Can Something Stuck In Back Of Throat Feeling Be Sign Of Cancer ?

Starting Last Sunday the 16th I could feel something in the back of my throat like I had food stuck. A few days later I was looking into my mouth and when I depressed my tongue with my toothbrush I could see my epiglottis and knew that's where the feeling was coming from. Now when i Look into my mouth I can see my epiglottis without depressing my tongue. I saw my doctor on Friday and she said she couldn't see anything wrong and it wasn't epiglottitus because I was vaccinated when I was younger. I'm not experiencing any pain, I don't have trouble breathing or swallowing food it's just really uncomfortable being able to feel that all the time. Is this something I should be worried about?should I be able to see my epiglottis? Could this be an early sign of some sort of cancer?
A little background on me, Im 26 6'3" 180 lbs I work out 4 times a week like to stay in shape, don't smoke, never have. I drink occasionally, maybe 1-2 beers a week. There is no family members that know of that have ever had throat cancer or any cancer for that matter.
