What is not a carcinogen?
410797
500 years ago, Paracelsus, an early chemist, doctor and alchemist (which, at the time, was still a going concern) wrote (in German):\n\n"Alle Ding' sind Gift und nichts ohn' Gift; allein die Dosis macht, das ein Ding kein Gift ist."\n\nThis means:\n"All things are poison and nothing (is) without poison; only the dose makes that a thing is no poison." \n\nWhatever science may think of some of his stranger pursuits, the wisdom of this statement is undisputable.  Every substance will kill you if you ingest enough of it, even water.  (And, no, I'm not talking about drowning.)\n\nAny substance that can damage a DNA molecule can be a carcinogen.  This includes nearly every molecule, again, including water.  The only completely non-carcinogenic substances I can think of would be the noble gasses (helium, neon, etc.)  They are chemically inert and do not readily react with much of anything.  Even that's not completely safe because radon is a radioactive noble gas (so easily a carcinogen) and some of the others probably have radioactive isotopes.\n\nIt's worth noting that despite the earlier "answer", natural things are full of carcinogens.  Plants are filled with pesticides of their own creation.  Why not?  Plants don't like being eaten any more than you would.  Natural pesticides are simply the result of their evolution.  These pesticides are designed to, yes, KILL animals.  That includes you.  Of course, we don't eat the ones that have enough of those chemicals to kill us in the short term, and only a few of our foods (such as, I'm told, Okra, which supposedly has the highest levels of natural pesticides of any food regularly eaten by humans) have enough pesticides to be really worth avoiding.  Nonetheless, the chemicals aren't intended to be good for you and some of them do indeed contribute to cancer.\n\nFunny irony:  Plants grown "naturally" or "organically" have more natural pesticides than those grown by supposedly bad, unnatural modern techniques.  "Organically" grown plants are exposed to more insects, and the plants respond by pumping up excess carcinogens and other poisons into their tissues.  Plants protected by artificial, external pesticides have less trouble with pests, so don't produce as many poisons.  Guess what, you cannot wash off internal, natural pesticides like you can the artificial ones humans add.\n\nAgain, the dosage of these natural pesticides is still usually too small for concern.  Still, if you want my advice, avoid overpriced "organic" foods.\n\nRemember the Alar scare from quite a few years back?  Everyone worried about the Alar on apples being carcinogenic.  Everyone ignoring the plain fact that the supposedly dangerous aspect of Alar was that it broke down into unsymmetrical dimethylhydrazine (UDMH).  UDMH is found in much higher doses in supermarket mushrooms than found on treated apples.  The treated apples were banned, the mushrooms remain on the shelves to this day, protected by the strange and irrational sense of safety the phrase "all natural" gives to people.\n\nMind you, I'm not saying the mushrooms are dangerous.  They aren't.  Neither were the treated apples.  The dose makes the poison and neither has enough to worry about.  The news media likes scare stories, so it prints them without much regard for the facts of the issues.

Liver and kidney problems. No, it is not cancer.

There is all sorts of conflicting data on this one, but here are a few sites with some info on studies:\n\nhttp://news.bbc.co.uk/1/hi/health/141891.stm\nhttp://www.webmd.com/content/article/23/1728_57309\nhttp://www.cancer.org/docroot/CRI/content/CRI_2_4_2X_What_are_the_risk_factors_for_lung_cancer_26.asp\n\nI tend to lean toward the yes side, I just can't picture smoking being ok for the lungs, and the smoke does have carcinogens in it.

Yeah, because gas has lead and cadmium which is carcinogenic and causes the mutation of cells when incorporated into the body then that's how you get cancer.

Asbestos is not technically an element (as in not on the periodic chart), but is a known cancer causing agent and is no longer in use - at least in the U.S.

Cancer is not one disease, but many different diseases with different causes. For that reason, one breakthrough "cure for cancer" is probably not likely to come along.

There are more than 4,000 ingredients in a cigarette other than tobacco. Common additives include yeast, wine, caffeine, beeswax and chocolate. Here are some other ingredients: \n\nAmmonia: Household cleaner\nAngelica root extract: Known to cause cancer in animals\nArsenic: Used in rat poisons\nBenzene: Used in making dyes, synthetic rubber\nButane: Gas; used in lighter fluid\nCarbon monoxide: Poisonous gas\nCadmium: Used in batteries\nCyanide: Deadly poison\nDDT: A banned insecticide\nEthyl Furoate: Causes liver damage in animals\nLead: Poisonous in high doses\nFormaldehiyde: Used to preserve dead specimens\nMethoprene: Insecticide\nMegastigmatrienone: Chemical naturally found in grapefruit juice\nMaltitol: Sweetener for diabetics\nNapthalene: Ingredient in mothballs\nMethyl isocyanate: Its accidental release killed 2000 people in Bhopal, India in 1984\nPolonium: Cancer-causing radioactive element

glucosamine or glucosaminoglicans are  just  natural compunds \nand by the way as this point is  so missunderstod amoung most of the population not all chemicals  are  carcinogenic  not even the  very harmful ones only few of them  are very few carcinogenic materials should have very specific  characteristics to be  really carcinogenic\nso no possible  way  the sevenseas product is  carcinogenic

Not always gives cancer, but it has metals in it, but there are alternates such as Bert's Bee's type deoterent.\nIt does'nt contain any metals although it may be a little more expensive.\nI dont know what kind of cancer it could cause, but remember, it goes in your bloodstream, so it could cause any kind.\nIt's best to avoid all metals in your body.\nNo idea what the chances are.

To fix the second response, I must just say that an individual can have any type of mutation; it does not have to be cancer. A carcinogen (cancer-causing substance) is a type of mutagen (a substance that causes mutations in individuals), and there are many chemicals that are not carcinogenic, but are indeed mutagens (exempli gratia, certain base-manipulating mutagens).\n      Now that this is cleared up, I will say that changes in genetic makeup in an individual is a mutation, and in a population, is evolution.\n      In truth, your question is one that can be taught over the period of months. Basically (and I know that my fellow biologists will be mad at me for trying to simplify such a complex subject), over time, the usage and presence of of introns and exons changes. Introns are "intervening" parts of the gene (and are not expressed), and the "exons" are the expressed portions. Introns are the "junk" in an individual's genes, yet over time, a population may realize that this "junk" can actually be useful in adapting to the organism's environment. This results in evolution. I do advise that you read more about the intron-exon system. Evolution is, put simply, changes in an organism's genome, OVER TIME, caused by the reproduction of the fittest of the species.

Everything around us is a chemical. That is all foods, all fibers, natural materials in the environment as well as the man made materials.

i would say yes, we just don't call it cancer.  like then a plant has a fungus or a moiser problem.

Because the gastrointestinal (GI) tract encompasses many different organs, GI cancer could include (but not limited to) the following types of cancer:  esophageal, small intestinal, colorectal, hepatic (liver), pancreatic and gastric (stomach) cancers, as well as gastrointestinal endocrine cancers.  There are numerous risk factors for many different kinds of cancer, such as tobacco, alcohol, diet, sunlight, radiation, and hormone replacement therapy.  Most of these can be avoided.  There are also inherited risk factors that cannot be avoided.\n\nSo, what I'm trying to say is that your question is difficult to answer.
