I think that after seeing 7 ENT specialists that you can be confident that you do not have cancer. Please try to move on with your life. I also wonder if you should see a therapist to talk about all this with and to help you put it in perspective. Maybe anxiolytics medications would help too. Relax. Many Drs have now told you that you do not have cancer.
