All these results (re 'shown to be carcinogenic') are based on surveys as opposed to experiments. In other words, unlike randomized, double-blind studies, they cannot be said to demonstrate causation, but at best may point to interesting hypotheses. As for eggs and cholesterol, about 80% + of cholesterol is produced in the liver, and increasing dietary cholesterol by HUGE amounts at best changes blood cholesterol by 2-4% Sorry I can't dig up the study right now, but perhaps searching pubmed may find it.
