Ditto for me you're young - it's very possible it's nothing but because you're young Drs tend to skip over the idea that you might have cancer - so push of a biopsy - and money means nothing next to your life. I have to say I had an undiagnosed tumor for 6 years - when I finally got a positive on the biopsy - I had a ct the very next day that said no nodes involved - this was dec 21 - by dec 28th I could feel a swollen node - when I was operated on they removed a whole whack of nodes, and one - the one I was palpating - was positive. this can spread quickly once it starts to. get to a dr. ASAP. Good luck!
