Found a lump back of my neck

Hi everyone 

for around a month I have a lump in back of my neck , so gone to the doctors today and he has ordered a full blood count. He is also referred me to ENT . I've already been referred with my ears so he chasing this up as urgent as not been seen as was referred over a month ago. He thinks the lump and ear issues are not related. Worried and scared! Automatically googled my symptoms and comes up with the C word!! 
 

any advice? I'm probably overreacting and worrying over nothing. But worried about longer I'm gonna have to wait for my appointment with ent or will my gp put it on urgent??

 

thanks Hannah x
