Study Links Cell Phones and Eye Cancer

Sara Chan writes "There have been lots of claims that cell phones might cause cancer. The Sunday Times of London reports that there now seems to be real evidence to show these claims are true, at least for cancer of the eye. A study found a strong statistical link and a feasible mechanism is known: microwave radiation is absorbed by certain cells (melanocytes) in the uveal layer of the eye (which affects their growing/dividing). The study appeared in the journal Epidemiology and the abstract is available here."

    I've seen quite a few posts mentioning this "ionizing radiation" thing. Shall I assume that it's only possible to cause uncontrolled cell division (e.g. Cancer) through damaging DNA directly, and not through indirect molecular mechanisms, such as causing RNA molecules to be built improperly? Is there a biologist out there who can confirm this, since it seems to be a common complaint about this article.

    Nope, you don't have to damage DNA to cause uncontrollable mitosis. Increased production of growth factors and/or signal transduction elements can cause neoplasias as well (look what happens in the case of goiter, for example) While a neoplasia might not necessarily be cancerous, I'd imagine it would be rather problematic to have even a benign tumor in your eye.

    Who knows what sort of effects even just a slight local temperature increase can cause. Perhaps it might stimulate cells to release autocrine growth factors. Perhaps it is enough to significantly speed up the delivery of growth factors via blood or the diffusion of signal transduction elements intracellularly. Of course, the key thing needed to cause a panic is to find the exact mechanism.

    But I really can't see why thermal effects alone can't destabilize DNA or RNA. While the molecules themselves are stabilized by covalent bonds (albeit weakly) and very regular hydrogen bonds (in the case of dsDNA), both of which take a lot of energy to break, their interactions with other molecules, such as those responsible for DNA replication or RNA translation, are much more tenuous and don't necessarily need ionizing radiation to be broken.

I'm basing this on my experience with heating scrambled eggs in a microwave oven (scrambled eggs being the closest food item to brains that I can think of). When heating a small quantity of eggs (2-3 eggs worth at the most) in the microwave I've found that it takes significantly more than 7 seconds to produce any noticable heating. My head on the other hand is much larger than a typical serving of eggs (I'd estimate that it would take about 5 dozen eggs to make up the approximate weight of my head [based on 7 lb head and 50g chicken eggs]). Therefore I suspect that the heating effect of a full 1000W of microwave energy continuously applied to my head for 7 seconds on a daily basis would be minimal. Furthermore, my head has a built in liquid cooling system which would help to quickly dissapate any extra heat from my head and this energy is not being applied to my head all at once but rather spread over the course of 2 hours.

    If you are actually concerned that the heating effects of microwave radiation from your cell phone are going to be dangerous to you, you should seek to remove other heat sources from near your head. The following may be reasonable precautions for you to take:

Women with many children were less likely to get breast cancer than women with only one or two kids, and women with no children had the highest risk. Additional studies confirmed this. Then someone noted that women with larger families usually start having kids at a younger age than women with smaller families, and researched that connection. They learned that the preventive effects were not tied to family size, but the woman's age at the time of her first pregnancy. Pregnancy before age 20 reduces the risk of breast cancer, regardless of the number of pregnancies that follow.

    Since uveal melanoma starts within such cells, there is a ready-made mechanism by which mobile phone radiation might help to initiate cancer, especially in people with a genetic predisposition to the condition.

    This isn't a poor explanation at all. Excessive mitosis alone can lead to cancer, even if one isn't exposed to ionizing radiation that causes mutations. Mutation occurs at a given rate, even in normal individuals. It's up to the DNA replication error correction machinery to catch them.

    Let's pick a random tumor suppressor protein, such as p53. It needs to be at a specific concentration in the cell to be effective at catching replication errors (which occur at a regular frequency even in normal individuals) Protein synthesis only occurs during G1 or G2 while DNA replication occurs in S phase and cell division occurs in M phase. Protein breakdown will continue at a relatively steady rate throughout the cycle, however. If the rate of DNA replication/cell division outstrips the rate at which p53 is synthesized (i.e., the length of time the cell spends in G1 and G2 phase decreases) and the breakdown rate stays constant, you've possibly effectively decreased the concentration of p53 in the cell.

    But regardless of what the actual mechanism is, anything that can cause increased rates of mitosis (growth factors, signal transduction elements, whatever) can cause cancer because of the baseline error rate. Notice that the most common cancers occur in tissue with rapidly dividing cells such as skin and the colon. And it's not necessarily because they're more exposed to ionizing radiation.

    While you're right in saying that it would take ionizing radiation to break the phosphate bonds between adjacent nucleotides, it does only take thermal energy to break the hydrogen bonds that link the base pairs. While you'd need to be at 95C to completely denature double stranded DNA, you'd only need much lower increases of temperature to just partially melt dsDNA enough. At physiological temperatures, dsDNA melts spontaneously all the time. This is why helicase can work, and that's why you need histones to stabilize dsDNA (and the hydrogen bonding between histones and DNA is much weaker than that between strands of DNA--much more easily broken by heat alone.)

    But you're right in saying that a correlation is not necessarily meaningful. Without a mechanism, there's no need to panic yet. But if you take the scientific method to the extreme, nothing is ever true, you can only determine what is false.

For instance, perhaps affluent Brits are more likely to own cell phones and more likely to go on vacations to places to sunny places. People who are normally exposed to low levels of ultraviolet light (i.e. Brits) who suddenly find themselves in sunny climates have very little skin pigment, and are much more prone to get cancer-causing sunburns (or perhaps eye damage) than those accustomed to those levels of sun.

He had a hypothesis to link the two but I did not see any "evidence" to prove that the hypothesis was anything more then considered extrapolation of known facts. Until such time as someone can definatively point to a cause/effect relationship between phone use and cancer, statements like "The study presents EVIDENCE for a link.

    the weaker-energy radio waves (longer wavelengths) and the positioning of antennas relative to the body, but we'll never know, now that cellphones have supplanted ham radios (and at much greater cost).

    The major concern with cell phones and the potential health risks comes from a combination of power and antenna location.
    Originally cell phones operated at as much as 4watts! That's a helluva lot of power to be radiated right beside your skull. Current cellphones max out at 0.6watts.
    Given that most Ham systems are using externally mounted antennas that are not located within an inch of your skull, the exposure is far lower. Even with clam-shell style cell phones they have measured significantly lower exposure ratings as the antenna is being tilted away from the users head.

    Ham radio has to adapt now. We have to get rid of all those stupid restrictions like morse-code tests for liscenses. Anyone can buy and operate a cellphone without a liscense. The same should be true for ham radios.

    As far as cell phones supplanting Ham, and Ham's need to adapt to compensate, this doesn't make a lot of sense to me. They are two very different technologies offering very different forms of communication. Ham is great for some kinds of communication, but is a one to many medium rather than the one to one communication of telephone (cellular or otherwise). Cellular phones also have the advantage of integrating with the existing phone system - it's inherent in the design. Yes, I know you can patch into phones with a Ham if such a repeater is available.

    Getting back to the one to many aspect, it has several problems when you talk about the scale of cellular communication. Since only one person can talk at any given time on a given frequency (within their transmitters range) you quickly consume the available resources. And we don't want to forget responsibility, getting a licence forces Ham opperators to behave themselves (and assumes a certain level of maturity). Think of Usenet in the early days, it was a valuable resource. Now that anybody can post it's degenerated into noise (yes, everybody has always been able to post, but before net communications got to be point-and-click the learning curve acted a lot like a licence). Do you like the idea of people trolling the Ham space? Or having people just keying for the sake of it? Yetch... You also have the problem of privacy: none with Ham. True you can monitor cellular activity with a scanner, but with digital phones and spread spectrum technologies, it's much harder to get anything useful out of it. Besides, I have get to see a hand held Ham anywhere near as tiny as current cell phones.

    Ham is a valuable tool, but planning to use it as a cellular replacement seems like a bad plan to me. But that's just IMO.

      So these JWTBs go round trying to 'protect' everyone. Because everyone is a 'victim' And as you say, we should hold ourselves as adults, and be responsable (ie. choose for ourselves).

      But, in order to make that choice, we need good data. We need information. Do I start smoking for the pleasure of it, or is nicotine sufficiently addictive that I will experience more discomfort than pleasure when I want to stop? Do I use a cell phone for the convenience, or will it increase my risk of getting cancer (remembering that one in three die of cancer anyway... will a cell phone dramatically increse that risk?)

      I think the argument that people are just not dying fast enough is not valid. Sorry, but your logic is silly. And I spend a lot of time being silly, so believe me, I know silly.

      Just because we tolerate x thousand road deaths does not mean anything causing less than x thousand deaths is ok.

      Just because light bulbs might cause harm (people falling off chairs when changing them?), and we accept light bulbs, does not mean we accept any possible hard to detect harm from everything else.

      In talking statistics, we can make chances sound real small. But for the one in a million person who gets that fatal condition, it will kill them.

      Also, we could be in the business of cleaning up this planet. Try hoarding all the garbage you would throw out in a year. Now multiply that by 50. And again by 500 million. It's all going somewhere.

      Cell phones are just another suspect technology because we have wised up to the fact that most of our technologies involve harmful environmental side effects.

      People are taught in school (at least I was) that different types of radiation have different effects, some linked to cancer. Now cell phones emit radiation, and I for one don't know what effect that type of radiation will have. I would like to know. I would like it to be studied a lot.

      Now I suspect that the tobacco companies don't try to prove that nicotine is 'highly addictive'. And I suspect that scientists are a conservative bunch -- 'false' until proven 'true'. And I suspect that politicians will seek to pacify the public and protect the industries -- insert picture of politician feeding burger to daughter here. And I suspect that the environment is treated like some magical tardis where you can dump things and they will 'just dissapear'. Witness latest debate about whether it's 'safe' to eat tinned salmon.

      So the JWTBs seem to target every new technology. But guess what? A lot of our technologies "don't work" -- cars turn a small mistake into a 26 car pile up, television entertains you while your mind and body rots, food packaging preserves the food a few weeks and the packet forever -- I mean, I don't want to be a bleeding heart, but we could all add to this list... is it any surprise that some people worry about mobile phone radiation?

      We are just beginning to ask questions about what the real extent of pollution in the environment is. And in that light, all these 'hard to detect little risks that are a part fo life' may just all add up and wipe our 'responsable' little asses off the planet. We need more research into these things. Not just ignore it as part of 'life is risky'.

Several of the studies have had serious methodological shortcomings and the problem of "multiple comparison bias" (if you make 100 comparisons between samples which are unrelated, you will find 5 "significant" correlations, and if you only highlight those in your report it will give many people (and less scrutinous daily papers) the same impression as if you'd done a study specifically to examine those and actually found correlations).

    Something to be remembered is that uveal melanoma is a very rare type of cancer; its incidence (in Europe) is about 1/30 of that of melanoma of the skin, or around 8/million/year. However, since it's a tumour which causes unilateral visual disturbances/blindness once it expands enough it's one that's unlikely to be underdiagnosed to any significant extent. Thus, the next few years' worth of uveal melanoma incidence figures should point a finger at whether we're doing anything that's increasing the melanoma risk. I don't recall how strong a risk factor sun exposure is for uveal melanoma (compared to other melanomas, for example), but I'd check whether any increase in uveal melanomas was disproportionately larger than the increase in all melanomas. In summary, if cell phones do increase the risk of UM, we'll be able to detect it quite reliably in a few years.
