Confusing medical conditions

So I've had this thing on my eyelid for a month or 4 - don't know when it came up, it doesn't hurt, I only know it's there when I look in the mirror:

So I asked my GP & apparently it's a cholesterol deposit. On. My. Eye. The first thing he said: "do NOT try to excise it yourself". Dammit, it's annoying how well he knows me.

Since my cholesterol levels have always been good, I queried this being the Portent of Doom the GP seemed to think it was, and went looking. I found an article (side note: in which pregnancy is referred to as "a medical condition" - wtf?).

Turns out, according to this, it could mean OUT OF CONTROL LIPIDS RUN FOR THE HILLS. Or, it could just be a cholesterol deposit and not "mean" anything. I'm not a fan of ambiguous symptoms - it should be an either/or: "death cometh" or "you'll be fine".

Since I got my bloods done last week in the lead-up to surgery, I've asked the surgeon's office to let me know if there's an actual problem. *le sigh* One more thing on the list, I guess.
