She was up and about not long after her surgery and the polyp is benign.*
*I was skeptical of this at first. My Aunt can be shady with health issues. For example, the only reason my cousin and I even KNEW she was going to have surgery at all was because my uncle made the mistake of mentioning they'd be home in Auburn, MA this week. Anyway, I always assumed that results such as this require days to get back from the lab. I actually suspected she was lying just so we wouldn't fret while waiting for the results. A co-worker said that in some cases, they can tell right off whether someting is suspicious or not. So...YAY.
And thanks Aithlyn. :)
