Can a 16 yr old get throat cancer?

I'm a 16 yr old male and I am very scared that I have throat cancer, I smoke 3 to 7 cigerattes a day and I've been smoking for about 6 months now, my throat feels pretty heavy right under my Adams apple, I do not have trouble swallowing at all, no hoarseness of voice, no blood in mucus, the only lump I think i have is the one behind my adams apple which is scaring me completely, I noticed it and felt it the first day it came out, even if I do have cancer I'm just worried about how my family would feel, I'm soooooo scared please any help, and I never heard of a 16 year old getting throat cancer
