I hope everything turned out well for you, Karen and lollypopgirl
I'm a little worried for similar reasons. The Doctor just identified a lump on my neck as just a cyst, but also put me down for a routine blood test and an ultrasound scan -for reasons that have nothing to do with the cyst I went in for, actually: she thinks my thyroid is a bit swollen.
The word 'routine' doesn't seem to be being processed by my internal computer though. I'm sure there are LOADS of reasons for a swollen thyroid that are neither cancerous, not a symptom of thyroid disease, (but I daredn't look for them because googling is usually a mistake!)
Had the blood test today. Just waiting on the other thing now.
