Upcoming appointment

Hello I went to my GP over 2 lumps in my neck. I had an urgent referral to Vincent’s for an ultrasound which I had last Wednesday. The lady doing the ultrasound said my lumps looked like normal lymph node’s but that the radiologist would need to take a look etc. I received a text today with an appointment to see the ENT consultant on Friday. Now my concern is why am I being called in so quickly and also if nothing showed up in my scan would the results not just be sent back to my GP ? Should I be concerned.
