This is coming from a caregiver who recently lost her mom, due to a misdiagnosis. Get the biopsy or you will never find peace! If u dont get it done then dont come here looking for our sympathy. This disease sucks, u dont want it, Yes there are misdiagnosis, my mom had been seen by her ent since 1993 for scc. First line of treatment was surgery. Several years later she was given the speech of your cancer free. If u havent had a reaccurance by now your cured. She was so happy that day. Only to be diagnosed with stage IV a couple years later. While continued to be seen by her same ent. Get The Biopsy, and then live your life!
