Thank you for your response! The doctors need to remove the other tonsil to look for the cancer in the tissue which may be small and only visible to the pathologist. But it will help them target the radiation if they do find it. It’s the most likely place for the cancer to be and if found will limit the field of the radiation. If not found there will need to be a wider field of radiation so in this case we are hoping they find it . I understand their thinking but admit it does seem a little odd to remove something hoping to find the cancer. However my reading is that tonsils are lymph nodes so it is similar to removing the neck lymph nodes in an effort to stage the cancer and plan the treatment.
