In response:
"Proofs:
1) People died of cancer before any cancer treatment existed."
   Of primary importance is the correction of any habit inimical
   to health. Without this change in "lifestyle" people will
   continue to die of cancer regardless of treatment.

"2) Clinical studies show that statistically, treatments *reduce*
mortality, i.e. people who have cancer treatment are less likely to
die than people who don't."
   It is fallacy to believe that because someone didn't actually
   die, the treatment saved him. What if the patient 'lived' in spite
   of the treatment. There is no way of knowing if a person  would
   have died other than actual death. It is a statistical supposition
   the person would have died, and should be viewed as such.

"3) Carcinogenicity of chemicals are routinely tested on mice. These
mice die, although their cancer is not treated by drugs or surgery."
   It is no wonder that carcinogenic material would cause cancer
   in laboratory animals. To artificially violate the defenses of the
   body with filthy foreign substances beyond its capacity, then
   expect health to suddenly be restored is wishful thinking.

As someone once said "How can something that makes a well man sick,
make a sick man well?"
The idea behind this is that if a substance is not utilizable by the
cells for nutriment then it must be expelled. If it must be expelled
it can be safely classified as a poison. If a substance is a poison
to a healthy person, it is also poison to the 'sick' person.
There must be limits to the amount of abuse the body can take.
A body debilitated and weakened by bad habits that develops cancer
needs a change of lifestyle not more poisons and enervating
'treatments'.
The giving of substances non-utilizable to the cells in the normal
process of life, can only make matters worse. I believe it is safe to
say that in the Kushi case as well as all the others the treatment
killed the patient. In these cases the the treatment was given and
the patient died. The conclusion is self evident.
I do however agree with the following excellent advise ...

"1) Do NOT tell him/her to avoid treatments. Even surgery alone can
be life-saving. At any rate, never impose your point of view on the
patient,otherwise you would be held responsible if the patient dies.

2) Provide him/her as much moral support as possible. This is the
only thing everyone agrees that it's useful.

3) Discuss diets and/or alternative treatments only if you think
he/she might be receptive. Otherwise, he/she won't listen, will think
you are crazy or will be irritated. At any rate, do not blame the
patient ("you have lived incorrectly, now this is your punishment"),
this is not constructive and irritating for someone who is facing
death."
