Extremely Accurate Nanotech Cancer Test Developed 128

Posted by Zonk from the adventures-in-inner-space dept.
Sylvestre writes "Medical News Today reports that Harvard researchers have developed an accurate test for cancer using nanotechnology. From the article: 'Harvard University researchers have found that molecular markers indicating the presence of cancer in the body are readily detected in blood scanned by special arrays of silicon nanowires -- even when these cancer markers constitute only one hundred-billionth of the protein present in a drop of blood. In addition to this exceptional accuracy and sensitivity, the minuscule devices also promise to pinpoint the exact type of cancer present with a speed not currently available to clinicians.'"

      Wouldn't easy, reliable testing be good for hypochondriacs? Then they'd be able to tell, conclusively, that they're not sick!
      • The nature of the hypochondriac is that no diagnosis is ever good enough.

        "Well, maybe I administered the test wrong...I'll just go back to the store and get a few more so I can try again...then I'll call my doctor..."
        • You're exactly right.

          That is how my gf and I felt when she took some pregnancy tests after missing her period. After two of the three in the box said NO, we wondered, "Hmm. Maybe this was a bad batch and we should go back and buy another brand?".

          No, we didn't do it, but it was difficult not to and to just trust that the test was accurate.
      • There's something wrong with everyone. It would just flood hospitals with all of the hypochondriacs worrying about false positives - or, as mentioned above, false negatives.
      • There's zillions of things that could possibly go wrong with the human body, so a guy could go broke testing for every possible disease -- assuming the disease has a biochemical indicator. Also, a common view point for hypochondriacs is that if you don't have 'it', that doesn't mean you can't catch 'it' tomorrow. These test kits could be like crack to these people, having to keep going back to the pharmacy for their weekly fix.
        • True, but I don't feel that these things, given that they 'could' be abused by a hypochondriac, should be banned or restricted. They'll be a vast overall benefit.

          Of course, it's not likely to be over the counter for a long time, given that they're going to be disposable 'chips' that are plugged into a multi-thousand dollar machine to interprit the results. Each chip will be cheap*, so it'll be part of your annual physical, and allow faster cancer diagnosis, as well as for other diseases.

However, each marker you want to test for requires that another vial of blood be taken and costs around $100.

    • The point is not being able to detect cancer in 5 minutes and cheaply. The point is being able to detect cancer in it early stages. The sooner you are able to detect it, more chances you have to remove/combat it and avoid its spreading.
      • Perhaps you don't realize that they already have such tests and they work reasonably well, even though they don't use nanowires. These tests are easy, painless, relatively quick, but a bit too expensive for people to do them all the time "just in case." The way it works today, once you *suspect* cancer, then you fork over the money because the tests are a drop in the bucket compared to treatment (of any kind).
