Colds May Trigger Childhood Cancers
Tiger4 writes "BBC News is reporting that the incidence of childhood cancers may be affected by the colds that child has had. From the Article: 'Scientists have found further compelling evidence infections such as colds may trigger childhood cancers. The University of Newcastle-led team looked at 3,000 childhood cancers in 0 to 14-year-olds from 1954 to 1998, the European Journal of Cancer reported. Researchers found unusual clusters of brain tumors and leukemia which were typical of infection-related disease.' As much as an 8 percent increase was observed. However, the article goes on to say that some risks go down with very early exposure to other children, 'In April, a Leukemia Research Fund study found that children introduced to nursery before the age of one were found to be at lower risk of leukemia.'"
I personally think once more research is done into this, they're going to realize that it's not the colds themselves, but, people overmedicated their children with over the counter pills with doses larger then recommended...
If a kid has to suffer cold, most likely her family's financial condition is not good, therefore cannot provide a lot of necessary nutritions to her developing body. Could this be the cause too?

Is is also possible that the same children that have a weak immune system and get more colds would also be more susceptable to cancer? So both the colds and the cancer are effects of some other, 3rd cause.
Or are the frequent colds indicative of a weak immune system, which in turn gives way to cancer later in life? I bet if the study was conducted over a broader range of illnesses, they'd find that these children suffered from all kinds of ailments.
So you have genetic structures being manipulted in pre-pubescent humans? Is there such a thing as early-onset testicular or ovarian cancer? Something like that could affect the stem cells producting reproductive cells.
If so, this could be concrete evidence of an evolutionary mechanism.
signatures are for fools with hands
It's interesting that for awhile, people were looking at genetic causes for various diseases such as cancer. Now we're back to the disease model, which turns out to also be due to genetics.
Basically anything that fiddles with your DNA is quite dangerous, be it smoking or radiation and the like. Viruses modify the DNA of millions of cells, most of which are destroyed in the process. Unfortunately a few survive, which can cause mutations that lead to cancer.
I suspect the early exposure to colds actually boosts a child's immune system. They're better able to fight off colds, so though they get more at a younger age, the ones they get later don't modify as many cells. Just a guess, of course. I doubt they'd approve a scientific study on modifying the DNA of small children.
They keep doing more studies and whaddaya know... everything causes cancer. Except those things which prevent it of course. Its enough to make a man skeptical.

interesting research, but i'm not exactly certain how useful their data are.
first off, the study only speaks to cancer rates in one very small (geographically speaking) portion of the world. the researchers themselves point out the importance of geography, so i'm not quite certain how they arrive at their conclusion that viral infections are linked. i'm not saying it's not possible, i'm just saying that it's a pretty common occurrance when running clustering algorithms to find that you're either converge to different solutions, your clusters actually split "natural" class boundaries, and so on. without seeing their cluster analysis results (and, in particular, what clustering algorithm they used), it's potentially easy to explain away their results as artefacts of the clustering algorithm.
secondly, the article doesn't really go into great detail, but i'm not really convinced that there is a statistically significant variation here (or, rather, i'm not sure what the statistical significance of the variation is). 8% isn't really a whole lot -- certainly not in my line of work. i imagine that when dealing with human beings, most things in that ballpark of 10% can be explained away by looking at the population variance. of course, i am not a doctor, i have no idea what their statistical methodology was, etc. etc. etc.
Are you serious? Everyone gets colds, including the rich and the poor. Colds are a part of life, just as much as shitting and pissing are.

It's not controversial. Most scientists believe that the only way for women to contract cervical cancer is to have HPV strains 6, 11, or 16 present. They're so sure about it that they believe cases in which HPV wasn't detected were due to an error in testing.
A friend of mine, Greg Cochran, co-authored a paper a few years ago suggesting that pathogens, not genes, should be looked at as the possible cause for many fitness-reducing conditions. His reasoning was pretty simple: evolution gets rid of genes that reduce fitness.
Along these lines, he suggests that homosexuality is best explained as a side-effect of some early childhood or pre-natal infection. The numbers simply don't work out for any genetic theory. (Such as the gay uncle who improves the fitness of his nieces and nephews.)
First : The only thing that the article mentions is statistical correlation. As always repeated *THAT* doesn't constitute proof of causality. Experimental proof of the *processus* is necessary before reaching a conclusion, otherwise it may be anything else, including causes due to external 3rd factor (some other /.ers mentionned bad medication, defective immune system or poor socio-economic level. The article itselfs mentions this may depends on genetic factors), or even pure coincidence (this study hasn't been replicated yet).
Second : There's a lot of virus that can cause cancer. They do this by inserting bogus genetic material into the cell that causes it to replicate, or that disables important anti-cancer genes at the point of insertion.
Examples of such known viruses includes Human Papilloma Virus, of which some variants (although rarer in the western world) could cause cancer of the woman genitalia (to be precise : the cervix. It's a part of the uterus) and is routinely monitored by the gynecologist.
Some of these viruses, like the Epstein Barr virus, may only manifest as "colds" or even be asymptomatic, specially in young children (Mononucleosis happens more to older children).
So, most likely, cancer isn't caused by "common cold" (influenza, RSV, or a bunch of other common viruses and bacteria), but the increased numbers may be explained because some cancer-associated viruses may have "cold"-like symptoms. (Even if the "cancer" variant are rarer in europe than some other parts of the world, as far as I know)

The Intelligent Designer works in Mysterious Ways. Who are we to question? It's all part of the Intelligent Designer's plan. Cancer is probably just the Intelligent Designer's method of solving the need for more angels in Heaven.
At least, that's my understanding from watching crazy religious people any time tragedy strikes.
Haven't you ever watched TV? The rich never shit or piss!
They're obviously wealthy enough to have someone do it for them!

I just wanted to say that this is a correct statement... I did research related to this (well actually vaccine development utilizing HPV E2 E4 proteins) a while back and the controversy of causation is almost non-existent. I can't remember the statistic, but almost ALL cervical cancer cells from patients have contained HPV genomic fragments incorporated into the cellular DNA.

Just another excuse to stay home from school.
Not to support ID, but probably as a form of negative feedback. You don't want your creations populating your planet out of control. If you've ever written predator/prey population simulations, you know what I mean.
I'm a staunch evolutionist, but "Why would God do X?" questions are not the way to fight Creationism. You are trying to claim you know what some immense superbeing would optimally do when creating a self-sustaining planetary ecosphere, and that's actually worse than the ID-ers arguments.
Haven't you ever triggered and earthquake or flood in SimCity just to see what happens? ;-)
A number of researchers over the years discovered that what was being called cancer was in fact fungal infections, and tumors were masses of fungal cells. Fungi behave the same way "cancer" does: they change the DNA of their host cells, they cause oxygen-breathing cells to become anaerobic instead, relying on fermentation for their nutrition, etc.
Antibiotocs kill the beneficial bacteria that keep fungus in check. Cancer rates started to explode after WWII, concurrent with the rise of antibiotic use. It could be that what we're seeing is actually an explosion of fungal infections, but interest in studying and testing for fungus waned as scientists became enthusiastic about studying bacteria, viruses and retroviruses.
Many people seemingly come down with cancer after experiencing an illness for which they took antibiotics. Since many doctors and parents still insist on giving antibiotics to children with colds, there "could" be a connection. Many illnesses that doctors still give antibiotics for may actually be fungal infections, and the infection remains after the course of antibiotics runs out. Sinus infections come to mind. At least 80% of sinus infections are actually fungal in nature, but the majority of doctors don't test for fungus or prescribe antifungals- they still give antibiotics instead. There are other ways to "catch" a fungus; antibiotics are only one way.
A number of children with leukemia that develop "secondary" fungal infections have gone into remission as a result of the antifungal medication they received. What if their problem was never cancer in the first place, but was a fungal infection to begin with? If you want more information about this, I HIGHLY recommend a book by Doug Kauffman called "The Germ that Causes Cancer". It has a lot more scientific documentation in it than the cheesy title would indicate.
I think a few colds causing Childhood Cancer are a small price to pay for the continual protection from Martian Invasion that the common cold provides us.
Stop intellectual property from infringing on me
"faith in science and scientists"
Science is science because its based on doubt. I also immediately went for the third conclusion. Perhaps something is depressing the immune system, while weakening you enough for the cold may lead you to another infection. Perhaps its a hormonal problem, which often affects the immune system too, that is overstimulating cell growth in that region for a prolonged period. Maybe it is the previously mentioned overmedication, or a certian type of medication even. All that theyve proven at this point is that its more than coincidental that the two are found together. Faith only leads you to erroneous conclusions.
Children with weak immune systems are susceptible to both colds and cancer?
William of Ockham would agree with me. (-:
Either way, don't feed them crap: breast-feed for as long as reasonably possible, then get them into eating their food as fresh, raw and un-tinkered-with as possible (a tactic which admittedly might not go down well amongst meat lovers).
Got time? Spend some of it coding or testing
You are mixing two things up. The maker in the ID is unspecified. The only thing assumed about her is she made life on Earth. It is quite arrogant to claim you spotted one of her mistakes as that implies you know how to design a complete ecosystem better than her. This is just what is wrong with ID, no scientific argument can falsify it (short of designing a brand new ecosystem not modelled after Earth, performing better than Earth on some objective basis.)
OTOH, Creationism's designer is already specified. He has some characteristics that doesn't allow him to do all stuff he wants to (eg. he can't possibly select random souls for eternal damnation, that wouldn't in character.) So, it is possible to attack creationism with arguments about design flaws in living beings. That would just be biological version of problem of evil.
