Do I have cancer?

I actually had tongue ulcers unhealed for 6 months plus they were occasionally painful. On cheeks inner I've developed white patches which once bleed . I have a buldged out voice box under my Adams apple which is painful plus I have developed another swelling under it between my esophageal and throat I guess which is also painful. I have also developed lymph nodes around my neck one which is big and not movable under my jaw and neck . I also have a shortness of breath but it's kinda improved by inhalation as I also have chronic cold and cough. I have also lost weight and sweat alot . However I have never spit or coughed up blood or excreted blood. I also have occasional ear pain. I used to smoke cigarettes 4-5 or sometimes lower daily plus I used to drink alcohol almost everyday for 1 year straight. I have quit everything though. I have also been to 3 docs one being an ent and it wasn't cancer but I still gotta check now as they are unhealed. please let me know what's wrong with me 😭
