I have a swollen lymph node on my neck and I have a sore throat and a bit of a cough does this mean I have leukaemia or throat cancer. I have been on Google and it saying leukaemia and I'm worried if this is true. I have a complete blood test but that is to do with my anxiety to see if I have Anemia. But I also read if you have Anemia you have high chance of having leukaemia so either way I'm just in the mud.
