Then what would the doctors blame lung cancer on?
Get tobacco entirely out of the picture and there will still be lung cancer.
Whatever your beef with smoking, we would all be better off if all the money pissed away on lame ad campaigns, stupid billboards, and propaganda crusades had been spent on basic cancer research and finding cures for cancer regardless of what the cancer is blamed on.
You are right. Don't forget Linda McCartney died of breast cancer, and she was a clean living, thin vegetarian. But that doesn't stop groups from claiming that it's caused by hormones in meat.The fact is we don't always know what causes some people to develop cancers. Cancer arises in all organs of the body. Why in the case of lung cancer does it HAVE to be because of tobacco?
