I especially like how it explains the meaning behind the oft repeated mantra that cancer is not a single disease, or that cancer is not a single disease therefore there will never be a cure for cancer. Both these statements reflect true facts about the nature of cancer, but out of context they sound like weird illogical platitudes.
