hey, I'm seventeen and I have a medium sized lump on the side of my neck and I've had it there for fifteen years, I've never been a smoker or into drugs but no matter how healthy or sick I am the lump stays there, it is where lymph note gland is but it never goes down in size.

as years go by, it's grew a little and now it's starting to hurt. my boyfriend just resently had a ganglion syst removed from his rist and I was wandering if this is one too or cancer related.  I would appreciate it if I got some advice about this,

thank you :)
