What are odds cancer was missed when had scope, would they have seen thyroid, lymph nodes ect. and if cancer not the reason for scope would they noti?

Anxious?: I don't think anyone can give you odds. We don't know the providers, the labs, what you told them, etc., etc. But - you sound very anxious and that is not good for you. Consider a psych eval and some therapy to guide you in how to manage your medical anxiety most effectively. There is a balance between ignoring your symptoms and being captive to them. I really can help. For now, talk to provider.
