How the NLST has found a breakthrough method to screen for lung cancer, and how it may save millions of lives.
On a personal aside, being in the medical physics field, I can't help but marvel at how much of an impact a simple screening process by an x-ray machine could turn around survival rates for a particular disease. To me it seems that medical imaging and radiation medicine in general are slowly achieving for cancer what vaccinations effectively achieved for communicable diseases, prevention or eradication. The field is not there yet, not by a longshot, but hopefully that is where it will end up in the future. As always, I remain painfully optimistic.
