    It won't be a biotech "killer app" since biotech companies are working on genomic and proteomic application. By definition, biotech involves altering DNA on organism (usually bacteria) and selling a protein or procedure derivated from it.

          You're only making things worse. You misquoted (perhaps intentionally) to further your definition in hopes that no one would find the Dupont site. The actual line you're quoting, sans elipsis, states, "Transgenics (often referred to as biotechnology) is the application of scientific knowledge to transfer beneficial genetic traits from one species to another to enhance or protect an organism."

          They are clearly talking about the field of transgenics, which is what you called 'biotechnology', they were merely stating that it is often called biotechnology, but with the implication that biotech refers to a much larger spectrum.

          Even further, if you would have followed the link to the Biotechnology Industry Organization (BIO)'s glossary, you would have found that they describe biotechnology as, "Biotechnology - [bio.org]
          The use of biological processes to solve problems or make useful products." under which the product in question would surely fall.

      Problem with dogs that are trained to sniff anything, be it drugs, bombs or cancer vs some man made technology is the inconsistency between dogs and dog trainers. Although, they may be more sensitive than any man-made device, they also have bad days and can get sick without their handlers noticing. Better to have a device that while not necesarily more reliable or sensitive, might be more easily tested for variations in performance. In other words, are dogs really going to be accurately tested every day to make sure their performance isn't slipping? But maybe a device can be tested more easily and regularly to ensure quality.

      So, why are dogs so heavily relied upon at airports and for other security. Because simply put, security doesn't need to be 100%, it is largely the deterrent that the dogs provide that provides the actual security. Knowing that these dogs are being used will deter the less serious drug smugler or terrorist from the attempt. But with something like cancer screaning you really have to have a high degree of certainty and invariability in order for it to be useful.

      So the reason dogs wouldn't be used is that they just add to the cost of diagnosis, but can't rule out cancer to a high enough degree, making additional more invasive diagnostic procedures needed anyway.

      If this electronic device can be 99.9% accurate at determining that a person doesn't have cancer when used properly, then you can then focus resources on those remaining. Which is better for those that are shown to be clear of cancer. But it also changes the economics for those devices that require greater capital expenditures, they are only economical when used on larger numbers of people, but if this screaning reduces those numbers of false positives, then a fewer number of truly sick people will be left paying for the more expensive machines. So either the number of expensive diagnostic machines will need to be reduced, the price will have to come down, or the cancer sick individuals will be charged more money.

        This isn't because microwaves cause cancer--there still is no consistent corpus of evidence to support that hypothesis and there may never be--but rather because they cause heating. There are proteins within our bodies' cells that begin to denature at around forty degrees celsius. At or above this temperature (which actually isn't particularly warm), the proportion of exposed cells that die is a function of temperature and exposure time. (See, for example, James R. Lepock, "Protein Denaturation During Heat Shock" in Advances in Molecular and Cell Biology, Volume 19, pages 223-259, for an excellent survey of current thought on the mechanisms at work.)

        So microwaves are dangerous because they cause heating. Not only that, they can cause deep heating in localized hotspots. In other words, you may actually do damage to the brain, eyes, and other organs very quickly without having to burn through the layers on the surface first. (This is what makes microwaves more threatening than the stovetop. The heating elements don't burn unless you come into close contact, and they can't burn deeply without lengthy exposure.)

    I find it difficult to believe that the system it uses will actually produce accurate results. The human body surely has lots of tissues in different structures and densities, and also of course there are lots of different types of cancer.

If you've ever seen a small cancerous mole, for instance, you will understand.

    This is the key point - without peer review, there's no way of verifying the claims of a company that is obviously in marketing mode.

    Searching Medline for "Tissue Resonance InterferoMeter Probe" or "TRIMprob" turned up ZERO matches. Without good evidence, there is no reason to take this seriously as other than marketing fluff.

    A quick scan and you could rest assured that your phone wasn't giving you cancer.

    Until it does, that is.

      Cute, and it might be handy for detecting otherwise hard-to-see lesions. Of course, you're still screwed--and not in that fun way--when it comes to AIDS. Detecting the virus or associated antibodies is going to require some wet chemistry--again, not the fun kind--for the foreseeable future.

    The article opens with comments about "40 minute MRI and CAT scans", and "the narrow tube of the MRI scanner". It proceeds to state that an MRI costs "$1000 of the patient's money". While the first two were maybe true a decade ago, the days of even a 20 minute MRI scan are long gone. The medical imaging business is half about diagnostic quality, and half about patient throughput.

    By speeding up the scans as they've been doing since day one, they get more patients through during a day, allowing the scanners to be more profitable, and for the costs to go down. The $3,000,000 figure is awfully high for even a high-end MRI scanner these days.

    This might very well be an interesting, promising device. But, making it look as if it's really good, by presenting deceptive information about the current options, is a huge red flag as far as I'm concerned.

    If it's really a useful device, present it as it is - don't lie about the other technologies. If it's that superior, the marketplace will find it and respond accordingly.
    • Check out this company [infraredsciences.com]....they have a way of detecting breast cancer that no one is using...works better than Mammogramms or Sonograms and it's cheaper than all of them. I think it's time we started paying attention to the new technology instead of just assuming that the old stuff works fine. Alot of people are dying of cancer and the numbers are only rising.
      • Yes, there is good new technology out there. My point is, lying about the current technology isn't the right way to promote something new. If the product is good, time will prove it out. If it's not, then one conclusion about their methods is that the only way they can look good, is to lie about the other technologies.

    The case of "MRIs on demand" shows the problem of ambiguous medical tests. There are firms all around the country that will perform and interpret a thorac MRI for as little as $500. Typically they find find dozens of "anomalies", that are probably harmless. However, it may cost thousands to track these down, including in some cases biopsies. Especially since the people who voluntarily solicit these MRIs are worry-worts in the first place. Medical economists suggest that test with lots of false-positives are economically counterproductive in an already expensive medical system.
  • This would be great if it could become inexpensive enough for anyone to have. Just do a quick scan of yourself in the morning, along with brushing your teeth. "Oh good, no cancer today!"

    It's about time that the medical community looks for less invasive ways to detect and treat disease. If there is one disadvantage of modern medicine, it's that it requires more probes, pokes, and pat downs to diagnose illness. Sometimes I'd rather be sick...
    That being said, this wand is great for being able to let you know NOW whether or not you have a tumor. That in itself is worth the advance.

  • Precision and recall (Score:2, Insightful)

    Different forms of medical devices have different requirements for precision---that's the percent of things they report that are correct---and recall---that's the percent of things they are supposed to find, that they do find. Before this could replace an MRI as a primary diagnostic tool, it would need to have 100% recall. Precision is less important, because if you do get a false positive, you can go in for further testing (which is not to diminish the stress and fear induced by false positives).
