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.

      Chedar, your wife gets CANNED kimchi?! At least I get the kind in a jar! NASTY!!!

      I have several cell phones, each to its purpose, I switch SiMM card as needed (all unlocked from overseas).
      I barely use the things. As in prepaid (cost isn't worth a monthly bill for MY use) and go until my money isn't worth anything any longer and I have to pay yet again for minutes that I'll not use.
      Funny thing, when I was deployed overseas, I had those same phones there, postpaid (regular plan, but NO CONTRACT). Used the things to death, but STILL wasn't welded to the things.
      But, they came in handy when I was on leave, in spite of the bill, as I got calls to bail out the guys still there in the war zone, while I was on leave. It always gave me a chuckle doing that, from half the world away.

      As for coffee causing cancer, yet it protects us from cancer, yet it does nothing to cause or prevent cancer, yet it causes it...
      My dick causes cancer, per some studies (OK, male members in general).
      SHUT DOWN PROCREATION! IT CAUSES CANCER!
      Oxygen has been PROVEN to be linked with cancer. Every creature that consumes oxygen gets cancer in general.
      BAN OXYGEN!

      Or just wear sunscreen, don't smoke, exercise, and eat a healthy variety of foods (especially fruits and vegetables).

      a lot of these risks are very minimal. It's like freaking out about the 1 in 1 million chance the MMR vaccine will give your child encephalitis when measles has a 1 in 1000 chance of death.

    Hmm..only a thought.
    Does the plastic found in our coffeemakers have anything to do with the problems? (besides these bogus studies). All that hot beverage flowing through a plastic cant be good, which we then consume.

      Agreed. Last year, I started using a stainless steel kettle, a ceramic pour-over dripper, and a glass server. I stopped using my coffeemaker because I was curious about whether the plastic made a difference in taste. But then I also realized that the plastic might be leaching chemicals into the boiling water. So now I drink better tasting and (hopefully) healthier coffee.

    Look – the Interphone study was quite large (30 countries?), and while not statistically conclusive the data (which was sizable) SUGGESTED a 2x risk of certain cancers in heavy users (10 yrs at 30+ mins/day). That data – 2x the # tumors on the side of the head the phone was used in a very large # of datapoints.

      Actually it was more like 5 hours per day for 10 years. It was really a ludicrous exposure group and greatly prone to recall bias.

      Also, don't forget to mention that if you used your phone for less than 5 hours per day, you were actually protected from cancer (significantly lower risk).

      One of my pet peeves is political decision making based on poor or misinterpreted science.

      There was a study done about 20 years ago that showed that caffeine caused cancer in lab rats. The interesting thing is that once people looked at the size of the rats, and the amount of caffeine they were given; it was determined that a human would have to drink 700 cups of coffee a day to get the same result and effect.

    Enough already! I remember in the late '60's they took diet soda off the shelf because they said it could cause cancer. My father in law bought up all he could get. He'd read the fine print. It would take literally cases of soda every day to cause cancer. I have friends who don't use deodorant because they read it could cause cancer. One won't wear a bra for the same reason. I use my cell only to call the phone company when my landline is out because I am homebound. But if I was out I sure wouldn't worry about the cell. Every day somebody comes up w/ something new that will cause cancer; the healthy food guidelines change constantly. At this point, I'm reasonably sure you could find somebody who would tell you that everything we eat or use can cause cancer. It's beginning to sound like Jim Jones had the right idea, tho for the wrong reasons. Why don't we all give up food, water, clothing, and die in a couple of weeks before something else we're doing, eating, using can give us cancer? I know one Italian word, and it fits well: BASTA!

    Everything causes cancer, from the air you breathe or sunlight on your skin to any animal meat you consume into your body. Cell phones are particularly bad among everything you touch. Americans should concern how honorably they can live and raise children of good character than how long they can live and have more fun, just like their ancestors did. Long human life of stupidity and selfishness is meaningless and is bad for the planet, too.

You are not a goddess and you can never be because you are too ugly. Admit the hard fact. You are just ugly, power-hungry abuser of man when you claim to be a goddess. If you want to be truly beautiful, learn to be submissive to your man, unless he is a criminal.

    It's not the coffee that kills you...it's the rainbow oil-slick of third-world carcinogenic pesticides and herbicides that floats up to the top of your cup of Joe that will kill you.

    All these coffees are just mixed around and randomly dumped into plastic cans of coffee by the Folgers and Maxwell House canneries, so sometimes the coffee is good for you because it has almost no carcinogens...but sometimes you get a batch from a pesticide-loving nation, and it starts to kill you.

    Being a radar tech for the USAF for the last 15 years its just plain common sense that cellphones can raise the risk of cancer. There is a ton of warnings we must abide by for our equipment for wartime ops and to even take a low power unit such as a cell phone and place it next to your brain seems totally idiotic when you stop to think about it. Folks go out and buy the ear piece with the mike that is corded. Keep that unit away from your body as much as you can. I own a cell phone yes but it rarely gets next to my head. Hands free in the car or corded on the desk at work.

    2. Some people in this world will get cancer; and some people won't.
    3. Some of those who get cancer will die, and some won't; but either way, at some point in the future, everyone will die.

    Good article that puts things into perspective. Thanks. The fear over cell phones is completely ridiculous. As an RF Engineer, I understand the difference between ionizing and non-ionizing radiation. Apparently the WHO expert panel doesn't. The difference in wavelengths between cell phone emissions and high-energy ionizing radiation is like the difference of being tapped with a plastic baseball bat vs. having your body pierced by a sub-atomic sized needle. Hint: The ~1 foot wavelength of a cell phone emission is not going to cause DNA damage. The wavelength of a gamma-ray will.

      Interestingly enough – though I am a physicist and agree with you – is that they consider "frying" a possible cause of cancer. Apparently exposure to high temperatures over extended periods of time can cause cancer – and I think some people – those at the WHO – are worried about the microwave radiation given off by cellphones. I won´t swear by it, but I have to say that I am starting to be more careful with how I use my cellphone, just in case. I still use it – but try to use a hands free device (not a wireless one) whenever I know I will be on the phone for extended periods of time...
