My ENT did not seem worried at all when I went to the appointment. He said that the enlarged lymph node was only 5 mm and even though it is slightly hard, it's mobile. So he prescribed a 5-day treatment of Ketex because he thinks that perhaps the last antibiotics weren't strong enough or my infection developed a resistance to it. My mother shared with him my fears of oral cancer (and other cancers in general) and he did feel around a lot for other swollen nodes, plus down my throat and everywhere around in my mouth (from what I looked up on the web, I think that was an oral cancer exam). He says he really doesn't think it's cancer, especially since I have acne and that might also be causing the swollen node (for which he prescribed a cream). I also had a 100.4 fever when I went, plus the previous CBCs also indicated an infection. So I do feel a little bit better, but I'll be going back in 2 months and if the nodes are still swollen, then he may request a biopsy (he said at this point it was too small to even get a tissue sample using FNA).
