Study: Some Antioxidants Could Increase Cancer Rates
sciencehabit writes "Many people take vitamins such as A, E, and C thinking that their antioxidant properties will ward off cancer. But some clinical trials have suggested that such antioxidants, which sop up DNA-damaging molecules called free radicals, have the opposite effect and raise cancer risk in certain people. Now, in a provocative study that raises unsettling questions about the widespread use of vitamin supplements, Swedish researchers have showed that moderate doses of two widely used antioxidants spur the growth of early lung tumors in mice."
Also, cancer cells are more susceptive to oxidative damage due to their generally higher cell division rate. This is also why ionizing radiation usually damages cancer cells more than regular cells.
Most study's only find what they want/paid to find. The question now is who is correct? We are told to trust scientists that they are objective and unwilling to compromise ethic's for money. Well now what?
Since when sentences need verbs?
I did read anywhere in the article that taking vitamin E makes you die younger. This is more like the contraceptive pill argument. If you think you are susceptible to certain cancers, avoid. Otherwise, the benefits may be worth it.

we should stop putting unnatural things into our bodies that should only be enjoying god's creations
Yeah, all the great things god created, like Mycobacterium tuberculosis, Clostridium tetani, Variola virus, Poliovirus, let's put all that stuff in our bodies, not those evil vaccine things!
Antioxidents are an interesting idea. A whole industry has built up around their healthy properties. However, it transpired that the only evidence of their efficacy was adding various compounds to cells in a petri dish. There was no evidence any of this actually worked when swallowed and ingested. Some further research was done recently and could find no evidence that taking these products actually had any affect at all on reducing your chances of getting cancer.

Supplements are just one more useless thing that businesses convince people they need. The only ones that need them are businesses, to make shitloads of money.
If you have a varied and balanced diet and don't suffer from any condition that makes you need a reinforced dose of any particular nutrient, you don't need any dietary supplements.
Eat properly and exercise! It's easier, cheaper, and it works.
You do realise that was completely debunked years ago?

....word choice. Some antioxidants are good killers of cancer cells, and some aren't. Like various chemotherapies, you need to know which ones in which combinations and dosages work, and which don't, for a particular cancer.
Been there, done that, works well. This article just sounds like another pharma shill attack on supplements.
Everything today will increase your risk of getting cancer, if you tried to live life on a diet that had the least risk of cancer causing agents you would have to starve yourself. Sure maybe this study is right and taking vitamins could increase your risk of cancer but honestly if it wasn't vitamins it could be anything else. Just keep living the life you're living and don't worry about something as stupid as if you took your vitamin A today or not.

"Now, in a provocative study that raises unsettling questions about the widespread use of vitamin supplements"
I believe that should be worded, "Now *another* provocative study" After all, there's been a continuous stream of these. For whatever reason, the human body doesn't like being dosed with massive amounts of chemically reactive substances, gee, what a surprise.
You can get the same dose from eating fruit, but that has no known downsides in multiple studies. If you're worried about your health, eat your fruit and veg - like they've been saying forever,
The chirality of a molecule only speaks to its polarization - whether it scatters incident EM field with right hand or left hand polarization. Basically, your molecule can have the same formula, but be wound clockwise or counter-clockwise.
The human body absorbs chiral nutrients, but is often found to absorb left hand much better than right hand, or vice versa, depending on what the nutrient is.
Synthetic vitamins are manufactured to be monenantiomeric, meaning that they only have the useful version of the molecule.
It's slightly more sophisticated than that; chiral molecules will rotate polarised light one direction or the other, but what makes them chiral is the spatial arrangement of the chemical groups. That has significant implications for reactivity, so for example all life on Earth can only use one chirality of amino acid and not the other. (One of the wonderful effects of common descent.) The upside of the effects on reactivity that you can come up with chirally-controlled syntheses, as you say. And of course not every compound is used by the body in a way that even notices its chirality.
No kidding!!! What do you say at this point?
This is a common sleight of hand in the pharma (or general 'sickness industry') sponsored mercenary pseudo-science, when they want to "prove" that inexpensive, non-patentable substance X which is actually good for you, "causes" cancer -- they give X to mice bred specifically to develop cancers they wish to blame on X. After the coarse grained form of the "discovery" story is retold in mass media (or on Slashdot), it becomes "X causes cancer."
To see exactly how this sleight of hand works, consider substance X that improves circulation and promotes growth and vitality of blood vessels (e.g. gingko biloba, arganine, etc), which are all the effects normally good for you. But if you get a cancer, then cancer will use the improved blood supplies and stronger angiogenesis to feed itself, hence it will grow faster than if you had poor circulation and suppressed angiogenesis. That is then twisted to declare "X causes cancer." In fact the cancer was caused by the genes that were deliberately bred into this type mice.
More generally, onset of cancer turns values upside down -- what was good for you when you were healthy, becomes bad for you when you get cancer, since cancer will co-opt it for its own growth. What was bad for you (poor circulation, cellular toxins and pro-oxidants, heavy metals, chemo, etc) becomes good for you, since it may affect cancerous cells more than the non-cancerous cells.
A useful analogy illustrating the nature of this reversal of values in cancer, is to consider human society as a (super-)organism, which it is in many ways. In a peacetime, roads and other transport systems are good for the social organism. But in the case of war, the good transport systems often becomes a major downside since the enemy can use those roads to advance its troops and boost supply lines. In contrast, poor transportation in peacetime is bad for the social organism (backward nations). But it is also bad for the potential enemy during war. This can be easily observed on historical examples, such as WWII, where German blitzkrieg conquered the more developed nations, such as France, Netherlands, Poland very quickly, while it got bogged down in the backwards Balkans, with lots of mountains and few roads, and never really had control of those territories (except for the major cities, which were few in numbers). Similarly, in more recent wars, the backwards, mountainous undeveloped Afghanistan (or jungles of Vietnam) is practically impossible to conquer, while the more developed Iraq was overrun in weeks.
Hence, the above style of mercenary "science" using cancer mice to "prove" alleged carcinogenicity of wholesome Vitamin C or E is analogous to mislabeling transport systems and other infrastructure as a national weakness, and advocating going back to stone age, by demonstrating how much quicker the nation can be conquered if their infrastructure is good.
It is also similar to policies which mislabel personal liberty and privacy as harmful and deadly, by showing how terrorists (or drug dealers, crazies, etc) can take advantage of those liberties and privacy to cause harm. These are all the same kind of scams as the above "study" scaring people away from the vitamins C and E. All of such scare campaigns are often promoted by the very same people from the same crony front groups/NGOs, as result of natural synergies of interests -- a need to condition and herd the sheep with common scare tactics.
I actually find these kinds of "studies" quite useful, since they help me identify what is good for me -- it is always the stuff that the sickness industry is trying to scare me away from (e.g. fat, meat, eggs, bacon, cholesterol, tobacco and other ancient medicinal/entheogenic plants, etc). Further, as a rule the greater the efforts and lengths they go to with their scare mongering about X, the better X must be for me (i.e. worst for their profits). The most useful one for my health was when it dawned on me to invert "make sure have the regular medical checku

Heh, reminds me of an oldie, but a goodie -
All things dull and ugly,
All creatures short and squat,
All things rude and nasty,
The Lord God made the lot;
Each little snake that poisons,
Each little wasp that stings,
He made their brutish venom,
He made their horrid wings.
All things sick and cancerous,
All evil great and small,
All things foul and dangerous,
The Lord God made them all.
Each nasty little hornet,
Each beastly little squid.
Who made the spikey urchin?
Who made the sharks? He did.
All things scabbed and ulcerous,
All pox both great and small.
Putrid, foul and gangrenous,
The Lord God made them all.

I agree with your point, but oxidane is the preferred name for dihydrogen monoxide [http://www.iupac.org/fileadmin/user_upload/publications/recommendations/nomenclature-of-organic-chemistry/Chapter2-Sec20-24.pdf]. Also, dihydrogen is just one word and doesn't need a hyphen.

I take it God didn't create punctuation.
Just in case you're not simply a troll... you're a hypocrite as well as ignorant. Do you eat any modern foods - bread, milk, cereal, etc? They're all made with "unnatural" things, like preservatives and have gone through "unnatural" processes in factories.
Truth is, EVERYTHING is natural. What can possibly exist which isn't made from naturally occurring materials? Chemicals exist because your God created them. We are MADE OUT OF chemicals. All science does is examine what is already there, and find solutions to problems using - again - stuff which is already there. Stuff "God made".
God made cyanide too, and bacteria and viruses. You can't have it both ways. That house you live in, to protect you from God's diseases and beasts that would kill you, and God's extreme weather that would also kill you, was made thanks to science.
If you believe God doesn't like science, then that's your right. But don't bitch about it on the internet in your comfortable chair. Go live in a cave, like God intended, and stop bothering us normal, sensible people. Remember to take a few sharp stones, if you can find some. If you get into trouble, just pray and all will be fine, I'm sure.
they are called whole foods for a reason. The sugar in fruit is just as bad as any sugar, unless you counter it with the fiber from the fruit. Table salt is made of two compounds, either of which is deadly on its own. Coca leaves cause very few health problems, even with chronic use. We informed potheads also get very grumpy when a study blasts marijuana using results obtained by dosing subjects with huge amounts of synthetic THC.
Hippies and "natural foods" folks are easy to mock, but they have a point -- at least for the moment, it's foolish to assume we understand all the nutritional benefits of every food and how all its components interact with each other and our bodies. That doesn't mean all synthesized compounds are dangerous (e.g: salicylic acid, aspirin, does okay and is more effective than its natural source, willow bark). But just introducing random beneficial compounds into our body in isolation is like sticking a pan of flour in the oven and being surprised when it doesn't bake into a loaf of bread.
