hypothesis is that particular unnamed parasites induce almost all 
cancers, perhaps by excreting metabolites.  In developed countries, 
parasites are very uncommon.  The approaches mentioned could not 
confirm the presence of parasites in the liver or elsewhere, nor 
could they identify local collections of isopropyl alcohol, freon, and the 
bizzare list of other compounds mentioned by Dr. Clark.  So it seems 
unlikely that her essential hypothesized mechanism(s) for causing 
cancer (parasitism) and for curing cancers (killing parasites), are correct.

It is not rare for scientists to make wrong guesses or hypotheses, 
because eliminating wrong guesses, is how scientists approach more correct 
or predictive theories.  Here, there is the proverbial "grain of truth"; 
correlations and animal models show that some viruses like Hepatitis,
and probably some other infectious agents, can help induce cancers;  
but these are not the "parasites" described by Dr. Clark.  Again, 
eukaryotic parasites are very rare in the US and Canada, and cannot 
possibly cause the list of diseases mentoined by Dr. Clark; these 
diseases and chemicals cannot be measured easily, certainly not by 
someone with undergraduate physics many years ago; the most advanced 
recording devices and labels would not begin to quantify this list of 
chemicals in an intact body.

I recommend skepticism.  It is unfortunate that this is apparently a 
published book; it is certainly not peer-reviewed.  Both parasitologists 
and oncologists will recognize its publication "at best", as an 
error.  Unfortunately, this type of error can be hard to correct, because
in areas outside of one's specialty, many people tend to regard alternative
explanations as equally likely.  Many things are not known about 
parasites and cancer.  However, there are enough obvious errors in the interview 
to recommend extreme caution!  Most money spent on cancer through 
accepted institutions is also wasted, but at least most of the players are 
acting on the best available data and hypotheses.
