I am curious to know whether breath testing for lung cancer has been approved or currently exists. I read Dr. West's article from 2008 regarding breath testing being developed, but has there been any progress in the 8 years since then? (Seems like a long time.) And also, has there been any progress in the field of breath analysis done by laboratory dogs?
CT and PET scans as the standard diagnostic and monitoring methods take their toll on the patient, especially when we have CT scans every 3 months and semi-annual PET scans as well. I will jump for joy the day that someone comes up with reliable alternatives to using these radiation scans for lung cancer diagnosis and monitoring!
