The article someone shared earlier suggested that there might be some extremely-mild correlation (no established causation) between PC progression and eating more than 2 egg yokes/week.

That said, correlation in one or two studies is very unreliable, because the cause could be an unknown third factor (e.g. people who eat a lot of eggs might be more likely to overeat other foods).

High cholesterol is a whole different thing — we *know* that too many egg yolks are harmful there — and moderation is always a good idea, but there's no need to self-impose too many dietary restrictions because of a few isolated studies.
