Hello, I am a 26 year old male and have been experiencing a lump like feeling in my throat for about 3 weeks. I have had trouble breathing through my mouth. I get sore throats on and off and also have woken with a nose bleed about a week ago which has never happened. I have had headaches for 4 months straight. The lump feels like my throat is about halfway open right behind my adams apple. I am worried that it may be throat cancer. Does anyone have any ideas?
