We don't understand very much about this at all. It's primarily due to the federal government not providing funding commensurate with this disease's death toll. We need to have more research done. That's the only way that we are going to end up saving lives.

Dana Reeve's death highlights the fact that lung cancer is the leading cause of cancer death in women in the U.S., claiming 30,000 more lives annually than breast cancer. It is not unique that she developed lung cancer as a non-smoker -- at least 1 in 5 women with lung cancer have never smoked.

To me the fact that we don't have a screening test for the biggest cancer killer in the nation is the best indicator of how little resources have been put toward this disease. It is absolutely abhorrent to me that we don't have a screening test for this disease.

It's a sad thing that it takes a celebrity's death to highlight that this is the leading cancer killer of both men and women.
