A well trained, experienced doctor can suspect something is cancerous or nothing to worry about but they wont know for certain unless its biopsied. I do not know the rate of wrong biopsies but just like anything it certainly would be possible. A biopsy is only as good as the person studying the tissue and posting the results. Human error can happen but it should be a relatively rare occurrence.
