Thank u so much iam going the 9th to a ent my doc does not think it is cancer but she said she still wants me to go so iam and iam scared

and what iam I to exspect my first visit my doc said she was sending me for a biopsy with a referal but when I called to make appomiment did say anything about that ? And if its the size of a swollen taste bud is that good on catching it early ?
