What or where would you like them to biopsy? A biopsy is a specific removal of suspect tissue from a specific area. It is usually VERY small in sample size, sometimes only a few cells. The odds that if they took a random piece of your tonsile that they woud even get something (assuming it was there in the first place) is very small. I sent you a private email not long ago explaining the issue of enlarged tonsiles and lymph tissues as a normal function of the body dealing with common infections and irritations. It is likely time to let this idea of biopsy go and follow the recommendations of the doctors that you are seeing.
