Hey im a 16 year old male and a small bump formed on my lower lip a little over a month ago. its small, filled with clear puss and wont go away. it hurts when i bite it and feels sorta hard. i can bite off the skin on it and the clear stuff will come out a little. the next day itll become smaller but then the day after itll just grow back. if i leave it alone its still there. i even bit that whole chunk off one day when i was eating. then after the skin on my lip grew back the bump came back too. it wont leave me alone and a couple of days ago my front top four teeth started hurting and i havent done anything to them it feels like baby teeth feel like when your ripping them out . also my teeth are shifting around like sometimes my front two teeth can touch the bottom 2 front teeth but sometimes they cant at all and its really bugging me

i was just wondering if this could possibly be mouth cancer or something...

its been a massive burden on me and i will try to see a doctor sometime but my dad just keeps telling me not to worry. the symptoms i looked up said shifting of teeth, bump that wont go away, and stuff like that its just freaking me out could you please help me?

thanks
