i'm 19 years old now and noticed a small lump under my chin about a year ago. i booked into my local gp about it and was referred to hospital under the note of "suspected head or neck cancer". That was about ten months ago now and i have not heard any news back from my gp or the hospital which i would assume means it's nothing to worry about, however, it's still there and i've just started worrying about it again. i was wondering whether anyone else had any similar lumps and whether anyone had any thoughts on what it could actually be. i don't think that it has grown in the past year, however i do believe when i first noticed it it wasn't firm (or at least as firm as it is now.
