What is a "cone biopsy"?

A cone biopsy can be done for two different reasons: one as treatment, the other is as diagnostic, or to find out how bad the problem is. For example, if somebody has severe abnormality, or we call it dysplaysia, then we need to do a cone biopsy to see if this is all that there is there and we actually got a good sample with our colpscopy, or is there more severe problem that we are missing, for example, if there's, God forbid, cancer that we didn't pick up in the colpscopy that we did. So cone biopsy is both diagnostic and also for treatment.
