Is it ok to visit the er for oral cancer concerns?

Please don't: The er is a place for for acute problems. The development of oral cancer is not acute and the diagnosis of it should occur in a different setting, i.e. Clinic, private practice office (dentist's office, ent's office, oral and maxillofacial surgeon's office, internist's office).

No: No. You won't get a diagnosis here. See an oral surgeon or ENT doc.
