Lumps in a 16 year old boy?

Im a 16 year old male. I have these two very small, easily movable lumps in my neck on either side of my throat. I also have a small, again, easily movable lump underneath my left clavicle. I've had gynecomastia for almost 4 years now, and i have many lipomas in my arms and chest, but they are attached to eachother sort of. The reason I'm not sure if the lumps in my neck and underneath my clavicle are lipomas is that they aren't surrounded by other lipomas like the ones in my chest and arms, they're all alone, but they still feel relatively the same. Like I said, they definitely aren't large, all of them peas sized, but I'm not sure how large a cancerous tumor or enlarged lymph node would usually be. I'll be seeing a doctor in a few days, just wondering what you think this may be.
