im 21 years old, have never smoked, a purely social drinker and only for the past 6 months. Ive been having weird sleeping sounds, when i eat i feel like my food is stuck, i feel like my chest burns, and im coughing a lot. Also when i cough when brushing my teeth, the tiniest bit of brownish reddish blood comes out. Is it possible that i have throat cancer??? can i have it without a cause? please helo and thank you verya much
