I found a Hard lump today, on the underneath of my jaw in the center directly below my chin. It doesn't seem to move easily, and the lump and surrounding tissue feel bruised. It aches when i yawn and when i apply pressure, it also aches for i while after i have applyed pressure.

There is no history of cancer in my family as far as i am aware, my aunty had a cyst removed a few years ago from behind her ear, but that is all i can link it to.

Please advise me, i am really concerned, but dont want to trouble my mum, as she is having a difficult time....which i dont want to discuss.
