In situations like that, we do believe that perhaps giving chemotherapy prior to the operation, with or without radiation treatment, may allow the surgeon to successfully re-sect all the visible cancer, and perhaps may kill the cancer that has moved to some other part of the body. ANNOUNCER: As doctors continue to learn more about lung cancer, there is reason to hope that earlier diagnosis and future treatments will be more successful at combating this disease.
DAVID JOHNSON, MD: We're improving our ability to diagnose this disease, earlier and earlier. I think that's important. I think the message has finally gotten out that cigarette smoking is not a good thing. We don't have nearly as many Americans smoking today as we did 25 years ago, and that's good news.
NASSER ALTORKI, MD: Cancer is found early before it had produced symptoms, preferably at a small size, preferably when it's still operable. All these together substantially increase the likelihood of cure if surgery is performed. For those who have advanced disease, the good news is not quite here, but maybe will materialize in the next few years. I think there will be a substantial explosion of new agents that will come to the field that are more specific in the way they treat lung cancer.
