I never had a doctor lie to me. Maybe play down the initial findings as a small lesion, interesting findings, until further testing was done, and sometimes they just don't know until the biopsy or complete pathology is done. Most times the white lesions are not cancerous caused by a number of things, or could be Leukoplakia, that may be precancerous stage, so your doctor is taking the right measures. The scope is called a laryngoscope or flex scope. Good luck with the biopsy.
