There’s a lump but scan didn’t show anything???

So after waiting 3 months for a fast track ultrasound I have finally been seen. My gp made a real mess of my referral and sent it off incorrectly  

Now it has completely thrown me as they could not detect the lump on the scan but yet the person scanning said it can clearly be felt. I asked if that meant I could stop worrying and he just said I advise an mri of the neck to see what’s going on. 

Surely if it hasn’t shown on the ultrasound it means it’s not cancer? Not sure if anyone has been in the same situation and can put my mind at ease. I’ve had/felt this lump since July and I just want answers but all I seem to get is more questions.

 

Thanks
