I have a carotid body tumor for more than 10 years and got AIHA 6 years ago, I want to find out the cause of my AIHA. I asked my doctor many times but the answer is always it won't cause my AIHA. But I still doubt about this. I also have a cyst at one of my toothcusp, don't know will this cause AIHA? Any one has experience about this?
