Hi welcome to the health care magic Hoarseness of voice doesn t only mean cancerous growth... It can be from Laryngitis like infective or inflammatory condition as well... You are using lisinopril and if can lead excess mucus production due to release of bradykinin I would like to advise you to consult only nearby otorhinolaryngologist for laryngoscopy procedure which is OPD based procedure From laryngoscopy we can find any lesion if present over larynx After that according to examination your further treatment plan will be decided Hope your concern solved Take care
