Actually, it's some background information and your blood that's needed.

Memorial Sloan-Kettering is running an important trial that is trying to determine some of the molecular factors that lead some never-smokers to develop lung cancer while other never-smokers don't. The trial is just a one-time collection of information in a questionnaire, I believe about medical history and environmental exposures, and submission of two vials of blood. There is no cost to participants, with all packaging and mail expenses pre-paid, and the registration and additional information is online here.

This is an important and timely question, and the researchers at Memorial Sloan-Kettering have been among the most important leaders in developing our understanding of the biology of not only never-smoker lung cancer, but also of lung cancer in general. I strongly encourage any never-smoker with lung cancer to participate.
