a new means to detect lung cancer

now here's a pretty cool thing. they've known for a while that the
lungs give off a volatile organic gas when cancer is present. they
finally developed a
test that is around 75% accurate in diagnosing lung cancer.
how cool is that? we had a very dear friend die of lung cancer last
year, and had the doctor used this tool early on, Karin might still be with us. since the test is inexpensive, i can't imagine whydr.s wouldn't use it as a matter of course for anyone with respiratory issues.
of course, if they were to sell this over the counter, the hypochondriacs still wouldn't be comforted, since there is only a 3 out of 4 chance of detection.
