can lymphoma cause small "tumors" on neck?

i have two small lumps under my skin right on top of the muscle, they feel hard and rubbery, one is near C1 to the right about a 1/2 inch, the other is near t1- t2 to the left about an inch, could these be simple lipomas, mesenchymomas, or can lymphoma cause small tumors, ive also had slightly enlarged lymph nodes and trouble gaining weight...but i think my metabolism is just REALLY high..no appetite loss, no headaches, no pain w/ on lymphnodes with consumption of alcahol (alcohol) just need some answers...any advise would be great!

Hello and welcome to the forum!
As far as I know, if lymphoma metastisizes, it spreads through the lymph system first, and as far as I can find, there are no lymph nodes along your upper spine. There is a good chance they are just lipomas, but the one to determine that would be your doctor.
