I just want to confirm really that this is okay because I've been scared of having thyroid cancer since March i've had blood tests ultrasounds etc and I just wanted it confirmed that the lump on my thyroid isn't cancerous. 

I was booked in for an ultrasound today. I have had 2 before this in recent months but I didn't have the needle and the doctor I last spoke to isnt sure why. 
The radiologist has told me that the lump on my thyroid has gone from U3 to nearly U2 so has gotten smaller and so he did not feel that he needed to do the aspiration. He said the guidance now says not really to do them on lumps under 2.5 cm and mine is 9 mm. I should also mention at this point I originally went in for swollen lymph nodes and this lump on my thyroid was found and I was told it could potentially be cancerous but it's not high risk essentially. I also have no other symptoms.

i've also been told by my consultants receptionist that it isn't uncommon for them to decide to not do it and that's obviously what happened to me before and that it's up to the radiologist. I'm just a bit baffled as I was expecting the needle and my partner is angry about this. I've contacted my consultant for his opinion on this decision and I just wanted to get some opinions on here as well. 
thank you so much for your time.
