I would like to know if bleeding from the throat due to severe coughing or brushing your tongue can be associated with Throat Cancer or Emphysema? For about 4 months now I have this problem. Sometimes it feels as if I have a Sore throat, but it hurts alot. When I eat and swallow I feel like the food going down is scraping on my throat or esophagus. When I cough severely and spit the phlegm there is a streak of blood, not red red but like an orange-red color. When I brush my teeth and I brush my tongue, as far as the toothbrush goes it makes me feel like i'm going to vomit, but I end up coughing and when I spit there is streaks of blood, these are red streaks that looks like blood. I am a smoker. I've been smoking for 7 years now. Can anyone have an answer for me or should I overcome my fear and go to the doctor?
