Hello Air My Age Is 20 And I Started Smoking

Hello
Air my age is 20 and I started smoking maximum 2 years ago now from a very long time I am facing a problem my throat usually gets really strained and now I am also facing sinusitis. My throat tends to feel like ita totally blocked or something in blocking it between the collarbone area when ever I try to press my wind pipe it starts itching and I start coughing alot of mucus is blocking my throat according to the doctors but is there any possibility that it could be cancer
