Early trials show a breath test for lung cancer detection may surface in the not-too-distant future. And it could be simple, inexpensive, non-invasive, and effective too.

The tests needs a good amount of work still, but if we keep our fingers crossed and medical researchers stay hot on the trail of this test, it just might be possible to one day spot lung cancer by simply breathing into a device for a few minutes.

The lung cancer breath test measures chemicals called volatile organic compounds (VOCs) in the breath. There's a certain pattern of VOCs associated with lung cancer, and they show up as colored dots across a quarter-sized panel.

The theory behind this test is great. The test itself is not perfect yet, however.

It's promising, though, says The Cleveland Clinic's Peter Mazzone, MD, MPH and colleagues who describe the test in the Online First edition of the journal Thorax and reveal the test correctly identified in studies three out of four people with lung cancer and detected lung cancer almost as frequently.

Apple CEO Steve Jobs delivered a commencement speech at Stanford University on June 12, 2005. It was about following curiosity and intuition, about looking back and connecting the dots in life, about beginnings and endings, about death. Jobs, a survivor of pancreatic cancer, knows a thing or two about facing death. And the words he chose to relate his life-threatening experience to a crowd full of hopeful graduates are powerful and inspiring. I could paraphrase his message -- but surely something would be lost in my translation. So here is a bit of what he said -- word for word.
