Symptoms of a swollen right tonsil

Hi. I've had a swollen right tonsil for probably a couple of years now. As I had recently also been having the sensation of a lump in my throat off and on, I finally went to the doctor about this and he has referred me to ENT. However, after looking on the internet at symptoms of things like non-Hodgkin's lymphoma, I am slightly worried about it now, as over the past year I have had some other vague symptoms, like itchy legs and a low red blood cell count (although not low enough to be clinical anaemia - also has got back to normal since I started taking iron supplements). I know you can't tell me for sure what you think this is, as you can't examine me, but do you think it's likely to be some kind of cancer? I'm not just asking for reassurance, I would prefer an honest answer whatever that means. Thanks.
