fixed incomes) buy their prescription drugs from Canada
I narrowed it down to cancer because there is ample evidence that nowhere else on earth has the survival rate for cancers that the United States has.
I found mixed results when I tried to find same for the various forms of heart disease.
As you have used and anecdotal, let me throw in one:
"Holmes (see video below) was diagnosed with brain cancer, with her vision deteriorating rapidly, but was placed on the treatment waiting lists common to health care in socialist countries. While the average wait time for many procedures can run 18 months or more, Holmes actually made out pretty good by only having to wait 6 months for surgery for her brain tumor.
Rather than wait like a good little subject, she came to the States and got the health care she needed within three weeks. You know, the United States health care system liberals claim is so broken it must be replaced with a government system
you know, kinda like the one in Canada."

Has mom seen this:
"If you think all drugs from Canada are cheaper than U.S. drugs, think again. In the United States, generic drugs--roughly half of all prescriptions--are often cheaper than both Canadian brand-name drugs and Canadian generic drugs, according to a study by the Food and Drug Administration."
Or this:
"While some foreign drug manufacturers submit their products to FDA for approval, the imported drugs arriving through the mail, through private express couriers, or by passengers arriving at ports of entry are often unapproved drugs that may not be subject to any reliable regulatory oversight. FDA cannot assure the safety of drugs purchased from such sources."
Study: U.S. Generic Drugs Cost Less Than Canadian Drugs
Also, there was in interesting article in City Journal on the subject:
"He tells me stories of other people whom his British Columbiabased company, Timely Medical Alternatives, has helpedpeople like the elderly woman who needed vascular surgery for a major artery in her abdomen and was promised prompt care by one of the most senior bureaucrats in the government, who never called back. Her doctor told her shes going to die, Baker remembers. So Timely got her surgery in a couple of days, in Washington State. Then there was the eight-year-old badly in need of a procedure to help correct her deafness. After watching her surgery get bumped three times, her parents called Timely.

Very, very best wishes to you mom.
