Artificial sweeteners– do they bear a carcinogenic risk?

Abstract
Artificial sweeteners are added to a wide variety of food, drinks, drugs and
hygiene products.
Since their introduction, the mass media have reported about potential
cancer risks,
which has contributed to undermine the public’s sense of security.
It can be assumed that every citizen of Western countries uses artificial
sweeteners, knowingly or not.
A cancer-inducing activity of one of these substances would mean a health
risk to an entire population.
We performed several PubMed searches of the National Library of
Medicine for articles in English about artificial sweeteners.
These articles included ‘first generation’ sweeteners such as saccharin,
cyclamate and aspartame, as well as ‘new generation’ sweeteners such as
acesulfame-K, sucralose, alitame and neotame.
Epidemiological studies in humans did not find the bladder cancer-inducing
effects of saccharin and cyclamate that had been reported from animal
studies in rats.
Despite some rather unscientific assumptions,
there is no evidence that aspartame is carcinogenic.
Case-control studies showed an elevated relative risk of 1.3 for heavy
artificial sweetener use (no specific substances specified) of >1.7 g/day.
For new generation sweeteners, it is too early to establish any
epidemiological evidence about possible carcinogenic risks.
As many artificial sweeteners are combined in today’s products,
the carcinogenic risk of a single substance is difficult to assess.
However, according to the current literature,
the possible risk of artificial sweeteners to induce cancer seems to be
negligible.

"Aspartame entered the market in 1981 as the third artificial sweetener,
and was free of any suspicions regarding carcinogenicity."
[ In fact, at that time,the FDAs own expert Board of Inquiry voted against
approval of aspartame, due to unresolved concerns about its carcinogenicity,
and was arbitrarily overruled by the brand new Commissioner, Arthur Hull
Hayes, appointed by the new President Reagan:

Both reviews are five pages long.
Is the 2004 review (in English) substantially different from the 2001 review
(in German)?
The most recent reference in the 2004 study is in 2001,
but refers to a January 1973 aspartame industry study,
which was not published in a peer-reviewed mainstream scientific journal:
32. Study E33-34 in Master file 134 on aspartame.
On file at the FDA Hearing Clerk's Office 2001.
At the end of this post I give the full text of the 3-page California OEHHA
aspartame critique 2004.03.12: Carcinogenicity Data Summary: Aspartame,
which is critical of the flawed aspartame industry study E33-34 (Searle
Laboratories, 1973), which stated:
"There is, however, some carcinogenicity concern over observations of brain
tumors in aspartame-treated rats.
Reliable animal studies have not been conducted despite the widespread human
exposure to this artificial sweetener.
Epidemiologic data provide inadequate information on which to judge
carcinogenicity....
Further epidemiologic and toxicologic studies are needed on the
carcinogenicity of this chemical.
No large epidemiological studies of carcinogenicity have been conducted."
Obviously, Weihrauch and Diehl are less than candid in their reference to
this biased study, and this in turn indicates their probable bias.
Remarkably, Weihrauch and Diehl do not mention stevia at all, although it
has been a dominant sweetener in Japan for decades,
while its safety is supported by 25 studies in the last twelve years:

Claim: "DNA repair assays for the evaluation of genotoxicity of substances
did not show any DNA-damaging properties for aspartame, cyclamate,
saccharin, acesulfame-K or sucralose [30]. "
Note the striking experimental evidence to the contrary for all of these
sweeteners, except acesulfame-K and stevia, reported by Yu F Sasaki’s expert
team in Japan in 2002 August, summarized below, near the end of this post.
It is significant that they did not discuss or reference the seminal
experimental study by C Trocho and M Alameny in 1998 June that demonstrated
that aspartame at the low dose of 10 mg/kg for 10 days causes formaldehyde
adducts to DNA, RNA, and proteins in the cells of rats:

So far, no aspartame toxicity studies, epidemological or experimental, have
controlled for other major simultaneous, ubiquitous sources of methanol and
formaldehyde in humans. However, the expert review of methanol
(formaldehyde, formic acid) toxicity by M Bouchard et al in 2001 makes it
clear that very little has been established about the nature and toxicity of
the substantial durable, cululative products of methanol in human tissues:
