Brief summary
The feeling of shortness of breath is very common in lung cancer. It is uncomfortable for patients and upsetting for their family. Although drugs like morphine and oxygen can help some patients feel better, they don't help everybody, and they are not used in patients with early symptoms. More relief is needed for these patients. The investigators are studying a drug called tiotropium, which is used in emphysema. It is an inhaler that opens the airways to allow easier breathing. Every patient will get the drug but also a placebo, in a random (flip of a coin) order. They will get each for 2 weeks. The investigators will see if they feel better with the drug.
