Coffee, pickled veggies also 'possibly' cause cancer

Coffee, pickled veggies also 'possibly' cause cancer

As you continue to weigh the risks and benefits of using your cell phone, in light of the recent World Health Organization announcement that the phones may lead to cancer, consider how scared you are of pickled vegetables, gasoline and magenta dyes.

These are just some of the substances also lumped in the same group of "possible carcinogens," formally known as "group 2B carcinogens" on the WHO's International Agency for Research on Cancer's list of known, likely and maybe-likely suspects.

In fact, coffee is in the same 2B category as cell phones because of evidence that drinking coffee could be associated with cancer of the large bowel. On the other hand, coffee was also recently linked to a lowered risk of fatal prostate cancer, so go figure.

And pickled vegetables, in case you were wondering, have been thought to increase the risk of gastric cancer, possibly. A meta-analysis of studies on Japanese and Korean populations, in which researchers looked at a bunch of studies that had been done in the past, found this association. Study authors concluded that a high intake of fresh vegetables, not pickled, is important for lowering the chances of getting gastric cancer. But, like studies on cell phones, this is based on observational data - information gathered about people's past behaviors, which were not in a controlled scientific setting.

By comparison, tobacco - both smokeless and smoked, as well as second-hand smoke - is in group 1, which means it's considered cancer-causing without question. This group also includes ultraviolet radiation types A, B, and C, which comes from the sun - the reason you want to wear sunscreen and protective eye-ware when you go outside this summer. The WHO is clearly not as sure about the harmfulness of cell phones as it is for these common carcinogens.

The next group down, classified as 2A, are "probable" carcinogens, which include a variety of activities such as manufacturing art glass and art containers, manufacturing carbon electrodes, and exposure at work from being a hairdresser or barber. It also includes indoor emissions from combustion of wood and other biomass fuel, and shift work that disrupts circadian rhythm.

This is all to say that it would be quite premature to say that cell phones are "the new tobacco," since the evidence for cell phones causing cancer isn't nearly as strong as it is for cigarette smoking leading to the disease. In fact, according to these classifications, we can merely say that the cell phone is perhaps "the new pickled vegetable." Hm, that doesn't sound as foreboding.

Here is the complete list of substances, exposures and activities that the WHO has classified as known, probable and possible carcinogens.

And here are tips for minimizing your radiation exposure from cell phones.

    I'm just speculating, but this seems like a cell phone attempt to dis-credit the ranking. However, when you really think about it. I mean REALLY think. I think the ranking the WHO gave cell phones is low to begin with. Take this article for example. Drinking coffee, eating veggies, touching gasoline, yeah makes sense, I could see these being a 2B rank of possibly being items that might cause cancer. So then conside cell phones. And for that matter all wireless items. We sit in our bedrooms, our houses, or work places and are hit in the head all day long by wireless radio waves. And these come from not just a single item like just a cell phone. We have wireless internet, wireless cell phones, wireless house phones, wireless keyboard, wireless mouse, maybe wireless headphones. And all these wireless signals are hitting us in the head all day long! And then the WHO ranks them 2B similar to 1 coffee a day. I'm sure you see it now and are saying the same thing "You have to be kidding me!"

    Maybe one single wireless device used spuratically throughout the day MAYBE could be rated 2B. But not all the wireless devices we use all day long every single day. I think the rating should be much higher. And I believe unfortunately we will not find this information out until it's too late, b/c in this country money is more important then safe products and lets face it wireless business is a HUGE money maker.

    I write this using my wireless keyboard with a wireless mouse, on my laptop using my wireless internet, with my Iphone sitting on the table next to me. So yeah, i'm just as screwed as you are.

      And the point is, as severl oncologists I saw interviewed say, is rates for this particular type of brain cancer have remained steady, despite the fact that Americans are bombarded with low-dose radiation every day, and cell use has skyrocked - although minutes used per month have declined with the rise of texting.

      I may change by opinion in 5 years, but I am not worried - and I am a cancer survivor.

    Looks like the cell phone industry owns a part of cnn too.
    My thinking on this is that all medical expenses related to anything that can be proven to be a carcinogenic that also has a tax associated with it, such as cigarettes, booze or cell phones, should be fully covered by the government. In fact,families of smokers, drinkers and cell phone users should automatically be given a 1 million dollar government life insurance policy payout when the user dies. It only makes sense.

    Is anyone else as frustrated as I am at all the voodoo science lately? Is there any wonder we ignore these idiots? Perhaps if they took the time to really analyze results rather than constantly guessing and changing their minds, (in this case in a week), we might actually heed them. With this latest fiasco, I'm truly beginning to think all this amounts to is a scare tactic to get more research money and media attention and much less about true science.

    Hey folks, we're all going to die sooner or later. EVERYTHING causes cancer, heart disease, etc. People live t 100+ by eating eggs and bacon everyday with a fifth of Jack Daniels. Some exercise for an hour a day, eat fresh organic veggies and die at 40. Just LIVE your life and know it's short. Coffee, cell phones, whatever... something WILL kill you and probably not what you expect, so be good and live well.

    Just shows you how alarmist these warnings are and how silly people are for worrying about this stuff. I will keep using my cell phone, drinking coffee and eating pickles. Life kills everyone. Your likelihood of dying in 100%. It's best to enjoy life while you can and stop worrying about things that "might" harm you. Driving a car to the grocery store is far more dangerous than using a cell phone (unless you are driving and using a cell phone), and I don't think people are going to stop driving soon. I actually think the WHO is irresponsible for issue warnings based on observational studies which are easily manipulated and often innaccurate. WHO should spend its resources preventing known and confirmed threats.

    According to the complete WHO list, coffee has an *inverse* relationship to cancer of the large bowel, so it might actually help prevent it, not cause it, right?

    It looks to me like coffee made the rating because due to a possible link with cancer of the urinary bladder.

    I like what Jim970 said, anything can practically be proven to cause cancer. First you hear coffee is good, then bad, butter better than margarine, etc....now skim milk is bad, better to drink whole milk. .....Oh but if you have heart disease in your family that might be bad. All these studies give me anxiety, I just try to eat everything in moderation, as I know if I load up on one particular thing, 10 years from now I'm going to here "oops, that might cause cancer". ughhh I still maintain genetics play a huge role in how long someone lives.

    The sad fact of the matter is this: in this country health care is a nothing more than big business at it's filthiest. One day it's published that coffee can help decrease the likelihood of contracting fatal prostate cancer, so coffee sales go thru the roof. Not long following that, you read coffee can cause cancer. And it's the same for eggs, butter, cell phones, juices, sugar, gluten, and on and on. There is not end to it because it is all designed to make huge profits for the health care industry and other big businesses. In addition to that, there is seemingly a new drug to treat some ailment on the market every few months. Isn't it curious though that the drugs presented for public use seem only to control or mask symptoms so that you can live with the ailment. That way you must continue visiting the doctor and continue buying the drugs. None of these so called Dr.'s are trying to cure you...none of them or the drug companies. You know why? Because there isn't any money in the CURE. The money is in keeping people sick or just marginally better, just we they have to keep on spending our money to feel a little better. Health care and insurance are two of the biggest scams in America. And, unfortunately, there isn't much the average person can do about it except work hard to never get ill.

    Coffee – at least the junk most people drink – is one of the most heavily pesticide sprayed crops. And decaf coffee – if not using a Swiss water process of decaffeination – has the caffeine removed by a chemical process using toluene that extracts the caffeine and supposedly removes the carcinogin solvent. Supposedly. I asked a chemical researcher at a Petersburg, Virginia, plant owned by BIChemicals about the process. He allowed that "trace" amounts of the toluene remain. One man's trace is another man's cancer. It doesn't take a rocket scientist to put two and two together. Stick to Fair Trade, organic, coffee, that isn't sprayed with pesticides nor treated with solvents – and enjoy. Avoid Starbucks and the like.

    Drink lots of coffee (to prevent prostate cancer) and take lots of vitamin D (to prevent both colon & prostate cancer). Very, very, very few people with an adequate blood level of 25-hydroxyvitamin D (between 40 & 100 nanograms per mililiter of blood) develop either of these cancers. The problem is that with our modern-day limited sun exposure, without taking supplements it is very hard to get your vitamin D level into that adequate range.

    Has anyone considered that it's "The Laboratory Mice" that cause cancer? They determine whether we live or die.

    My real question is how many rads did they bombard these mice with?

    Remember the Cyclamates from the late '60's. The amounts they gave the mice were equivalent to consuming a six pack of soda, each day for 50 years.

    Having watched a loved one slowly dying of cancer, I can tell you cancer is no laughing matter. It's not a matter of going to bed one night and not waking up in the morning. It's more a matter of a painful deterioration of the body until the body finally gives up. I don't know what does and does not cause cancer, but when someone with expert knowledge of the subject tells me that some activity may cause cancer, I pay attention.
