Convinced I have oral cancer

I am really struggling with the feeling I have oral cancer. I have been a heavy drinker for the last 5-6 years and a weekend drinker for several years prior. Quit cold turkey in January. My symptoms started last fall when I had gotten sick twice in a two months span. Really bad colds that lingered and allergy symptoms that to this day I can’t get rid of. I noticed white patches in the back of my throat, chronic scratchy throat for  2 months and went to an ent specialist who didn’t want to investigate but did do a biopsy because I virtually begged for it. He just kept saying it’s not cancer and even sent it off to the pathologist clinically described as a benign neoplasm. Pathologists report came back very vague as inflamed tonsillar tissue.

Went to another Ent for a second opinion and I felt again I was getting blown off. The only thing he offered to do was have his pathologist review the slides and we would talk about allergy symptoms and reflux in 6 weeks.  No thorough look in my throat even.

I took it on myself to visit a gastro doc who started right off by telling me reflux doesn’t cause a chronic sore throat! I feel like I’m being discredited every where I go. 

I did agree to medication for anxiety because I feel the overwhelming weight of all this but I feel like it’s making me more pigeon holed as a nut job.

I’ve also discovered a  swollen lump in my upper jaw. I visited my dentist who said come back in 2 weeks if it’s still there. I wanted him to X-ray it but he didn’t want to. Tomorrow is the day I go back. I’m also going to another specialist 3 hours away on Wednesday that my doctor recommended  with the referral note, I’ve already been reassured.

So long story short I just feel consumed with this fear. I’ve done a lot of reading and know that this is a hard cancer to diagnose sometimes and that coupled with the half way interest I’m receiving, is just about to take me under! Can anyone relate to me??

The dentist visit will do you the world of good! I've been having a general C word scare, so I went to the dentist in order to get that region checked and everything came back clear.

Have you got any other symptoms? Like swollen nodes or anything else at all? (Don't go looking for nodes, just if you've noticed them!)  

Do you smoke? 

I doubt 6 years of heavy drinking would be enough to cause OC either, unless you mean chronic 24/7 whiskey drinking or something. It's obviously a risk factor, but risk factors don't mean you'll definitely get it.

(Not a doctor or medical advice, just my opinion)
