Need Some Insight

Okay, I'm not sure where to begin with all this...My hubby has told me recently that he has had white spots in the back of his throat that if he's brushing his teeth he will run the toothbrush back there and they will break off not tasting very well, his tonsils are swollen, his lymph nodes are swollen, his gums are bleeding, his neck is swollen and stiff, he's having a hard time swallowing and chewing, his throat hurts along with his throat. He occasionally gets the chills and has been very tired. He loves his job and would do anything in the world to get up and go and he has a very hard time getting up in the morning. Apparently, this has been going on for the past few years and it's progressively getting worse. I told him he needs to go see a doctor and he's afraid to, because he knows what it is. Our insurance is changing as of Nov 1 and he has promised me to go see a doctor then. He is 36 years old and we have 3 young children. I have done my research and it all leads to some type of throat cancer. The thought has crossed my mind that it could be an infection, but my theory is I would have it and it wouldn't have gone on this long. The other thing is we were both on an antibiotic of 800 mg last year and there still there. They never went away. I'm trying to think positive but when I do all my research it all leads to the throat cancer. Any insight would be greatly appreciated!
