Like, sorry, but I fail to understand why we should bother trying to develop a vacine for lung cancer, eh? We already have a cure for lung cancer. We also have cures for Aids, Syphlis, Gonoreah, even though it can't be spelled. We also have a cure for skin cancer. There are probably more cures out there for other cancers and other diseases that more learned people then I know about. [log in to unmask]
