Why are people in the US getting cancer if they don't smoke? Any research to back belief of air polution?

Question:

I recently saw Gwyneth Paltrow's mom on TV and her husband died of cancer and had never smoked..just got me thinking that as much money that is spent every year on research in the US that we would have more answers to this disease and the toll it is taking on our health care and of all the oncologists, do they have any understanding of the source of this disease?

Answers:
There are several different kinds of lung cancer, and only a few are linked to smoking.

It's a very difficult problem to investigate, as cancer cells have mostly the same DNA as our normal cells. Probably there is something that turns on a cancer gene, and causes a tumor to start growing. The immune system can destroy some of these tumors, but we don't understand why some tumors escape the immune systems defenses. So it's a coplicated dance between or genes, out environment and our immune systems.

I doubt pollution is the cause--19th century London didn't have great air quality, but that didn't cause a spike in cancer.

Other Answers:
