The Australian figures are around 434,000 people are treated for one
or more non-melanoma skin cancers. In 2007, 448 people died of the
disease. Regular skin cancer vary rarely kills.
Melanoma is a skin cancer, but it is usually referred to as melanoma.
In Australia
more than 10,300 people per year are treated for melanoma, with 1279
people dying in 2007.
It's not all that high a death rate as cancers go, but a lot higher
than the death rate for basal cell skin cancer which is much more
common. One of my acquaintances died of a melanoma in her forties,
which was a tragedy, but that doesn't vitiate my point either.

US figures for lung cancer are 62.5 per 100,000, breast cancer 62 per
100,000 (actually 124 per 100,000 women) and colon cancer is 47.5 per
100,000.
Most colon cancer and many breast cancers can be cured if detected
early, and energetic screening detects enough early cancers to more
than pay for itself. These are prime examples cancers where "area
where expensive test-for-everything medicine does pay off". It's

The US gets good figures for prostate cancer because they detect it
earlier, so they've got more prostate cancer under surveillance at any
one time. It's rarely worth doing anything about it so it is a cheap
win for expensive test-for-everything medicine. Our oncology professor
friend doesn't actually think that it is worth doing PSA tests for
prostate cancer - and once declared on TV in Australia that he'd sue
if anybody measured his PSA levels, because it wasn't worth acting on
a positive result.

I'm not even getting FOB testing in the Netherlands. I'll probably get
it when we move to Australia. One of my second cousins in Australia
had some kind of colon alert, and both my brothers were persuaded to
get precautionary sigmoidoscopy along with a large swathe of near
relatives, None of the relatives had a problem, so I didn't bother. My
youngest brother is a general practitioner, and very well informed on
this kind of stuff, and hasn't bothering to propagandise me on the
subject.
Colon cancer incidence in Australia does seem to be higher than it is
in the US, but Australians live longer than US residents by about
three and a half years, and cancer rates climb rapidly with age.

It's an interesting question. The patient was almost certainly under-

When I worked for EMI Central Research, they were selling X-ray body
scanners to individual physicians in the US for a couple of million
dollars a machine. The representatives comments were along the lines
that body scan images were comprehensible to everybody, including
lawyers, and thus easy to sell. It was less clear that they were
informative enough to justify subjecting the patient to 4% of a lethal
dose of X-rays. this was back in 1979.
Having more machines available than you actually need isn't actually
all that helpful. Paying for all those extra machines may be part of
what makes US medicine half-as-much again more expensive than the next
most extravagant country - Switzerland.
