THROT OR oral cancer!?! Help please so scared.

Hi I’m a 15 year old male. All I’ve done is a few cigarettes and like a week or two of chewing tobacco. I regret it and would never do it again. I have very bad health anxiety and have worried about oral or throat cancer many times. But this past Friday I found a bump on the side of my neck, it is quite movebale and goes all over when I press it. I find another one on the back of my neck that isn’t so moveable. I have no other symptoms of throat cancer but I do cough after laughing and have a little less breath when laying down. Do you think this is cancer and is it likely in someone of my age? I’m very scared so any help is appreciated.

in your age cancer is not frequent. Go to ENT ASAP
