Hi!

Im a 15 year old female, recently my throat has been very sore, i thought this was just because of a recent flu i had but after the flu had passed the sore throat got worse. I looked in the mirror at my throat and its very red and swolen on the left slide and what looks to be possibly an ulcer. I looked into it and also discovered throat cancer and its symptoms, i have almost all of the symptoms besides ear pain.

I should also mention; i vape and have been for about a year and a half, i used to smoke very often for a year around (4-7 cigarettes a day) but stopped arounf 2 months ago, i also drink around 1-3 times a week. Other then those things im a very healthy teenager, not overweight/underweight or I'll constantly, i eat very well and walk around an hour everyday. 

i just want to know if im overthinking this all or i should go and get checked?
