Scared about tongue cancer

Hello, I’m a female, 24 years old. Non smoker. 59 kilos. 1.59 cm.

I have braces, have been using them for 1.5 years, I have them inside My theet too because there was something wrong with my bite so my dentist is correcting it. Lately, my ear and right jaw have been hurting a little and I found this IMG-20200718-112405616-2 hosted at ImgBB — ImgBB in the right side of My tongue.

My dentist is the best, she is very clean and always watch all of my mouth, I asked her about it and she said that I shouldn’t worry, that it doesnt look bad, I don’t know for how many months I’ve been having it but I found a photo of myself, tongue out, of 5 years ago and that thing was there! So maybe my tongue was always like that?
Oh, and I had a full blood work, chest x ray (because of a pain in my right neck) and everything came back perfect. I have health anxiety and I’m so scared because I read that oral cancer is raising on young females

hey, those are normal! those can get inflamed and stick out like small pieces of meat (even from biting), your doctor can prescribe you a cream or lotion that makes them go away in a 2 days.
