Default Is it true about non-stick(cephalon) pans causing cancer?

I've been hearing from people to just use stainless steel and stay from
those non-stick pans. Or is this just an urban legend?

Mol Cell Biochem. 2005 Nov;279(1-2):17-23.
Effect of stainless steel manual metal arc welding fume on free
radical production, DNA damage, and apoptosis induction.
Antonini JM, Leonard SS, Roberts JR, Solano-Lopez C,
Young SH, Shi X, Taylor MD.
Health Effects Laboratory Division, National Institute for
Occupational Safety and Health, Morgantown,
West Virginia, USA.

Questions exist concerning the potential carcinogenic effects
after welding fume exposure. Welding processes that use
stainless steel (SS) materials can produce fumes that may
contain metals (e.g., Cr, Ni) known to be carcinogenic to
humans. The objective was to determine the effect of in vitro
and in vivo welding fume treatment on free radical generation,
DNA damage, cytotoxicity and apoptosis induction, all
factors possibly involved with the pathogenesis of lung
cancer. SS welding fume was collected during manual
metal arc welding (MMA). Elemental analysis indicated
that the MMA-SS sample was highly soluble in water,
and a majority (87%) of the soluble metal was Cr. Using
electron spin resonance (ESR), the SS welding fume had
the ability to produce the biologically reactive hydroxyl
radical ((*)OH), likely as a result of the reduction of
Cr(VI) to Cr(V). In vitro treatment with the MMA-SS
sample caused a concentration-dependent increase in
DNA damage and lung macrophage death. In addition,
a time-dependent increase in the number of apoptotic
cells in lung tissue was observed after in vivo treatment
with the welding fume. In summary, a soluble MMA-SS
welding fume was found to generate reactive oxygen
species and cause DNA damage, lung macrophage
cytotoxicity and in vivo lung cell apoptosis. These
responses have been shown to be involved in various
toxicological and carcinogenic processes. The effects
observed appear to be related to the soluble component
of the MMA-SS sample that is predominately Cr. A
more comprehensive in vivo animal study is ongoing in
the laboratory that is continuing these experiments to try
to elucidate the potential mechanisms that may be
involved with welding fume-induced lung disease.

Stainless steel cookware as a significant source of nickel,
chromium, and iron.
Kuligowski J, Halperin KM.
Division of Science, Engineering and Technology,
The Pennsylvania State University at Erie, 16563.

Stainless steels are widely used materials in food preparation
and in home and commercial cookware. Stainless is readily
attacked by organic acids, particularly at cooking temperatures;
hence iron, chromium, and nickel should be released from
the material into the food. Nickel is implicated in numerous
health problems, notably allergic contact dermatitis. Conversely,
chromium and iron are essential nutrients for which stainless
could be a useful source. Home cookware was examined
by atomic absorption spectroscopy: seven different stainless
utensils as well as cast iron, mild steel, aluminum and enamelled
steel. The materials were exposed to mildly acidic conditions
at boiling temperature. Nickel was a major corrosion product
from stainless steel utensils; chromium and iron were also
detected. It is recommended that nickel-sensitive patients
switch to a material other than stainless, and that the
stainless steel cookware industry seriously consider switching
to a non-nickel formulation.

breathe - breathe - breathe -

Well, after I finish my char-grilled steak, my fried alkoid-filled organic
potatoes, and have my cigar and processed beer out on the deck which is a
half mile from the upwind freeway in the prevailing winds:
and after I strip and paint my lawn chairs with methyl chloride and paint
it with the really good naptha and xylol laquer, and after I power-clean my
gutters with the new bleach mix to get all that asbestos and rubber and oil
and carbon fume residue from the traffic off them,
and then drink a cup of coffee to speed me up so I can polish the
furniture and put new scents in the air fresheners,
I'll think about that loss of nickel in my steel pans being a source of
cancer-causing agents - but not too much, lest I increase my chances of
disease more from worrying about the metal than the residue from the metal
itself would give me.

I do believe that acids will leech out nickel - how much? Can't say -
depends on temp and strength and kind of acid.

You can't be too careful these days. Now popcorn has been added to the
unsafe list - leaving only 8 foods left on the famed "not found to enhance
carcinogenic action" list.

So basically - unless you are under ten eyars old, you're screwed already.

Eat, drink, and make merry

FWIW -favorite pot materials -

Aluminum - alhzheimers, etc.
Stainless -nickel carcinogens
Teflon - long -named chemical carcinogens
Iron - liver damage in adult males
Wood- carcinogens, alkoids, and tannins
Silver - arthritis from polishing, who knows what in the polish.
Titanium - unforgiving overpriced toxic metal in its own right
Lead - worked for the Romans, didn't it?
Pottery - uranium and heavy metal contamination subject to leeching
Pewter - tin, antimony, bismuth, and copper (no lead food-frade, assuming
its not from Asia)
Glass - relatively inert, except lead based
Hemp - probably least dangerous of all, relatively speaking

Plastic reheatable box - you don't even want to know...

It's a safe bet to avoid eating the utensils or food to over 900 F.

Buy Hemp Seed Oil Capsules Hemp Seed Oil+ (THC €“ CBD) ~ In addition to vitamins, minerals and essential fatty acids, hemp seed oil+ also contains a constant level of added THC and CBD for medicinal effect.

Hemp seed oil is extracted from the seeds of the hemp plant. Hemp seeds contain less than 0.3 % THC so they are not considered to be drugs and are perfectly legal. Hemp seed oil is very good for our bodies and helps us maintain immune system balance.

Hemp seed oil is packed with omega 3, OMGA 6, and omega 9 fatty acids. It also contains large amounts of healthy fats, protein, carbohydrates and a large number of vitamins and minerals including: phosphorus, calcium, potassium , magnesium, zinc, iron, copper, iodine and vitamins E, C, B1, B2, B3 and B6 .

THC and CBD are known to have a beneficial effect when used to treat many diseases and ailments, but hemp seed oil does not contain a constant level of THC and CBD. So, the Medical weed Foundation produces Hemp Seed Oil+ and added THC and CBD. This oil has a constant level of THC and CBD, and thus a beneficial medicinal effect.

Hemp seed oil+ can be used to treat insomnia, skin problems or the flu. Moreover, these hemp seed oil+, when used in combination with the medical marijuana oil, ensures for a basic layer of cannabinoids, so you dont need as much medical cannabis oil.
