New promising research on catching lung cancer early has a lot of people excited. A recent trial found high risk patients for lung cancer who were screened with CT scans discovered cancer at an earlier stage, resulting in an improved survival rate. St. Charles Oncologist Dr. Steve Kornfeld says the results are promising. “And if you can detect cancers at an earlier stage than a later stage then theoretically they’ll be more cures. It’s similar to the whole idea behind mammograms; finding breast cancer before you can feel an abnormality. And then hopefully find them at an earlier stage.” Dr. Kornfeld says the results are too preliminary to become standard care. There's also a concern about the cost. It would cost a lot to screen a lot of people, who might undergo invasive procedures, with little improvement in cure.
