I Found a hard lump today, on the underneath of my jaw in the center, directly underneath my chin. It doesn't seem to move much and feels like the lump and surounding tissue is bruised. It aches when i yawn and if i apply pressure.

My family has no history of cancer as far as i am aware, my aunty had a cyst removed a few years ago (it was behind her ear).

Please advise me, im very concerned, i dont want to trouble my mum as she is having her own problems at the moment...of which i would not like to discuss.
